Description

多转子永磁同步电机 技术领域

背景技术
目前市面上应用的电机及驱动方式有很多种，其中，比较常用的几种应用在电动汽车上作为驱动的设备，如永磁同步电机、异步电机、直流电机和开关磁阻电机，其驱动方式也有几种，如自动MT波箱、手动波箱、CVT无级变速波箱、电子变速波箱等。但是，在上述电机中，不管是哪款电机，只要是配上上述的波箱或是在直驱方式时无需使用波箱的情况下，均能导致能量损失，该能量损失的部分，就是能量传输时的能量损耗。电机利用波箱传递动力，本身就是一种能量的损耗，因为电动汽车起步时，需要大扭矩及高转速先经过波箱齿轮来实现驱动，再经过汽车尾牙差速锁才传递到车轮以驱动汽车。在电机直驱方式下，虽然不用波箱，但需要大功率大扭矩来实现驱动，从而电机本身的耗能和成本也就相应地变高，同时需要大容量的电动汽车的电池，才可以应付大功率电机起步时负载的电流强度及冲击，而大容量的电池增加了车身的重量，自然而然也就增加了危险系数。

发明实施例
本发明的实施方式
本发明提供一种多转子永磁同步电机，可应用于电动汽车中。该电机通过主机 构和辅助机构协同工作，产生大扭矩使汽车更平顺有力地推动，相当于具有波箱的电机通过增加波箱的速比来推动汽车，同时，相对于增加波箱的速比，在达到输出的同等大小的扭矩，本发明的多转子永磁同步电机耗能小，因为在电动汽车达到一定速度时，辅助机构停止工作。此外，通过主机构和辅助机构协同工作，能输出不同的扭矩，进而达到输出不同的速度。
为了使本发明的目的、技术方案及优点更加清楚明白，以下结合附图及实施例，对本发明进行进一步详细说明。应当理解，此处所描述的具体实施例仅用以解释本发明，并不用于限定本发明。
图1示出了本发明较佳实施例的多转子永磁同步电机的立体结构示意图。参考图1，该电机100包括电机主轴3、依次套接于该电机主轴3上的主机构1和辅助机构4以及固定连接于主机构1和辅助机构4之间的电机中盖2。在本发明中，该电机可应用于电动汽车中，在电动汽车起步时，主机构1和辅助机构4同步工作；当电动汽车达到某一定速度时，辅助机构4不工作，仅主机构1工作；当电动汽车达到另一定的速度时，辅助机构4重新工作，以为电动汽车再次起步做好准备。
图2示出了图1中的爆炸图。参考图2，主机构1包括主定子14和主转子15，该主定子14的形状大致呈中空结构的圆柱体，且中空结构为圆柱形，在主定子14的内壁周向均匀设置有多个线槽，在线槽内设有线圈。主转子15包括铁芯151和第一永磁体组(图中未标号)，铁芯151上设置有多个磁槽151a，每一磁槽151a沿着所述铁芯151的轴线周向等间距均匀分布，第一永磁体组包括安装于铁芯上的多个磁槽151a上的多个第一永磁体152。相邻两个第一永磁体152的磁极异名。具体地，第一永磁体152呈长方形的瓦片状。如图2所示，对应地，磁槽151a也呈长方形的瓦片状。主转子15套接于电机主轴3的第二段主轴上，主定子14包围主转子15，主转子15的铁芯151的轴线与主定子14和主转子15的轴线均重合。
主机构1还包括套设在主定子14上的主定子电机壳13以及套设在主定子电机壳13上的主定子电机外壳12，主定子电机壳13和主定子电机外壳12的轴线均与主定子14的轴线重合，主定子电机壳13与主定子电机外壳12之间通过绝缘胶粘结在一起。主定子电机壳13大致呈中空结构的圆柱体，且中空结构为圆柱形，在主 定子电机壳13上设置有若干个孔槽(图中未示出)，若干个孔槽沿着轴向端面的轴线周向均匀分布，该孔槽为横截面呈圆形的柱体。
