Abstract

The invention discloses a reluctance magnetic suspension linear motor, comprising an upper stator, a lower stator and a rotor. Side-looking projections of an upper left suspension iron core and an upper right suspension iron core are U-shaped structures. First suspension windings and sixth suspension windings are respectively wound on U-shaped teeth of the upper left suspension iron core and the upper right suspension iron core. The side-looking projections of an upper left control iron core and an upper right control iron core are E-shaped structures. Third axial control windings and fourth axial control windings are respectively wound on E-shaped teeth of the upper left control iron core and the upper right control iron core. The rotor comprises a left suction disk, a right suction disk,M axially arranged left rotor teeth, and M axially arranged right rotor teeth. The rotor contactless suspension support is realized, and the sensitivity, rapidity and servo performance of a system are greatly improved. The contactless transmitting ability of the magnetic suspension linear motor is realized, the mechanical friction loss is almost zero, all faults are few, the maintenance is avoided, the work is safe and reliable, and the service life is long.

Description

technical field [0001] The invention relates to the technical field of motor manufacturing, in particular to a reluctance type magnetic levitation linear motor with no friction and wear, simple control, reliable operation, strong load capacity, fast response speed and accurate positioning. Background technique [0002] With the rapid development of automatic control technology and microcomputers, higher requirements are placed on the positioning accuracy of linear motion control systems. 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 systems. Performance requirements, 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 motion into a linear motion, so the structure of the system itse...
