Development and Implementation of AC Servo Motion System

摘要

After reviewing the development of servo motor in China, the concept of ac servo motion system is put forward and introduced in this paper. Then the control structure of ac servo motion system is divided and compared. In order to speed up the development of sinusoidal-current-excited permanent magnetic synchronous motor (PMSM) servo system, the technology routine suitable to China is explored and the research emphasises are presented. Finally a design example of PMSM servo motion system is given.
