Abstract

The invention discloses a hybrid reluctance type magnetically levitated linear motor with axial biased magnetic flux. An upper stator comprises a suspended iron core with an inverted U-shaped front-view projection and M-shaped left-side-view projection and right-side-view projection; suspended windings are wound on three vertical teeth of M-shaped structures on the left and right sides; an axiallymagnetized permanent magnet with opposite magnetic poles is interposed between the adjacent vertical teeth; a control iron core with an inverted U-shaped front-view projection and M-shaped left-side-view projection and right-side-view projection is arranged between two vertical rods of the front-view projection of the suspended iron core; and axial control windings are wound on the three verticalteeth of the M-shaped structures on the left side and right side. According to the hybrid reluctance type magnetically levitated linear motor with the axial biased magnetic flux provided by the invention, the magnetic resistance generated by electrifying the axial control windings in turn is used for realizing the axial linear movement of a rotor; the suspension control and the axial motion control are completely independent, thus the control is simple and the implementation is easy; and when the rotor is in a balance position, stable suspension of the rotor is achieved through the biased magnetic flux, and the power consumption is extremely low.

Description

technical field [0001] The invention belongs to the technical field of motor manufacturing, and specifically relates to a hybrid motor with axial bias magnetic flux, which has no friction and wear, simple control, reliable operation, strong load capacity, fast response speed, accurate positioning and low power consumption. Reluctance type magnetic levitation linear motor. 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 additio...
