本发明的核心是提供了一种电机，实现了电机的一体化，减小了电机体积和重量。
下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。
请参考图1和图2，本发明实施例提供了一种电机，包括电机部件2和控制器部件1，电机部件2包括电机壳体21、电机转子23和电子定子22，控制器部件1包括控制器壳体15，电机部件2和控制器部件1同轴布置且为一体安装连接，电机壳体21与控制器壳体15的横截面外形一致。
该电机采用一体安装连接结构，控制器部件1和电机部件2同轴布置，因此，与现有的分体式电机相比，该电机的总体积仅比电机部件2多出约1/3，总体积比目前的分体式电机的总体积减小约1/4，减小了体积，减轻了重量，不需要现场安装，外形最简单。
如图5所示，在本实施例中，控制器壳体15内还设置有直流出线腔152和控制出线腔151，直流出线腔152用于容置直流出线；控制出线腔151用于容置控制出线。直流出线腔152和控制出线腔151可以凸出控制器壳体15的外表面，也可以位于控制器壳体15的外表面以内，该电机的电机部件2与控制器部件1之间的电缆线、信号线均集成在控制器壳体15和电机壳体21内，提高了电机的防护等级，防护等级能够达到IP67。由于线缆位于壳体内部，因此，电缆线和信号线可以采用防护等级较低的线缆，防护等级可以降为IP55，线缆成本约减少现有的分体式电机成本的1/10；功率电缆变短，电缆线路损耗 减小，而且现场减少接线的工作。
进一步地，在本实施例中，控制器冷却介质流道设置在控制器壳体15内，电机冷却介质流道设置在电机壳体21内，且控制器冷却介质流道与电机冷却介质流道相连通。由于冷却介质流道均设置在壳体内，采用封闭流道，因此，进一步提高了防护等级，且控制器冷却介质流道与电机冷却介质流道相连通，简化了介质流通结构。
更进一步地，控制器冷却介质流道与电机冷却介质流道的截面尺寸一致，提高了两个冷却介质流道的连通的密封性，且加工简单。

作为优化，控制器壳体15的截面内圈和电容器外壳132的截面的外形均为六边形，通过六边形和六个棱边的结构实现定位支撑连接。当然，截面形状还可以为三角形、四边形、五边形或八边形等多边形。
如图4和图5所示，进一步地，在本实施例中，电容器外壳132的每个棱边均设置有第一定位结构1321，控制器壳体15的内圈每个棱边均设置有与第一定位结构1321支撑定位的第二定位结构153。电容器外壳132和控制器壳体15通过第一定位结构1321和定位结构153实现了稳定可靠的支撑和定位。
具体地，第一定位结构1321为定位凹槽，相应地，第二定位结构153为定位凸起；或者第一定位结构1321为定位凸起，相应地，第二定位结构153为定位凹槽。在一个电容器外壳132上，第一定位结构1321可以全部为定位槽或定位凸起，或者同时具有定位凹槽和定位凸起，相应地，控制器壳体15上的第二定位结构153可以全部为定位凸起或定位凹槽，或者同时具有定位凸起和定位凹槽，只要能够实现第一定位结构1321和第二定位结构153的配合支撑定位即可。
进一步地，在本实施例中，电容器131与电容器外壳132之间的缝隙填充有导热胶，用于固定电容器131并散热，提高了电容器组件13的散热性能；控制器壳体15的每个内壁面和对应的电容器外壳132的外壁面之间均紧密贴 合固定一个功率组件14，功率组件14的发热量均匀散到控制器壳体15上，散热能力最大化。

在本实施例中，为了保护控制器部件1内的电器元件不受热损坏，在本实施例中，控制组件17与电机部件2的电机内部端盖25之间设置有隔热垫。
在本实施例中，大部分结构件采用挤压铝型材，能源耗费低于压铸铝型材。
