A frame has upper and lower surfaces that extend in a perpendicular direction to a motor output shaft, donut-shaped conductive plates are mounted respectively on the upper and lower surfaces, and the conductive plates both include connection-forming terminal portions provided on inner and outer peripheral sides thereof. An inverter circuit is constituted by a power module formed from a plurality of switching elements, a power supply terminal is provided on one side of a package forming the power module, while an output terminal connected to a winding terminal for supplying power to a motor and a control terminal connected to a control signal are provided on an opposing side. The terminal portions on the inner peripheral sides of the conductive plates are connected to the power supply terminal of the power module, and the control board is connected to the control terminal of the power module.
