Abstract: In the present invention, a circuit board has: a substrate body disposed on the side opposite to a stator with respect to a plate-shaped part of a center piece; and heat-generating elements mounted to the surface of the substrate body on the plate-shaped part side and disposed within the range of the radial direction of a rotor housing. A heat-dissipating portion of a heat sink is disposed on the plate-shaped part side with respect to the circuit board, and the heat-dissipating portion comes into contact with the heat-generating elements or contacts said elements via a heat-transferring material. A guide portion is formed, on the plate-like part, facing the heat-dissipating portion in the axial direction of a motor unit. The guide portion forms an air-guiding flow channel, the channel being between the heat-dissipating portion and the guide portion, in a shape such that air taken in from an air intake port is guided from the outside in the radial direction of the motor unit towards the center.
