Abstract
A stator is fixed to a frame of an electric motor. A rotor is rotatably mounted to the frame to face the stator in a radial direction. A heat sink, to which a control substrate is attached, is mounted in one end of the frame. A heat transfer plate is interposed between heat-generating elements formed on the control substrate and the heat sink to absorb variations in a distance therebetween, the heat transfer plate allow heat to be transmitted from the heat-generating elements to the heat sink. The heat transfer plate includes a frame body mounted to the heat sink and a plurality of contact strips that flexibly protrude from the frame body and that abut the heat-generating elements.
