A dynamo-electric machine (500) according to the present invention is provided with a rotor (510) and an inverter housing (531). The inverter housing has a circumferential wall (541, 542) which is provided radially inside a stator winding (521); and an electrical module (532) that constitutes an inverter is provided radially inside the circumferential wall. The rotor comprises: a cylinder part (513) that has an inner circumferential surface to which a magnet unit (512) is affixed; an end plate (514) which is provided at a first end of the cylinder part in the axial direction, and to which a rotary shaft (501) of the rotor is affixed; and a disk-like rotor cover (670) which extends radially inwardly from a second end of the cylinder part in the axial direction at least to the position wherethe electrical module is provided in the radial direction.
一种旋转电机(500),包括转子(510)以及逆变器外壳(531)。逆变器外壳具有设置在定子绕组(521)的径向内侧的周壁(541、542),在周壁的径向内侧设置有构成逆变器的电气模块(532)。转子具有:圆筒部(513),在其内周面固定有磁体单元(512);端板(514),其设置于圆筒部的轴向上的第一端,并且固定有转子的旋转轴(501);以及圆板状的转子罩(670),其至少在径向上从圆筒部的轴向上的第二端朝向径向内侧延伸到设置有电气模块的位置。
