Abstract

This paper describes the reduction of vibration and position error of Linear Pulse Motor(LPM) with the control method of PWM duty ratio by using Motion Controller in LPM. The LPM is operated on micro-stepping drive, that the linear scale is sequently returned the position signals of a micro-meter And next micro-step is controlled with the scale factor when position error is occurred. The scale factor is experimently acquired.
