201141013 六、發明說明： 【發明所屬之技術領域】 本發明係關於一種用於磁極電機之轉子，更特定言之， 本發明係關於一種易於大量製造之用於磁極電機之轉子。 【先前技」術】 多年來，諸如磁極電機、爪極電機、倫德爾（LundeU)電 機及横向磁通量電機（TFM)之電機設計正變得越來越引人 關注。利用此等電機之原理之電機最早*Alexanderss〇n及 Fessenden於大約1910年揭示。對於越來越關注之最重要原 因之一在於該設計對於（例如）感應式電機、切換磁阻電機 及甚至永久磁鐵無刷電機可實現一極高的轉矩輸出。此 外，此類電機之優點在於其線圈通常易於製造。然而，該 設計之缺陷之一在於該等電機之製造通常相對昂貴且該^ 電機會經歷一高洩漏磁通量，其導致一低功率因數及需要 更多磁性材料《該低功率因數要求一大型的功率電子電路 (或當該電機被同步使科之電源供應），此亦提高總驅動 之體積、重量及成本。 該磁極電機定子之基本特徵為使用一中心單一繞組，其 將磁性地饋送由軟磁芯體結構形成之多#。接㈣軟磁^ 體係形成於該繞組周圍’然Μ於其他f用電機結構⑽ 組係形成於該齒芯體段周圍。該磁極電機佈局之諸實例有 時被認為是(例如)爪極、魚尾紋式(Ο·—)、倫德爾或 TFM電機。具有埋人式磁鐵之磁極電機之另外特徵為包含 由轉子磁極段分離之複數個永久磁鐵之—主動轉子結構。 153059.doc 201141013 該主動轉子結構由偶數個分段構成，然而一半數量之分段 由軟磁材料製成及另一半數量之分段由永久磁鐵材料製 成。該等永久磁鐵材料經配置使得該等永久磁鐵之磁場方 向係大體上為圓周型，亦即北極及南極分別指向一大體上 圓周方向。 傳統上，轉子係藉由生產一相當大數量的個別轉子分段 (通常為1 0至50個）而製成。然而’該組裝過程係複雜且耗 時，由於大量的組件應結合至一起導致一明確界定之氣隙 以維持該電機之性能。由該等永久磁鐵分段之相對極化方 向在組裝期間趨於相互排斥該等轉子磁極段，所以該組裝 過程係更複雜的。 WO2009116935揭示一種轉子及一種用於製造一轉子之 方法。其中減少了個別零件之數量由此減少了組裝該轉子 之所需時間。然而此方法導致該等個別零件之複雜度及成 本提高。此外，因為該等組件將顯示出在熱處理期間可導 致類似非所需變形的彎曲之截面區域的較大變化，所以很 難達到較好的總公差。在組裝期間(特別是若在組裝期間 該結構必需稍微變形以滿足幾何公差之需求）薄整合式橋 接段亦可造成強度問題。 大致上需要提供-種在生產及組裝中相對便宜的用於磁 極電機的轉子°進—步需要提供具有較好丨±能參數（諸如 面結構穩定性、低磁阻、有效率的磁通路徑引冑、低 及慣性等等）之此一轉子。 【發明内容】 153059.doc 201141013 根據一第一樣態，本文所揭示係用於一磁極電機之一轉 子之諸實施例’該轉子經組態以產生用於與該磁極電機之 一定子之一定子磁場相互作用之一轉子磁場，其中該轉子 包括： -一管型支撐件結構，其界定一圓周安裝表面，該管型 支撐件結構在該安裝表面中包括複數個長形凹口，該等長 形凹口於該管型支撐件結構之一軸向中延伸； -複數個永久磁鐵，其在該轉子之圓周方向中磁化以產 生該轉子磁場’該等永久磁鐵藉由抽向延伸之轉子磁極段 於該轉子之圓周方向中相互分離，該等轉子磁極段用於定 向由該等永久磁鐵在一徑向中產生之該轉子磁場， 其中至少一永久磁鐵或至少一轉子磁極段徑向延伸至少部 分進入該複數個凹口之一者内。因此選自—永久磁鐵及二 轉子磁極段之至少一組件延伸至少部分進入該複數個凹口 之者内’使侍該組件之部分延伸出該凹口。 因此’在λ中描述之轉子之諸實施例中，該等永久磁鐵 及轉子磁極段形成與該管型支撐件結構共軸的一管型轉子 結構。該管型轉子結構之圓周表面之一者連接至該管型支 樓件結構之圓周安裝表I為此目的，該等永久磁鐵之一 二或所有及/或該等轉子磁極段之一些或所有自該管型轉 子結構之該等圓周表面之該一者徑向突出並進入該管型支 撐件結構之安裝表面之各別凹口内。 文中描述之轉子之諸實施例提供一有效率且可靠的組裝 過程’其巾在料個別組件上提供甚至具有相對大公差的 153059.doc 201141013 一明確界定之氣隙，且甚至當待組裝之該等組件具有有限 的強度及脆性行為時亦是如此。 在一些貫施例中，該複數個凹口經調適以容許徑向延伸 至少部分進入該複數個凹口之一者之至少一永久磁鐵或至 少一轉子磁極段之位置可被徑向調整，以便容許延伸出凹 口之部分之徑向長度可被調整。 一凹口可經調適以藉由具有大於一平均組件所需之深度 之一深度的一凹口而容許該組件之位置可被徑向調整。由 此由於生產的變異，經生產具有平均長度以上的一徑向長 度之一組件可更深地插入該凹口内，容許延伸出該凹口之 部分之徑向長度為一平均組件之長度。經生產具有平均長 度以下之一徑向長度之組件可使用相反的原理。 在本發明之-些實施财κ申至少部分進入該複數個 凹口之一者内之至少一永久磁鐵或至少一轉子磁極段與該 凹口之兩側壁接觸（亦即，藉由一黏合劑與該兩側壁直接 接觸或分離）。 該轉子可為任何類型的轉子，諸如經調適可在一外定子 内部徑向旋轉之一内轉子，或經調適可環繞一内定子旋轉 之一外轉子。 該複數個永久磁鐵可經配置使得環繞圓周之每第二個磁 鐵之磁化方向相反。由此個別轉子磁極段僅與顯示相同極 性之磁鐵相互作用。 該等凹口可沿著該管型支撑件結構之安裝表面週期性地 定位。該等凹口之壁可於一徑向中延伸進入該管型支樓件 153059.doc 201141013 結構内。因此，延伸至少部分進入該複數個凹口之一者内 之該永久磁鐵或轉子磁極段可於一徑向中延伸出該凹口。 在一些實施例中，該圓周安裝表面係由該管型支撐件結 構之一内表面界定。此設計對於外轉子係有利的。 在一些實施例中，該圓周安裝表面係由該管型支撐件結 構之一外表面界定。此設計對於内轉子係有利的。 該管型支撐件結構可包括任何數量的凹口（諸如2與2〇〇 之間，5與60之間或10與30之間）。在本發明之一些實施例 中’所有凹口係與一永久磁鐵或一轉子磁極段配合。