A control circuit device for a motor is provided with a circuit board which has an electrically-conductive terminal for electrically connecting the motor with an exterior connector, a heat radiating unit which is connected with the circuit board to radiate heat generated by the circuit
A motor control device selectively turns on or off a drive transistor in-accordance with a PWM control signal Sp, such that a drive current Im supplied to a motor is adjusted. The device also samples and holds a motor current Sm for obtaining a motor current value Ih. With reference
A brush structure for a motor is provided for realizing an equalization of wear of brushes without causing an early wear of a specific brush while not necessitating a complicated conduction controlling device. A first brush, which is one of four brushes, conducted at both Lo mode and Me
