GUIDE RAIL FOR AN ELECTRIC ACTUATOR

摘要

A motor is integrally mounted on one end of a ball screw over which an engaging block is threaded, and an encoder is integrally mounted on the other end of the ball screw for detecting the rotational speed or angular displacement of the motor. The motor, the ball screw, and the encoder are combined into a unitized assembly as a drive unit. The motor and the encoder are positioned on respective steps of a frame, and detachably fastened to the frame.
