Abstract

PURPOSE:To improve the drive characteristics of a pulse motor by connecting a capacitor in parallel with a drive coil switching circuit of the motor and connecting it via a sensitive resistor to a constant-current source made of semiconductor chopper having a control circuit, thereby suppressing the resonance voltage. CONSTITUTION:A pulse motor 21 is driven by the output of a constant-current source 1, is rotated at an angle corresponding to the opening and closing of a drive coil switching circuit 11 controlled in opening and closing by a distributor, and is stepwisely driven as prescribed. Further, a capacitor (C) 31 is connected in parallel with the circuit 11. The motor 21 has drive coils 22, 23 and a stator 24, the vibration at the mechanical resonance point varies the current of a sensitive resistor (R) 16 and is outputted to the terminal 1a of the source 1 via a semiconductor chopper 3 and a reactor 6, is flowed through C31 to R16, the voltage detected by the R16 is fed back to the control circuit 4, thereby stabilizing the output voltage V0 and reducing the resonance phenomenon.
