ABSTRACT:
A motor driving apparatus includes a motor, a signal generating device for generating a Pulse Width Modulation binary signal, a control device for applying a current to the motor, a current detecting device for detecting the current applied to the motor, and a current blocking device for blocking the current applied to the motor for a predetermined time when the current applied to the motor exceeds a predetermined value. The current blocking device is synchronized at an alternative cycle of the binary signal, whereby it is possible to limit the current applied to the motor during the overload of the motor.
