ABSTRACT:
A driving system for reversibly rotating a D.C. brushless motor is disclosed. The system comprises Hall generators for detecting positions of a rotor, and a drive circuit for controlling conduction and interruption of current applied to stator windings making use of output of said Hall generators. The system further comprises an inversion control circuit including a switch for reversibly switching polarities of an applied power source in order to reversibly rotate the D.C. motor thereby reversibly inverting the D.C. motor in response to signals from the power source whose polarities vary alternately.
