Abstract
A frame of an electric motor opens in one end. A heat sink, to which a control substrate is connected, closes an opening of the frame. The frame includes a cylinder portion to which a stator is fixed, and a bottom portion that extends inward in the radial direction from the cylinder portion. A rotor is rotatably mounted in the frame to face the stator in the radial direction. A circumferential groove is formed in the bottom portion to face a stator coil in an axis of rotation direction. The circumferential groove is filled with a heat transfer gel. A coil end portion of the stator coil is inserted into the heat transfer gel.
