ABSTRACT:
A control circuit for a stepping motor comprises a voltage multiplier which, in synchronism with the motor timing pulses from a pulse generator multiplies the supply-voltage in such a manner as to obtain an energizing voltage which, at commencement of the excitation of each motor winding, has a value which is a multiple of the value of the supply voltage, in order to reduce the rise time of the current in the windings, and to thus improve the dynamic torque availability. A voltage doubler and tripler are described as examples of the circuit.
