LPM Linear Motor

LPM04 Series

Designed with stator core to improve linear motor efficiency.

Due to less mechanical contact, linear motors have high response and long-term stability. High-speed dynamic response and higher speed have higher moving speed and positioning accuracy than the ball screw.
