ABSTRACT:
A motor driving apparatus includes a power circuit that controls an output voltage via a feedback resistance. The power circuit varies the output voltage by changing a value of the feedback resistance at a time of at least one of activation and termination of a motor, thereby enabling to activate the motor at any one of a high speed and a low speed.
