産業上の利用分野
本発明は比較的小型をモータに多用されている
隈取りモータに関するものである。DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a relatively small shaded motor, which is often used as a motor.
従来例の構成とその問題点
従来より隈取りモータは色々なものが開発され
て来たが、主巻線が巻きやすく、また主巻線とコ
アの絶緑を確保しやすい等の理由によつて、第
８，９図に示されるような形状のモータが使用さ
れるようになつて来た。Conventional configurations and their problems Various types of shaded motors have been developed over the years. , motors having shapes as shown in FIGS. 8 and 9 have come into use.
つまり、１は主コアであり鋼板が積層されて作
られており、極２，２′には隈取り巻線３，３′が
設けられている。 That is, the main core 1 is made of laminated steel plates, and the poles 2 and 2' are provided with shaded windings 3 and 3'.
また主コアは１積層された鋼板がばらばらにな
らないように鋼板の板厚の半分だけプレス機によ
つてずらした部分を互にかん合するいわゆる半落
とし部４によつて多数の鋼板が一体に形成されて
いる。 In addition, in the main core, a large number of steel plates are integrated into one by a so-called half-drop part 4, in which parts of the laminated steel plates are shifted by a press machine by half the thickness to prevent them from coming apart. It is formed.
さらにコアス１にはロータ（図示せず）が挿入
される開孔５及び主巻線６を巻いたボビン７の中
に挿入された柱状のコア８がかん合される切欠き
９が設けられている。 Further, the core 1 is provided with an opening 5 into which a rotor (not shown) is inserted, and a notch 9 into which a columnar core 8 inserted into a bobbin 7 around which a main winding 6 is wound is fitted. There is.
以上のような構造の従来の隈取りモータは製造
に際して、主巻線６をボビン７に巻く時は単体の
ボビン７に巻線をすればよいため、極めて巻線が
しやすく、主コア１及び柱状のコア８と主巻線６
とはボビン７によつて絶緑されるため極めて絶緑
も確保しやすい。 When manufacturing the conventional shaded motor with the structure described above, winding the main winding 6 on the bobbin 7 can be done by winding it on a single bobbin 7, which makes winding extremely easy. core 8 and main winding 6
It is extremely easy to ensure that the green is completely green because the bobbin 7 is used to ensure that the green is completely green.
しかし、主コア１と柱状のコア８との間は固く
かん合されていないと磁気抵抗が増し、能率が著
しく低下する。 However, unless the main core 1 and the columnar core 8 are tightly interlocked, magnetic resistance will increase and efficiency will drop significantly.
依つて主コア１の極２と極２′の間を連結して
主コア１が分割されていない一体形状にし、切欠
き９の柱状のコア８をかん合するようにしなけれ
ばならなかつた。 Therefore, it was necessary to connect the poles 2 and 2' of the main core 1 so that the main core 1 had an undivided, integral shape, and to engage the columnar core 8 in the notch 9.
このため極２と極２′の間で磁束が一部短絡し、
多少能率の悪いものであつた。 Therefore, the magnetic flux is partially short-circuited between pole 2 and pole 2',
It was somewhat inefficient.
発明の目的
本発明は以上の点に着目し、能率の良い隈取り
モータを得るものである。Purpose of the Invention The present invention focuses on the above points and provides a highly efficient shaded motor.
発明の構成
本発明は複数の板体を積層して形成したコアの
一部の板体を極と極の間で連結し、その他の板体
を極と極の間で隙間を形成しているため極と極の
短絡磁束が少なく能率の良いものである。Structure of the Invention The present invention includes a core formed by laminating a plurality of plates, in which some of the plates are connected between the poles, and other plates are used to form gaps between the poles. Therefore, short-circuit magnetic flux between poles is small, and efficiency is high.

が設けられている。 The main core 10 also has a pair of auxiliary windings 13, 13'.
is provided.
主コア１０を構成する鋼板のうち主コア１０の
両端に位置する鋼板１０−１は第５図に示すよう
に極１２と極１２′の間が連結しており、鋼板１
０―１の間に位置する鋼板１０−２は極１２と極
１２′の間に隙間１４，１４′が設けられている。 Among the steel plates constituting the main core 10, the steel plates 10-1 located at both ends of the main core 10 are connected between poles 12 and 12' as shown in FIG.
