ABSTRACT:
A DC motor apparatus which can be started with a power supply having a small current capacity and which provides a large driving force. The DC motor apparatus comprises a permanent magnet in a rotor of the DC motor, a plurality of coils provided at a stator of the DC motor, a distributor for controlling the switching of current paths to the coils and a position detector for detecting a rotational position of the rotor of the motor to output switching signal to the distributor. A pulsating unit is further provided for pulsating currents supplied to the coils whereby a current flowing from the distributor to any one of the coils can be pulsated when the DC motor is activated, resulting in easy starting the DC motor.