該管 型支撐件結構可具有任何軸向長度。在本發明之一些實施 例總’該官型支揮件結構之轴向長度對應於該等永久磁鐵 及/或該等轉子磁極段之軸向長度。在本發明之一些實施 例中，該等凹口沿著該管型支撑件結構之整個轴向長度延 伸。在本發明之一些實施例中，該等凹口沿著該支標件結 構之軸向長度之一限制部分延伸…凹口可由於一徑向中 延伸進入由—第三壁連接之管型支撐件結構之-第-及一 第-平订側壁形成。在本發明之—些實施例中，該第三壁 係垂直於該第一及筮-辟 ^ 第一J。在本發明之一些實施例中，該 二壁係f曲的’具有大致可跟隨該管型支料結構之彎 曲部分的—曲線。該轉子可具有任何大小。該管型支撲件 結構之該等凹口可經锢噢t 主又存件 '調適以谷許該等轉子磁極段或該等永 广之位置可被禮向調整以便容許延伸出該凹口之部分 之從向長度可被調整。 6亥轉子（例如該管型支擇件結構）可包括用於轉移藉由該 153059.doc 201141013 轉子與該定子之間相互作用而產生之轉矩之構件。在一些 實施例巾’該㈣支㈣結構連接至-㈣於轉移產生之 轉矩。例如，與用於安裝該等磁鐵及/或轉子磁極段之安 裝表面相對之該管型切件結構之表面可被諸安裳該轉 子至一轂、一軸等。 製造任何產品之成本皆與終端產品之精度要求緊密相 關。高精度產品需要複雜且昂責的生產技術或—相對大的 生產產品之退件帛，兩種途徑皆可導致較高的生產成本。 使用咼精度要求以確保一磁極電機之轉子與定子間之一有 效率相互作用。這導致用於該轉子之組件（例如，該等轉 子磁極段及該等永久磁鐵）之對應的高精度要求。然而， 藉由用包括複數個凹口之一支撐件結構供應該轉子，一轉 子磁極段或永久磁鐵可經徑向調整進入該管型支撐件結構 之一凹口内，由此容許徑向延伸出該凹口之部分之長度可 被調整。這將降低該等轉子磁極段或永久磁鐵之精度要 求，由此相應地降低生產成本。在一些實施例中，在定位 於一凹口中之組件及該凹口之背部間之間隙用一適合的材 料填充，諸如環氧樹脂膠之一適合類型的黏著劑。 在一些實施例中，該支撐結構可包括在該等凹口中之該 等轉子磁極件或永久磁鐵之徑向調整期間用於軸向運送膠 水之小凹口。該等小凹口可為該膠水提供各別通道以軸向 地逸出該磁極件或永久磁鐵下面之區域且由此增強公差調 整精度。 藉由提供該轉子磁極段及永久磁鐵可被插入其中之一框 153059.doc 201141013 架，該㈣支#件結構亦可用以簡化該等轉子零件之组裝 過程。該管型支禮件結構件將額外地心提供—更剛㈣ 轉子’透過使用該管型支稽件結構件彳降低該轉子歪斜之 風險。由於可以高精度生產該管型支料結構所以所得轉 子將具有降低幾何形狀變動’提高該產品之整體品質並降 低人為錯誤之風險。由此可降低需丟棄的轉子數量。 本發明之一優勢係在該管型支撐件結構中具有凹口，容 許該等永久磁鐵或轉子磁極段之位置被修改，可處置個別 組件之更高公差；此亦包含該管型支撐件結構之公差。另 一優勢係該管型支撐件結構提供一框架，該框架易於組裝 如本發明之一轉子，且使其具有良好的同心度。 在一些實施例令，該管型支撐件結構可為一單一組件或 或以複數個片段或模組提供 例如於轴向及/或圓周方向 中分段。類似地，該等永久磁鐵及/或磁極件之一些或各 者可被模組化，例如，在軸向中分段或分成若干組件。 在本發明之一些實施例中，該轉子磁極段係由諸如軟磁 粉末之一軟磁材料製成。藉由由軟磁粉末製成該等轉子磁 極段，該轉子之製造可被簡化且利用有效的三維磁通量路 徑之優點磁通量集中可係更有效率。 在本發明之一些實施例中，該管型支撐件結構係由諸如 鋁、塑膠之一無磁材料（例如擠製鋁、射出成型塑膠等等 及/或類似材料及/或其他適合之無磁材料）製成。藉由生產 一無磁材料之管型支撐件結構’該轉子之磁性性質係未受 干擾。 153059.doc 10· 201141013 根據一第一態樣，該等永久磁鐵係配合至該管型支撐件 結構之該等凹口内部’且一轉子磁極段被置於兩相鄰永久 磁鐵之間。藉由將該等永久磁鐵配合至該支撐件結構之該 等凹口内部，該等永久磁鐵徑向延伸超過該等轉子磁極 奴。这將容許更有效率的利用該等永久磁鐵產生之磁通 量。 在本發明之一些實施例中，該轉子磁極段被配合至該支 撐件結構之該等凹口内部。 在本發明之一些實施例中’該等永久磁鐵或該等轉子磁 極段藉由由該凹口之該等側壁形成之一摩擦配合而配合至 射型支揮件結構之該等凹σ内部。藉由使用—摩擦配合 係可提供固疋3等永久磁鐵或轉子磁極段t —簡單且可靠 ’方法D亥摩擦配合可藉由設計出比該等永久磁鐵或轉子 磁極段稍小的凹口而產生。藉由該等凹口壁之一可控變形 可促進摩擦力的調整，例如藉由—些整合的設計特徵，比 如用足夠小的所需力即可彎曲以防止損壞該磁極段或磁鐵 之材料的一唇緣。 根據-第二態樣，本發明係關於用於如上文揭示之一轉 立口轉子磁極段，其中當轉子磁極段配合至該凹口中時 2自界定-徑向軸之該凹口徑向延伸，&中該轉子磁極 丰又包括， 山第—恆定寬度區域，其形成該轉子磁極段之一第— 末二其經調適至少部分地配合於該支撐件結構之一凹口 、中該第一恆定寬度區域具有兩平行側壁使得在該第 153059.doc -11 - 201141013 一恆定寬度區域中之該轉子磁極段之寬度為恆定， -一漸縮區域，其起始於該第一恆定寬度區域結束之點 處，其中該漸縮區域具有兩非平行側壁使得在該漸縮區域 中之該轉子磁極段之寬度為非恆定的。 因此，兩相鄰轉子磁極段之漸縮區域對於一永久磁鐵形 成具有平行壁的一狹槽開口，由此促進該昂貴的永久磁鐵 之—簡單、低成本的幾何形狀。 在本發明之一些實施例中，該第一恆定寬度區域之該等 側壁係與該徑向轴平行。 在本發明之一些實施例中，該漸縮區域之該等側壁係與 該也向轴非平行。 爲了本發明描述之目的，當一轉子磁極段被配合於該管 ，支樓件、，構巾時，該轉子磁極段之長度被定義為沿著該 管型支撐件結構之徑向軸延伸之尺寸，#該轉子磁極段被 δ於„亥g型支撐件結構中時，該轉子磁極段之高度被定 義為沿著該管型支撐件結構之軸延伸之尺寸，且該轉子磁