进一步地，主机构1还包括第一电机轴承16和电机前盖11，该电机前盖11的中心处设有一通孔，其大小与电机主轴3的轴向端面的大小一致；并列的两个第一电机轴承16套接于电机主轴3上，电机前盖11通过并列的两个第一电机轴承16套接于该电机主轴3上，并与主定子电机壳13固定连接。优选地，电机前盖11的端面上设置有若干个孔槽，每个孔槽沿着端面的轴线周向均匀分布，电机前盖11与主定子电机壳13通过孔槽对应连接。在本实施例中，为了使电机前盖11与主定子电机壳13之间的连接稳固，并节省材料，主定子电机壳13的外壁的轴向中间区域设置有凹槽13a，这样，主定子电机壳13的相对两端分别构成了窄部13b，主定子电机壳13上的孔槽可穿过该窄部13b，使得电机前盖11能与主定子电机壳13稳固连接。对应地，电机前盖11上的孔槽也为横截面呈圆形的柱体。
当然，电机前盖11的孔槽和主定子电机壳13上的孔槽也可分别为横截面呈方形的柱体。
辅助机构4包括辅助转子组件40、辅助定子组件44、单向轴承体41以及固定连接于辅助转子组件40和辅助定子组件44之间的电机后盖43。单向轴承体41、电机后盖43以及辅助定子组件44依次套接于电机主轴3上，辅助转子组件40套接于单向轴承体41上，这样，辅助转子组件40通过单向轴承体41套接于电机主轴3上。当然，辅助转子组件40还可以通过电子耦合器套接于电机主轴3上。
具体地，在本实施例中，单向轴承体41包括多个单向轴承411、单向轴承内套413以及单向轴承外套412。单向轴承内套413大致呈中空结构的圆柱体，且中空结构为圆柱形，其外壁呈阶梯状，且其相对两端的轴向端面的半径小于中间区域的轴向端面的半径。单向轴承内套413套接于电机主轴3上，单向轴承内套413的一端套设有两个并列的单向轴承411、另一端套设有两个并列的单向轴承411，从而该单向轴承内套413和多个单向轴承411构成一整体，单向轴承外套412包围该整体，从而形成了单向轴承体41。具体地，单向轴承外套412大致呈中空结构的圆柱体，且中空结构为圆柱形，多个单向轴承411的外壁贴合于单向轴承外套412的内壁，即两者的半径相同。
在本实施例中，电机后盖43的中心处设有一通孔，其大小与电机主轴3的轴向端面的大小一致；电机后盖43穿过电机主轴3，并通过第二电机轴承42套接于电机主轴3上。
图3示出了图2中的辅助转子组件和单向轴承体的分解图。参考图3，辅助转子组件40包括第一辅助转子401、第二辅助转子403和套接于单向轴承体41上的固定套402，第一辅助转子401和第二辅助转子403分别套接于单向轴承体41的相对两端，固定套402的内壁贴合于单向轴承外套412的外壁，且单向轴承体41与固定套402之间通过绝缘胶粘结在一起。具体地，固定套402大致呈中空结构的圆柱体，且中空结构为圆柱形，在固定套402上设置有若干通孔，每个通孔沿着轴向端面的轴线周向等间距均匀分布。
同时，参考图4，第一辅助转子401和第二辅助转子403均呈圆盘状，第一辅助转子401或第二辅助转子403均包括呈中空结构且一轴向端面开口的圆柱状的主体a以及设置于主体a的中心处的连接部b。连接部b大致呈圆筒状，连接部b的内边缘上设置有若干个凹肋c，每一凹肋c沿着连接部b的轴线周向等间距均匀分布；连接部b上设置有若干个通孔(图中未标号)，每一通孔沿着连接部b的轴线周向等间距均匀分布。
