Precision microstepping system for bipolar stepper motor control

摘要

The paper presents a high performance system for stepper motor control in a microstepping mode, which was designed and performed with high-performed dedicated integrated circuits IXMS 150 PSI, made by IXYS SEMICONDUCTOR Company. The microstepping control system improves the positioning accuracy and eliminates low speed ripple and resonance effects in a stepper motor electrical drive. The same microstepping system is ideal for robotics, printers, plotters, X-Y tables and can facilitate the construction of very sophisticated positioning control system while significantly reducing component cost, board space design time and system cost. The same microstepping control system can be used for two single-phase DC motor’s, a variable reluctance motor’s and an AC biphasic motor’s control.
