Description

集成有逆变器的电机组件 技术领域
本发明涉及电机领域，且特别地涉及一种集成有逆变器的电机组件。
背景技术
在例如电动车辆或混合动力车辆中，有将电机与逆变器集成的应用。但是二者的集成度有限，例如逆变器安装于电机的外部，电机和逆变器需要各用一套冷却水道，两个流入管道和两个流出管道的设置给车辆零部件的布置增加了难度。
另外，为了准确识别转子在周向上的转动位置，通常需要在转子附近安装位置传感器。例如图1示出了一种可能的位置传感器S的安装方式。其中，电机包括转子E1和定子E2，转子带动转轴Er转动。位置传感器S包括目标环S1和接收器S2，目标环S1呈大致环形，接收器S2呈半环形或1/4环形。目标环S1套设于转轴Er且能跟随转轴Er转动，接收器S2例如通过螺栓固定在目标环S1对面的壳体上，接收器S2与目标环S1在轴向上间隔开一定的距离。
上述设置中，接收器S2在安装时难以准确定位，接收器S2所对应的圆的圆心难以与目标环S1的圆心重合，目标环S1所在的平面容易与接收器S2所在的平面不平行，以致于影响位置传感器S的检测精度。此外，由于逆变器通常集成在电机的外周，需要使用包覆了绝缘层的、从电机内部伸至外部的线束来连接位置传感器S以获取传感器的信号。
一种可能的降低位置传感器S的安装位置误差的方法是将接收器S2也设置成完整的环形，然而这又会在轴向上占据过多的空间(或者说占据周向上由例如原来呈半环形的接收器S2未完全占据的空间)并导致材料的浪费。

(i)逆变器与电机同轴心地设置，使得整个电机组件更紧凑，电和信号的连接线的布置更方便。
(ii)接收器S2嵌设在逆变器的主体10内，且与电机同轴心地设置，使得接收器S2的定位方便且在轴向上和径向上的安装位置误差小，提高位置传感器S的安装精度和测量精度。
(iii)接收器S2与主体10通过直插式的传感器接头C1相连，连接方便且信号传输质量高。

应当理解，上述实施方式仅是示例性的，不用于限制本发明。本领域技术人员可以在本发明的教导下对上述实施方式做出各种变型和改变，而不脱离本发明的范围。例如：
(i)由于逆变器与电机共用同一个冷却套CJ，逆变器的周壳H1可以是电机的壳体的一部分，也可以将逆变器的周壳H1和电机的壳体分体设置并在轴向A上串联地连接(周壳H1和电机的壳体之间设置密封圈)。
