Abstract

PURPOSE:To perform accurate speed control by electrifying the coils of each motor group according to the output of AND circuit receiving a current switching signal for the coils of each motor group and a pulse modulated signal according to the speed control signal of motor. CONSTITUTION:The output of the rotation position detector 2 for the motor 1 is put in the switching signal forming circuit 3 to form the current switching signals Sa, Sb, and Sc which are in turn supplied to the one input terminal of the AND circuits 11a to 11c. And, the detected signal Sd of the motor speed detector 7 is compared with the reference speed signal Se at the erring speed detecting circuit 8 to form the erring signal Sf which is in turn given to the pulse modulation circuit 10. The modulated signal Sg of the pulse modulation circuit is supplied to the other input terminal of the AND circuits 11a, 11b, and 11c, and from each AND circuit, the driving signals Aa to Ac which are the product of the current switching signals Sa to Sc and the pulse modulated signal Sg can be obtained. The signals control the current flowing in the coils 5a to 5c.
