HOLLOW-SHAFT LINEAR MOTOR

摘要

Disclosed is a hollow-shaft linear motor, comprising a shaft lever (1), a motor casing (2), and a rotor and a stator which are arranged in the motor casing; the rotor is in an electromagnetic fit with the stator; the shaft lever and the stator are linked and are retracted in the movement direction of the rotor; and the shaft lever penetrates through the motor casing and extends from two ends of the motor casing. The shaft lever is internally provided with a through hole (11) for connecting an external pipe fitting (6) in a penetrative manner, and the through hole extends in the axial direction of the shaft lever. The motor can be conveniently and smoothly connected to the pipe fitting in a penetrative manner and linked with the pipe fitting, so as to prevent friction from interfering with the pipe fitting.