201141013 該轉子磁極段之總長度之5%至20%之間。在本發明之一些 實施例中’該第一恆定寬度區域之長度對應於該轉子磁極 段之總長度之8%至12%之間。 該漸縮區域可具有任何長度。在本發明之一些實施例 中’該漸縮區域之長度對應於該轉子磁極段之總長度之 400/。至95%之間《在本發明之一些實施例中，該漸縮區域 之長度對應於該轉子磁極段之總長度之6〇%至9〇%之間。 該漸縮區域之長度由該等永久磁鐵之徑向長度決定。在本 發明之一些實施例中，該漸縮區域之兩側壁係朝向該中心 徑向軸成角度的直壁使得該轉子磁極段之寬度係沿著該徑 向軸隨著距該第一恆定寬度區域之距離增加而單調遞減； 备忒轉子磁極段使用於一外轉子中時此設計係有利的。在 本發明之一些實施例中，該漸縮區域之兩側壁係遠離該中 心徑向軸成角度的直壁使得該轉子磁極段之寬度係沿著該

在本發明之一些實施例中，該轉子磁極段進一步包括其 起始於該漸縮區域結束之點處之一第二恆定寬度區域，並 形成該轉子磁極段之一第二末端，其中該第二恆定寬度區 域之該等側壁係相互平行使得該轉子磁極段之寬度在該第 二恆定寬度區域中為恆定的。 在一些實施例中，該第二恆定寬度區域之兩側壁係與該 徑向轴平行。 6亥第一怪定寬度區域可具有任何長度。在本發明之一些 實施例中’該第二恆定寬度區域具有對應於該轉子磁極段 之總長度之2。/。至20%間之一長度。在本發明之一些實施例 中，該第二恆定寬度區域具有對應於該轉子磁極段之總長 度之5%至15%之一長度。 藉由具有一第二位定寬度區域，由兩相鄰轉子磁極段形 成之空間之寬度可自該第二怪定寬度區域起始之點開始減 小。由此可防止置於該空間中的一磁鐵於一徑向中掉出空 穴。 在本發明之一些實施例中，該磁極段之高度係大於長度 且該長度係大於寬度。 根據一第二態樣’本發明係關於一種使用粉末壓緊製造 153059.doc -14 - 201141013 如上文及下文中所述之—轉子磁極段之方法，其包括以下 步驟： 獲得-模，其具有與如上文及下文中所述之一轉子磁 ⑹又相反的形狀，其包括-第-恆定寬度區域及一第二恆 定寬度區域； -用諸如鐵或鐵基粉末之磁性粉末填充該模； -壓縮該模中之可變形磁性粉末，例如，使用兩個或更

