ABSTRACT:
A stepping motor provided with an energizing circuit for simultaneously energizing two phase windings from current sources. For actively damping the rotor movements an active network has been provided which measures the difference between the voltages across the two phase windings and in accordance with a suitably selected function converts it into two currents which are in phase opposition to each other, and which are applied to the two phase windings.
