Abstract:
A heat sink member divides a circuit board into a first circuit part and a second circuit part. The first circuit part includes circuit elements, such as a transistor, an electric current sensing resistor and a choke coil, which generate heat upon operation thereof. The second circuit part includes a control circuit, which controls operation of the motor.
