Application of Linear Motor in Precision Machining

Compared with traditional ball screw driving, linear motor features rapid response, higher instantaneons acceleration and deceleration (up to 1-6g), wider frequency response range and higher movement resolution. It has been used on modern NC machine tools. In this paper, the principle, features and working characters of linear motor are introduced performance test and control method of inductance linear motor are illusttraied. The paper also introduces the application of linear motor in precise grinding.