The steel plate 10-2 located between the poles 12 and 12' has gaps 14 and 14' between the poles 12 and 12'.
１５は主コア１０の隙間１４′の近傍に設けた
切欠きである。 15 is a notch provided in the vicinity of the gap 14' of the main core 10.
さらに、主コア１０の切欠き１４，１４′の近
傍には４つの半落とし１６が設けられている。 Furthermore, four half-cuts 16 are provided in the vicinity of the notches 14, 14' of the main core 10.
１７は補コアであり、主巻線１８を巻いだボビ
ン１９に挿入され主コア１０にかん合されてい
る。 Reference numeral 17 denotes an auxiliary core, which is inserted into a bobbin 19 around which the main winding 18 is wound and is engaged with the main core 10.
次に主コア１０の製造方法について説明をす
る。 Next, a method for manufacturing the main core 10 will be explained.
第７図に示すように、ロール状に巻いた長い板
状の鋼板２０を第１のパンチ機２１に供給し、鋼
板２０を打ち抜いて第５図に示す鋼板１０−１を
作成する。次に一部の鋼板１０−１を第２のパン
チ機２２に供給し、極１２と極１２′の間を打ち
抜いて鋼板１０−２を作成する。 As shown in FIG. 7, a long plate-shaped steel plate 20 wound into a roll is supplied to a first punching machine 21, and the steel plate 20 is punched out to create a steel plate 10-1 shown in FIG. Next, a portion of the steel plate 10-1 is supplied to the second punching machine 22, and a portion between the poles 12 and 12' is punched out to form a steel plate 10-2.
そして、残りの鋼板１０−１を第２のパンチ機
２２より作成された鋼板１０−２の両端に重ねて
プレス機２３で圧接する。 Then, the remaining steel plate 10-1 is stacked on both ends of the steel plate 10-2 produced by the second punch machine 22 and pressed by the press machine 23.
このようにして出来た主コア１０に隈取り巻線
３，３′を取り付ける。 Shading windings 3, 3' are attached to the main core 10 thus produced.
また、主コイル１８に挿入された補コア１７を
主コア１０に圧入する。 Further, the auxiliary core 17 inserted into the main coil 18 is press-fitted into the main core 10.
この後ロータ（図示せず）やフレームを取り付
けるのであるが、この点は一般的であるので説明
を省略する。 After this, a rotor (not shown) and a frame are attached, but since this point is common, the explanation will be omitted.
以上の説明のモーターは通電されて動作する時
は極１２と極１２′の間に隙間１４，１４′が形勢
されている為、極１２と極１２′の間の磁気抵抗
が大きく能率が良い。 When the motor described above is energized and operates, gaps 14 and 14' are formed between the poles 12 and 12', so the magnetic resistance between the poles 12 and 12' is large and the efficiency is high. .
さらに、極１２と極１２′の間に隙間が形成さ
れているにもかかわらず、主コア１０は鋼板１０
−１によつて連結されているため、補コア１７を
圧入することができる。 Furthermore, despite the gap formed between the poles 12 and 12', the main core 10 is connected to the steel plate 10.
Since they are connected by -1, the auxiliary core 17 can be press-fitted.
この圧入に際し、極１２の上端と極１２′の上
端は互に離れる方向の力を受け極１２の上端は下
向きの分力を受けるが切欠き１５によつてこの分
力は打ち消され鋼板１０−１が変形することがな
い。 During this press-fitting, the upper end of the pole 12 and the upper end of the pole 12' receive a force in the direction of separating them from each other, and the upper end of the pole 12 receives a downward component force, but this component force is canceled by the notch 15, and the steel plate 10- 1 will not be deformed.
また隙間１４，１４′の付近に半落とし１６が
設けられているため隙間１４，１４′の付近でう
なりが発生することがない。 Further, since the half drop 16 is provided near the gaps 14, 14', no beat occurs near the gaps 14, 14'.
発明の効果
本発明な複数の板体を積層して形成したコアの
一部の板体を極と極の間で連結し、その他の板体
を極と極の間で隙間を形成しているため極と極の
短絡磁束が少なく能率の良いもである。Effects of the Invention Some of the plates of the core formed by laminating a plurality of plates according to the present invention are connected between the poles, and other plates form gaps between the poles. Therefore, there is less short-circuit magnetic flux between poles, resulting in high efficiency.
