混合式步进电动机SPWM微步驱动技术

STUDY ON FIVE-PHASE HYBID STEPPING MOTOR MICROSTEPPING DRIVER SYSTEM WITH SPWM TECHNIQUE

对电流跟踪型SPWM技术应用于五相混合式步进电动机微步驱动系统中的若干理论进行了系统分析 。

The microstepping drive technique can improve the dynamic performance and the position resoiution.The theories in the fiver phase hybrid motor microstepping drive system with fixed hysteresis band current controlled SPWM technique are analyzied .A few conclusions which give theoritical references in making the system are put forward.
