Abstract
A linear motor is provided. The linear motor includes an output shaft, a stator sleeved outside the output shaft, a rotor sleeved outside the output shaft and in screw-thread fit with the output shaft, and a brake unit sleeved outside the output shaft. The rotor is coupled with the stator and is driven to rotate by an electromagnetic force generated between the rotor and the stator, thereby driving the output shaft to move axially. Through screw-thread fit between the rotor and the output shaft, the linear motor is conducive to reducing the radial dimension, the output shaft may move smoothly with low noise and large output power, higher control precision may be obtained. When the brake unit is sleeved outside the output shaft, a circumferential space on the periphery of the output shaft may be fully utilized to arrange the brake unit, braking on the output shaft is stable.
