CLOSED-LOOP, CONTROL SYSTEM FOR A STEPPING MOTOR

摘要

Abstract of the DisclosureA system and method for operating a steppingmotor in start, run, and stop modes of operation.After the stepping motor is accelerated in the startmode, it is operated in the run mode by energizing thewindings with a lead angle of two steps in oneembodiment and by energizing the windings with a leadangle of two and one quarter steps in a secondembodiment.