进一步地，第一辅助转子401和第二辅助转子403均还包括第二永磁体组(图中未标号)，第二永磁体组包括多个第二永磁体d，第二永磁体组设置在主体a内，每一第二永磁体d沿着主体a的轴向端面的轴线周向均匀分布，相邻两个第二永磁体d的磁极异名，这样第二永磁体的构成了第一辅助转子401或第二辅助转子403的开口的轴向端面。具体地，第二永磁体d呈扇形的瓦片状。
进一步地，参考图3，第一辅助转子401和第二辅助转子403分别与固定套402的相对两端固定连接。具体地，第一辅助转子401通过第一辅助转子401上的通孔和固定套402上的通孔与固定套402的一端固定连接，同样地，第二辅助转子403通过第二辅助转子403上的通孔和固定套402上的通孔与固定套402的另一端固定连接，且第一辅助转子401的第二永磁体d构成的开口的轴向端面和第二辅助转子403的第二永磁体d构成的开口的轴向端面相对。
进一步地，辅助转子组件40还包括用于将单向轴承体41固定于电机主轴3的顶 圈404，该顶圈404套接于电机主轴3上，并与单向轴承体41沿着所述电机主轴3的轴线并列设置。这样，在电机主轴3转动时，可以防止辅助转子组件40偏离，同时，防止电机主轴3相对于单向轴承体41的转动。具体的，顶圈404大致中空结构的圆柱体，且该中空结构为圆柱形。
进一步地，同时，参考图5，辅助定子组件44包括旋变硅钢片443、辅助定子442和旋变线圈座441，旋变硅钢片443套接于电机主轴3的尾端上，辅助定子442套接于旋变硅钢片443上，旋变线圈座441套接于辅助定子442中，并且旋变线圈座441和辅助定子442分别与电机后盖43固定连接，这样，构成了旋转变压器，其是一种输出电压与转子转角保持一定函数关系的感应微电机，也是一种将角位移转换为电信号的位移传感器，将电信号稳定地传递到电机控制器，再由控制器控制电机的转速及扭矩。具体地，辅助定子442为一种旋变线圈定子，其的形状大致呈中空结构的圆柱体，且中空结构为圆柱形，在辅助定子442的内壁周向均匀设置有多个线槽；旋变硅钢片443为横截面大致呈三角形的柱体。
在本实施例中，辅助机构4还包括六角螺母45，六角螺母45套接于电机主轴3的尾端上，并与辅助定子组件44沿着电机主轴3的轴线并列设置，用于将辅助定子组件44固定于电机主轴3上，这样可以防止辅助定子组件44偏离。
进一步地，在本实施例中，辅助机构4还包括辅助电机外壳46和旋变线圈后盖47。辅助电机外壳46包围辅助转子组件40，且其相对两端分别与电机中盖2和电机后盖43固定连接。优选地，辅助电机外壳46的相对两端分别与电机中盖2和电机后盖43固定连接，辅助电机外壳46、电机中盖2和电机后盖43上分别设置有若干个通孔，通孔对应连接。辅助电机外壳46大致呈中空结构的圆柱体，且中空结构为圆柱形，其内壁设置有若干线圈(图中未示出)，线圈的正面大致呈H型，线圈沿着辅助电机外壳46的内壁的轴线周向均匀分布。旋变线圈后盖47盖设在辅助定子组件44上，且与电机后盖43固定连接。
由于主机构1和辅助机构4分别套接于电机主轴3上，根据主机构1和辅助机构4的特点，电机主轴3可以为呈阶梯状的圆柱体，如图所示，阶梯状的圆柱体的轴向端面的半径各不相同，从左到右，阶梯状的圆柱体的轴向端面的半径呈现递减趋势。
综述，本发明的多转子永磁同步电机无需使用波箱来实现驱动，并且耗能小。
以上所述，仅为本发明较佳的具体实施方式，但本发明的保护范围并不局限于此，任何熟悉本技术领域的技术人员在本发明揭露的技术范围内，可轻易想到的变化或替换，都应涵盖在本发明的保护范围之内。因此，本发明的保护范围应该以权利要求的保护范围为准。
