ABSTRACT:
A power control unit causes a high supply voltage to be intermittently chopped to provide energy pulses in a core transformer and the energy in the core is discharged into a capacitor with the capacitor constituting the power source for a stepping motor and with the extent of the energy pulse accepted by the capacitor being determined by the condition of the capacitor which in turn is set by the instantaneous operating state of the motor.
