Problems solved by technology

[0003] However, due to the mechanical friction and wear between the stator and the mover of the traditional linear motor, the excellent performance of the ordinary linear motor is limited. The magnetic levitation linear motor uses the magnetic levitation technology to realize the non-contact support of the mover suspension, and the mover and the stator are always in contact with each other. Maintain a certain air gap, eliminate the frictional resistance between the stator and the mover, and greatly improve the sensitivity, speed and follow-up of the system

Abstract

The invention discloses a square dual-stator hybrid reluctance type magnetic levitation linear motor, which comprises an upper stator, a lower stator and a mover. Pressed, each sheet stator from left to right is: left suspension core, left stator bypass core, left axial control core, right axial control core, right stator bypass core, right suspension core, left and right suspension The iron core, the left and right bypass iron cores are connected as a whole through an axially magnetized permanent magnet block, and then connected with the left and right axial control iron cores through a magnetic isolation aluminum block. The positioning is accurate and the action is fast. When the mover is in the equilibrium position , the mover is kept in stable suspension by the bias magnetic flux, and the power consumption of the motor is low.

Description

technical field [0001] The invention relates to a square dual-stator hybrid reluctance type magnetic levitation linear motor with no friction and wear, simple control, reliable operation, strong load capacity, fast response speed, accurate positioning and low power consumption, belonging to the technical field of motor manufacturing . Background technique [0002] With the rapid development of automatic control technology and microcomputers, higher requirements are placed on the positioning accuracy of the linear motion control system. The linear motion drive device composed of a traditional rotating motor and a set of transformation mechanisms has been difficult to meet the requirements of modern linear motion control. The performance requirements of the system, the direct drive of the linear motion load by the linear motor has the following advantages: ①. The structure is simple, because the linear vibration motor does not need additional devices to convert the rotary moti...
