Abstract
The possibility and desirability of damping the step response of stepper motors has been noted by many authors. A root locus interpretation is presented in this paper which shows concisely some aspects of the damping. A method for providing damping when using a Pulsewidth Modulation (PWM) chopper is presented and it is shown to be possible to introduce damping in "single" or "multi"-phase excitation modes. These ideas have been implemented by the authors on three different stepper motors and some practical conclusions are presented.