海綿鐵粉末。在這種情況下，該術語「大體上純」意味著 該粉末應為大體上無雜質及雜質氧、碳及氮之數量應保持 在一最小值。平均微粒大小大致上為300微米以下且1〇微 米以上。 然而，只要軟磁性質充足且粉末適合用於模壓緊，任何 軟磁金屬粉末或金屬合金粉末皆可被使用。 該等粉末微粒之電絕緣件可由一無機材料製成。美國專 利第6348265號（以引用方式併入本文）中揭示之類型的絕緣

Field of the Invention The present invention relates to a rotor for a magnetic pole motor, and more particularly to a rotor for a magnetic pole motor which is easy to mass-produce. [Previous Technology] For many years, motor designs such as pole motors, claw pole motors, LundeU motors, and transverse flux motors (TFM) are becoming more and more interesting. The motors that used the principles of these motors were first revealed in about 1910 by Alexanderss〇n and Fessenden. One of the most important reasons for increasing attention is that the design achieves a very high torque output for, for example, induction motors, switched reluctance motors and even permanent magnet brushless motors. In addition, the advantage of such a motor is that its coils are generally easy to manufacture. One of the drawbacks of this design, however, is that the manufacture of such motors is typically relatively expensive and the electrical device experiences a high leakage flux that results in a low power factor and requires more magnetic material. "The low power factor requires a large power. The electronic circuit (or when the motor is synchronized to supply the power supply) also increases the size, weight and cost of the total drive. The basic feature of the pole motor stator is the use of a central single winding that will magnetically feed the multiples formed by the soft magnetic core structure. A (4) soft magnetic system is formed around the winding, and then the other motor structure (10) is formed around the tooth core segment. Examples of the pole motor layout are sometimes considered to be, for example, claw poles, crow's feet (Ο·-), Lundell or TFM motors. An additional feature of a pole motor having a buried magnet is an active rotor structure comprising a plurality of permanent magnets separated by a rotor pole segment. 153059. Doc 201141013 The active rotor structure consists of an even number of segments, however half of the segments are made of soft magnetic material and the other half of the segments are made of permanent magnet material. The permanent magnet materials are configured such that the magnetic field directions of the permanent magnets are substantially circumferential, i.e., the north and south poles respectively point in a substantially circumferential direction. Traditionally, rotors have been made by producing a relatively large number of individual rotor segments (typically 10 to 50). However, the assembly process is complex and time consuming, as a large number of components should be combined to result in a well defined air gap to maintain the performance of the motor. The assembly process is more complicated by the relative polarization directions of the segments of the permanent magnets tending to mutually repel the rotor pole segments during assembly. WO2009116935 discloses a rotor and a method for manufacturing a rotor. This reduces the number of individual parts and thus reduces the time required to assemble the rotor. However, this approach results in increased complexity and cost of such individual parts. Moreover, because these components will exhibit large variations in the cross-sectional area of the bend that can cause similar undesired deformation during heat treatment, it is difficult to achieve better overall tolerances. Thin integrated bridge sections can also cause strength problems during assembly (especially if the structure must be slightly deformed to meet geometric tolerances during assembly). It is generally necessary to provide a rotor for a magnetic pole motor that is relatively inexpensive in production and assembly. It is necessary to provide a magnetic flux path having better 丨± energy parameters such as surface structure stability, low reluctance, and efficiency. The rotor of the enthalpy, low and inertia, etc.). SUMMARY OF INVENTION 153059. Doc 201141013 According to a first aspect, disclosed herein is an embodiment of a rotor for a pole motor that is configured to generate one of a stator magnetic field interaction with one of the stators of the pole motor. a rotor magnetic field, wherein the rotor comprises: - a tubular support structure defining a circumferential mounting surface, the tubular support structure including a plurality of elongated recesses in the mounting surface, the elongated recesses One of the tubular support members extends axially; a plurality of permanent magnets that are magnetized in the circumferential direction of the rotor to generate the rotor magnetic field. The permanent magnets are extended to the rotor pole segment by the rotor. Separating from each other in a circumferential direction, the rotor pole segments are for orienting the rotor magnetic field generated by the permanent magnets in a radial direction, wherein at least one permanent magnet or at least one rotor pole segment extends at least partially into the plurality of Inside one of the notches. Thus, at least one component selected from the group consisting of a permanent magnet and a second rotor pole segment extends at least partially into the plurality of recesses to extend a portion of the component out of the recess. Thus, in the embodiments of the rotor described in λ, the permanent magnets and rotor pole segments form a tubular rotor structure that is coaxial with the tubular support structure. One of the circumferential surfaces of the tubular rotor structure is connected to the circumferential mounting table of the tubular branch structure. For this purpose, one or both of the permanent magnets and/or some or all of the rotor pole segments The one of the circumferential surfaces from the tubular rotor structure projects radially into the respective recesses of the mounting surface of the tubular support structure. Embodiments of the rotor described herein provide an efficient and reliable assembly process. The towel provides even relatively large tolerances on individual components of the 153059. Doc 201141013 A well defined air gap, and even when the components to be assembled have limited strength and brittle behavior. In some embodiments, the plurality of notches are adapted to permit radial extension of at least a portion of the at least one permanent magnet or at least one rotor pole segment that is at least partially into the plurality of recesses to be radially adjustable The radial length of the portion that allows the extension to extend out can be adjusted. A notch can be adapted to allow the position of the assembly to be radially adjusted by a notch having a depth greater than