ABSTRACT:
A voltage control device for controlling a driving voltage applied to a motor having a plurality of phases is provided with a switching circuit for changing the motor driving voltage from one voltage value over to another among a plurality of voltage values. The switching circuit is arranged to have a stop phase of the motor excited by a lower driving voltage than a rotation driving voltage in adjusting the stop phase at which the motor has been stopped.
