Abstract

To increase the speed of rotation of a step-by-step motor in the forward or reverse direction, the motor is driven at its "synchronism" speed. For the motor to perform N steps at high speed involves applying a starting drive pulse that induces forward or reverse motion, then applying N-2 alternating maintenance pulses and finally applying a stopping pulse. Preferably, a circuit using the coupling coefficient of the motor as a servo-control parameter defines the instants at which the maintainance or stopping pulses are applied.
