2상 하이브리드형 스텝 모터의 미세스텝구동에 관한 연구

A study on a microstepping drive for 2 phase hybrid-type step motors

In this paper we addressed the basic concept of microstepping, analyzed the combined effect of the motor detent torque and the current profile, and implemented a microstepping drive system using an one-chip microprocessor, power MOSFET's, and a 1.8 degree bifilar-wound hybrid-type step motor excited by a bipolar drive. Experimental results show that microstepping produces greater resolution, eliminates resonant step loss, and reduces motor vibrations.
