Abstract

PURPOSE:To maximize a counter-electromotive force and accordingly maximize efficiency, by supply current to the only section of maximum magnetic flux in the magnetic field of a field system. CONSTITUTION:Hall elements 11a, 11b are fixed on the armature side, and confronted with the pole surface of a magnet rotor, Hall output is obtained. At the initiation of driving, current is supplied reciprocally to armature coils 5a, 5b at 180 degrees, and after that, current is supplied at 90 degrees. By the output of an OR circuit 53a, transistors 48a, 48b are made conductive, and current is supplied to armature coils 5a, 5c at the right side, and by the output of an OR circuit 53b, transistors 48c, 48d are made conductive, and current is supplied to the armature coils 5a, 5c on the counter direction. Armature coils 5b, 5d is controlled in conduction by the output of an AND circuit 51c, 51d.
