ABSTRACT:
A stator having a stator core about which a coil is wound is secured to an aluminum frame. A magnet-embedded type rotor is rotatably accommodated inward of the stator. A circuit substrate is attached to the surface of the aluminum frame opposite to the surface to which the stator is secured. A control circuit and hall ICs for detecting the rotational position of the rotor are mounted on the circuit substrate. Detection signals of the hall ICs are received by the control circuit. The control circuit supplies a drive current to the coil of the stator in accordance with the detection signals.
