Problems solved by technology

The current technology is difficult to overcome the interference of the cable drag disturbance force brought by the moving cable, which affects the servo positioning performance. The drag chain bracket of the mover and the load cable also makes the life of the moving system not high, and the fault reliability problem is frequent. send
[0005] In addition, due to the existence of cables, it is difficult for the traditional linear motor drive technology to realize the circular servo motion of multiple moving subunits on the production line with large strokes at the same time

Abstract

The invention relates to a linear motor, a linear motor module and a rotor thereof. The rotor is provided with a base; an auxiliary supporting plate is mounted on the base; back iron is mounted on the auxiliary supporting plate; a back iron supporting plate is arranged between the back irons; the back iron and the back iron supporting plate jointly form a U-shaped structure; a permanent magnet array is arranged on the back iron; and the permanent magnet array is arranged into a Halbach array. The linear motor, the linear motor module and the rotor of the linear motor are compact in structure, large in thrust and high in reliability.

Description

technical field [0001] The invention belongs to the technical field of linear motors, and in particular relates to a linear motor, a linear motor module and a mover thereof. Background technique [0002] With the development of manufacturing technology in the direction of high productivity and high precision, the research on precision motion control technology is becoming more and more important. Correspondingly, the demand for motion positioning control system is also increasing, which is widely used in automated production lines, packaging and Transportation, assembly automation, screen printing and other industries provide higher speed and processing flexibility. The traditional drive system adopts a rotary motor drive structure, and the gear heads, shafts, keys, sprocket teeth, chains, belts and other components commonly used in traditional rotary motor transmission in the transmission system are very complicated and heavy. Linear motors apply a moving magnetic field to...
