Abstract
PURPOSE:To economize the power consumption in a control system and also improve starting characteristic by obtaining a binary digital data corresponding to the phase difference between a revolution phase signal and a reference signal and by performing control of a driving circuit according to the difference between the said digital data and the revolution speed signal. CONSTITUTION:A revolution phase signal F is obtained by having a detector 8 corresponding to a rotating disc 7 which is connected to a motor 6, the said signal F is compared with a reference signal H using a digital phase comparator 14 and obtain a binary digital data D corresponding to the phase difference. Also a revolution speed signal A is obtained by corresponding another detector 12 to the rotating disc 7 and the signal B which passed through a pulse shaping device 13 is input to a digital pulse width modulator 15. The binary digital data D and the signal B are compared by the digital pulse width modulator 15 and a driving circuit 5 is controlled by the difference P obtained by the modulator 15. As a result, the control system can be highly integrated, miniaturized, economized in power consumption and stabilized as well.