one of the depths required for an average component. As a result of the variation in production, one of the components having a radial length above the average length can be inserted deeper into the recess, allowing the radial extent of the portion extending beyond the recess to be an average component length. The opposite principle can be used for producing components having a radial length below one of the average length. At least one permanent magnet or at least one rotor pole segment of at least a portion of the plurality of recesses of the present invention is in contact with both sidewalls of the recess (ie, by a bonding agent) Direct contact or separation from the two side walls). The rotor can be any type of rotor, such as an inner rotor that is adapted to be radially rotatable within an outer stator, or an outer rotor that is adapted to rotate around an inner stator. The plurality of permanent magnets can be configured such that the magnetization direction of each of the second magnets around the circumference is opposite. Thereby the individual rotor pole segments interact only with magnets exhibiting the same polarity. The recesses are periodically positionable along the mounting surface of the tubular support structure. The walls of the recesses extend into the tubular branch member 153059 in a radial direction. Doc 201141013 within the structure. Thus, the permanent magnet or rotor pole segment extending at least partially into one of the plurality of recesses can extend out of the recess in a radial direction. In some embodiments, the circumferential mounting surface is defined by an inner surface of the tubular support structure. This design is advantageous for the outer rotor system. In some embodiments, the circumferential mounting surface is defined by an outer surface of the tubular support structure. This design is advantageous for the inner rotor system. The tubular support structure can include any number of notches (such as between 2 and 2, between 5 and 60, or between 10 and 30). In some embodiments of the invention 'all notches are mated with a permanent magnet or a rotor pole segment. The tubular support structure can have any axial length. In some embodiments of the invention, the axial length of the main profile structure corresponds to the axial length of the permanent magnets and/or the rotor pole segments. In some embodiments of the invention, the recesses extend along the entire axial length of the tubular support structure. In some embodiments of the invention, the recesses extend along a restricted portion of one of the axial lengths of the support member structure... the recesses may extend into a tubular support connected by the third wall in a radial direction The --and-first-stitched sidewalls of the piece structure are formed. In some embodiments of the invention, the third wall is perpendicular to the first and the first J. In some embodiments of the invention, the 'wall' of the two walls has a curve that substantially follows the curved portion of the tubular material structure. The rotor can be of any size. The notches of the tubular member structure can be adjusted by the main storage member to adjust the position of the rotor poles or the permanent positions to be adjusted to allow the extension to be extended. The length of the part can be adjusted. A 6-turn rotor (eg, the tubular support structure) may be included for transfer by the 153059. Doc 201141013 A component of the torque generated by the interaction between the rotor and the stator. In some embodiments, the (four) branch (four) structure is coupled to - (iv) the torque generated by the transfer. For example, the surface of the tubular cut structure opposite the mounting surface for mounting the magnets and/or rotor pole segments can be spliced to a hub, a shaft, or the like. The cost of manufacturing any product is closely related to the accuracy requirements of the end product. High-precision products require complex and rigorous production techniques or relatively large production products, and both can lead to higher production costs. The 咼 precision requirement is used to ensure efficient interaction of one of the rotor and stator of a pole motor. This results in corresponding high precision requirements for the components of the rotor (e.g., the rotor pole segments and the permanent magnets). However, by supplying the rotor with a support structure comprising a plurality of notches, a rotor pole segment or permanent magnet can be radially adjusted into a recess of one of the tubular support structures, thereby allowing radial extension The length of the portion of the recess can be adjusted. This will reduce the accuracy requirements of the rotor pole segments or permanent magnets, thereby correspondingly reducing production costs. In some embodiments, the gap between the component positioned in a recess and the back of the recess is filled with a suitable material, such as one of a suitable type of adhesive for the epoxy glue. In some embodiments, the support structure can include small recesses for axially transporting glue during radial adjustment of the rotor pole pieces or permanent magnets in the recesses. The small recesses provide separate passages for the glue to axially escape the area beneath the pole piece or permanent magnet and thereby enhance tolerance adjustment accuracy. By providing the rotor pole segment and the permanent magnet can be inserted into one of the frames 153059. Doc 201141013 frame, the (four) branch structure can also be used to simplify the assembly process of the rotor parts. The tubular member structural member will provide additional centering - the more just (four) rotor 'by reducing the risk of skewing the rotor by using the tubular member structural member. Since the tubular type of material structure can be produced with high precision, the resulting rotor will have a reduced geometrical variation' to increase the overall quality of the product and reduce the risk of human error. This reduces the number of rotors that need to be discarded. One advantage of the present invention is that there is a recess in the tubular support structure that allows the position of the permanent magnet or rotor pole segments to be modified to handle higher tolerances of individual components; this also includes the tubular support structure Tolerance. Another advantage is that the tubular support structure provides a frame that is easy to assemble as one of the rotors of the present invention and that has good concentricity. In some embodiments, the tubular support structure can be a single component or can be provided in a plurality of segments or modules, for example, in an axial and/or circumferential direction. Similarly, some or each of the permanent magnets and/or pole pieces may be modularized, for example, segmented or divided into components in the axial direction. In some embodiments of the invention, the rotor pole segments are made of a soft magnetic material such as a soft magnetic powder. By making the rotor pole segments from soft magnetic powder, the manufacture of the rotor can be simplified and the use of an effective three-dimensional magnetic flux path can be more efficient in concentrating the magnetic flux. In some embodiments of the invention, the tubular support structure is made of a non-magnetic material such as aluminum or plastic (eg, extruded aluminum, injection molded plastic, etc. and/or the like and/or other suitable non-magnetic materials) Made of material). The magnetic properties of the rotor are undisturbed by the production of a tubular support structure of a non-magnetic material. 