Circuit arrangement for the generation of stepping pulses for the acceleration of a stepper motor

摘要

A circuit arrangement is disclosed which generates stepping pulses which will drive a stepper motor within its range of optimum load angle. The stepping pulses are formed by a few starter pulses which follow each other in short succession and a plurality of control pulses which are always initiated as soon as the rotor of the stepper motor has turned by one stepping angle. In this particular fashion the acceleration of the stepper motor is accomplished with maximum dynamic torque.
