Abstract
PURPOSE: By setting control of both the phase difference between starting synchronizing signal and rotary position signal based on driving coil counter electromotive voltage at either zero or at such level of not causing any trouble at time of switch-over, it is designed to obtain smooth and stabilized changeover form synchronous revolving condition to the revolving condition based on counter electromotive voltage.