153059. Doc 10· 201141013 According to a first aspect, the permanent magnets are fitted into the interior of the recesses of the tubular support structure and a rotor pole segment is placed between two adjacent permanent magnets. The permanent magnets extend radially beyond the rotor poles by mating the permanent magnets into the recesses of the support structure. This will allow for more efficient use of the magnetic flux generated by the permanent magnets. In some embodiments of the invention, the rotor pole segments are mated to the interior of the recesses of the support structure. In some embodiments of the invention, the permanent magnets or the rotor pole segments are mated to the interior of the recesses σ of the shooter structure by a friction fit formed by the sidewalls of the recess. By using a friction-fitting system, a permanent magnet such as a solid or a rotor pole segment t can be provided - simple and reliable. The method D-hai friction fit can be designed by designing a notch smaller than the permanent magnet or the rotor pole segment. produce. The controlled deformation of one of the recess walls facilitates the adjustment of the friction force, for example by means of some integrated design features, such as bending with a small enough force to prevent damage to the pole segment or magnet material. a lip. According to a second aspect, the invention relates to a rotary rotor pole segment for use in a reaming as disclosed above, wherein the recess extends radially from the delimiting-radial axis when the rotor pole segment is fitted into the recess, And the magnetic pole of the rotor further includes a mountain-constant width region, which forms one of the rotor pole segments, the second and second of which are adapted to at least partially fit into one of the recesses of the support structure, the first The constant width region has two parallel side walls such that at the 153059. Doc -11 - 201141013 The width of the rotor pole segment in a constant width region is constant, - a tapered region starting at the point where the first constant width region ends, wherein the tapered region has two non-parallel The sidewalls are such that the width of the rotor pole segments in the tapered region is non-constant. Thus, the tapered regions of the two adjacent rotor pole segments form a slot opening having parallel walls for a permanent magnet, thereby facilitating the simple, low cost geometry of the expensive permanent magnet. In some embodiments of the invention, the sidewalls of the first constant width region are parallel to the radial axis. In some embodiments of the invention, the sidewalls of the tapered region are non-parallel to the axis. For the purposes of the present description, when a rotor pole segment is mated to the tube, the leg member, and the scarf, the length of the rotor pole segment is defined to extend along the radial axis of the tubular support structure. Dimensions, when the rotor pole segment is δ in the Hi-type support structure, the height of the rotor pole segment is defined as the dimension extending along the axis of the tubular support structure, and the rotor pole & The width is defined as the length 0 of the length and height of the rotor pole segment. The height of the rotor pole segment is determined by the first and second width regions and the tapered region. The length substantially corresponds to the depth of the 4th notch, such as the height of the side walls of the notch (axial Ρ in some embodiments of the invention, the length of the first constant width region corresponds to the rotor pole segment invention In some embodiments, the total length is between 2% and 30%. The length of the first constant width region corresponds to 153059. Doc •12· 201141013 The total length of the rotor pole segment is between 5% and 20%. In some embodiments of the invention, the length of the first constant width region corresponds to between 8% and 12% of the total length of the rotor pole segments. The tapered region can have any length. In some embodiments of the invention, the length of the tapered region corresponds to 400/ of the total length of the rotor pole segments. Between 95% "In some embodiments of the invention, the length of the tapered region corresponds to between 6% and 9% of the total length of the rotor pole segment. The length of the tapered region is determined by the radial length of the permanent magnets. In some embodiments of the invention, the two sidewalls of the tapered region are straight walls that are angled toward the central radial axis such that the width of the rotor pole segment is along the radial axis along the first constant width The distance between the regions increases and monotonically decreases; this design is advantageous when the rotor pole segments are used in an outer rotor. In some embodiments of the invention, the two sidewalls of the tapered region are angled straight walls away from the central radial axis such that the width of the rotor pole segment is along the radial axis along the first constant width The distance between the regions increases and monotonically increases, and this design is advantageous when the rotor pole segments are used in an inner rotor. In some embodiments of the invention, to ensure the cylindrical shape of the rotor, the rotor pole segments preferably include a tapered region. As described above, the tapered region ensures that the width of the rotor magnetic segment is enlarged for the inner rotor and is used for the outer rotor. However, by having a first constant-width region adapted to be positioned in one of the recesses of the tubular support structure, the assembly of the rotors using the magnetic poles can be simplified because of the rotor magnetic poles.

This reduces production costs. The first constant width region is further used to ensure a stronger fit when the rotor segments are used in the inner rotor. In some embodiments of the invention, the rotor pole segment further includes starting from the tapered region a second constant width region at a point of end and forming a second end of the rotor pole segment, wherein the sidewalls of the second constant width region are parallel to each other such that the width of the rotor pole segment is at the second constant Constant in the width area.

In some embodiments of the invention, the second constant width region has a length corresponding to 5% to 15% of the total length of the rotor pole segment. By having a second predetermined width region, the width of the space formed by the two adjacent rotor pole segments can be reduced from the point at which the second strange width region begins. Thereby, a magnet placed in the space can be prevented from falling out of the cavity in a radial direction.

The present invention is not in the field of a magnetic pole motor 100, and is shown in a schematic exploded perspective view in Fig. 1a. 1 J" A pole motor stator 1 is characterized in that a center single winding 20 is used, and a soil edge T to a single winding 2 〇 magnetically feeds a multi-tooth formed by a soft magnetic core structure. Next, the body is formed around the winding 2〇, but for other common motor structure components is formed around the individual core segments. Examples of the pole motor layout are sometimes considered to be, for example, claw pole motors, crow's feet, 俭del or electric motors. More specifically, the pole motor 1 已 has been shown to include two stator core slaves 14, 16 each having a plurality of teeth and being substantially circular; disposed in the first and second circles A wire 圏2〇 between the stator core segments and a rotor 3〇 including a plurality of permanent magnets 22.

To form a closed circuit flux path. The motor of the figure is of the radial type because the stator teeth project toward the rotor in the radial direction, in which case the stator surrounds the rotor.

The current state of the art method is to produce such segments as individual components, and the number of segments is often quite large 'typically 10 to 50 individual segments. The permanent magnets 22 are configured such that the direction of the magnetic field of the permanent magnets is substantially circumferential, that is, the north and south poles thereof face a substantially circumferential direction, respectively. Further, the first permanent magnet 22 is counted in the circumferential direction to have a magnetic field direction in the opposite direction with respect to the other permanent magnets. The magnetic action of the soft magnetic pole segments 24 in the desired motor configuration is completely three dimensional and requires the soft magnetic pole segments 24 to efficiently carry various magnetic fluxes with high magnetic permeability in all three spatial directions. The conventional design using one of the laminated steel sheets does not exhibit the required high magnetic permeability in the direction perpendicular to the plane of the steel sheets and is useful here using a soft magnetic structure and material. The current state of the art has an isotropic nature of more than 13⁄4.

An example of a rotor that can be used as part of the pole motor shown in Figures la to b will be described in more detail below. It will be appreciated that the rotors described in this application can be used with the stator of a different type of pole motor as described above. Figure 2a shows a tube type 153059 of an outer rotor according to some embodiments of the invention. Doc -20· 201141013 Support structure 2〇1. The tubular support structure 2〇1 has a radius and a height, wherein the height extends along an axial axis of the tubular support structure 2〇1. The tubular-type support member mechanism 2G1 includes a plurality of notches 2 that are periodically positioned around a circumference of the support member structure 2 to a circumferential mounting surface (the inner surface of the tubular-type support structure 201). 2. The tubular support structure 201 can be made of a non-permeable material such as a non-magnetic material such as aluminum or plastic.

The rotor pole segment 4〇1 comprises three regions: a first constant width region 402, a tapered region 4〇3 and a second constant width region 4〇4. The first constant width region 402 is adapted to at least partially fit into a recess in one of the floor structures. The first constant width region 4〇2 includes two side walls parallel to one of the radial axes of the rotor magnetic segment 401, thereby ensuring that the width of the rotor pole segment 401 is constant within the first constant width region 4〇2 . The length of the first constant width region may correspond approximately to the depth of the notches (e.g., the extent of the two sidewalls of the notches). The tapered region 4〇3 includes two straight sidewalls that have an equal but opposite angle with respect to a radial axis of one of the rotor pole segments 401 such that the width in the tapered region follows the first strange The distance of the width region 4 0 2 increases and monotonically decreases.

The second constant width region 4〇4 includes two side walls that are parallel to the radial axis of the rotor pole segment 401. It is thereby ensured that the width of the rotor pole segment 401 is constant in the second constant width region.

In some embodiments of the invention, the rotor pole segment includes only a first constant width region 402 and a tapered region 403. Figure 5 illustrates a method of producing a rotor pole segment 502 in accordance with some embodiments of the present invention. The rotor pole section 502 is produced by filling a mold 501 with iron or iron-based powder and compressing the iron powder by two punches 505 and 506. The die 105 has, for example, the opposite shape of the desired rotor pole segment as shown in Figure 4, wherein the lengths of the first and second constant width regions 503 and 504 of the die 501 are extended. This allows the punches 505 and 506 to move radially in one of the resulting rotor pole segments 502, partially into the first and second strange width regions 503 and 504 of the mold, thereby compressing the mold 5〇1 The iron powder in the middle forms the rotor pole segment 502.

This breaks the permanent magnet 603 enclosed in the space from radial slipping out of the rotor. Figure 7a shows a rotor in accordance with some embodiments of the present invention, the rotor further including an air gap clamp 605. The air gap clamp ensures proper positioning of the rotor pole segments during manufacture of the rotor.

In the motor of Figures 9 and 1, the stator teeth project toward the rotor in a radial direction, in which case the rotor surrounds the stator. However, the stator can be equally placed externally with respect to the rotor. Embodiments of the rotor described herein can be used in single phase and/or multiphase motors. 5H active rotor structure 3〇 can be composed of even number of segments 22, 24, one of which is 153059.

These segments can be produced in individual components. For purposes of illustration, only the magnetic active portion of the rotor is shown in Figures 9 through 1〇. The tubular branch structure described herein is not explicitly shown in Figures 9 through 1. The permanent magnets 22 are configured such that the direction of the magnetic field of the permanent magnets is substantially circumferential', i.e., the north and south poles respectively face a generally circumferential direction. Further, every second permanent magnet 22 is counted in the circumferential direction to have a magnetic field direction opposite to its adjacent permanent magnet. The magnetic action of the soft magnetic pole segments 24 in the desired motor configuration is completely three dimensional and the soft magnetic pole segments 24 are capable of efficiently carrying various magnetic fluxes with high magnetic permeability in all three spatial directions. The design of the s rotor 30 and the stator has the advantage of concentrating the flux from the permanent magnet 22 such that the surface of the rotor 3 facing one of the teeth of the stator can be from adjacent permanent magnets 22. The entire magnetic flux of both presents to the surface of the tooth facing the tooth. This flux concentration can be seen as a function of the area of the permanent magnet 22 for each pole #24 (separated by the tooth-facing area). In particular, due to the circumferential displacement of the teeth, the teeth facing a pole segment may result in an active air gap k$ that extends only partially across the axial extent of the pole segment, from the entire axial extent of the dedicated permanent magnet. The magnetic flux is directed in the axial and radial directions toward the magnetic pole segments of the active air gap. The magnetic flux properties of each of the magnetic segments 24 make it possible to use weak, low cost permanent magnets as permanent magnets 22 in the rotor and to achieve extremely high air gap flux densities. The magnetic pole segment made of magnetic powder can promote the passage of 153059. Doc -26 - 201141013 The concentration makes the 3D flux path valid. In addition, this design also makes it possible to use these magnets more efficiently than the use of magnets in corresponding types of motors.

The embodiment 16 shown in Figures 9 and 1 is formed as the same component. Two specific words 153059.doc •27· 201141013 The stator segments include one of the flanges 18 protruding toward the other stator core segment. In the assembled stator, the flanges 18 abut each other and form an axial flux bridge that allows an axial flux path between the stator core segments to be used in an assembled stator for an outer rotor motor. The coil thus surrounds the back of the stator core formed by the flange 18. Each of the teeth 102 has an interface surface 262 that faces the air gap. During operation of the motor, the magnetic flux is transmitted through the interface surface 262 via the air gap and through a corresponding interface surface of one of the pole pieces of the rotor. Figure 1 la shows an active portion of one example of a 3-phase pole motor, but Figure lib shows an example of one of the stators of the motor of Figure na. The motor includes a stator 10 and a rotor 30. The stator 10 contains three stator phase segments 1〇a, b, 〇. Each is associated with the description in Figures 9 and 10. Specifically, each stator phase segment includes a pair of respective stator assembly pairs 14a, 16a; 14b, 16b; and 14c, 16c' each of which holds a circumferential winding (6) to ^, respectively. As in the examples of Figures 9 and 10, therefore, each of the electromagnetic pole motor stator phase segments 10a to c includes a center coil 20a to c (e.g., a single winding) which is magnetically fed by a soft magnetic core The multi-dentate ridge 2 formed by the body structure. More specifically, the respective stator phases 10a to c of the electromagnetic pole motor 1 shown include two core segments 14 'each core segment comprising a plurality of teeth 1 〇 2 and being substantially annular 'disposed on a coil 20 ❶ between the first and second circular stator core segments, and further a stator core segment 丨 4 and a coil 2 每个 of each stator phase surround a common axis and the plurality of stator core segments 14 The teeth 1 〇 2 are configured to be directed outwardly. In the example of Figure 11, the rotor 3 is configured to be coaxial with the stator 10 and surround the stator to form a gap between the stator and the teeth 153059.doc 28 - 201141013 2 of the rotor. The rotor is provided as alternating permanent magnets 22 and pole portions 24 as described with respect to Figures 9 and 28, but extending axially across all stator phase segments. Although the #«实&example has been described and illustrated in detail, the present invention is not limited to the scope of the subject matter defined in the following claims, and the embodiments may be implemented in other ways. It is to be understood that other embodiments may be utilized and modified in the structure and function of the invention. The embodiments of the present invention disclosed herein can be used for electric bicycles to bite other electric drive vehicles (specifically, lightweight vehicles) with straight-wheel drive motors: such applications require high torque, relatively low speed and low cost. These requirements can be met by having a motor in a relatively small number of poles in a small geometry that utilizes a small number of permanent magnets and coils to match the cost requirements by enhancing the rotor assembly procedure. Several components are listed in the device request, and several of these components may be embodied by the same item of hardware t4.
