Abstract

The invention discloses a bilateral primary permanent magnet transverse flux linear motor, which includes a primary mechanism and a secondary mechanism. The primary mechanism includes two sets of primary units with the same structure, and each primary unit includes n+1 U-shaped primary magnetic conductors. Components, n armature windings and n permanent magnets, n+1 primary magnetic conductive parts are arranged in a row in sequence, n permanent magnets connect adjacent teeth of adjacent primary magnetic conductive parts to form a magnetic pole, magnetic pole The armature winding is wound on top; two sets of primary units are arranged oppositely; the secondary mechanism includes several secondary magnetically conductive parts, and each secondary magnetically conductive part includes a yoke and 2n+2 teeth symmetrically arranged on both sides of the yoke The two groups of primary units are respectively located on both sides of the secondary magnetically permeable part. This kind of linear motor can realize the permanent magnet and winding on the primary side at the same time and each phase is isolated and decoupled, the electromagnetics are independent of each other, the torque density is high, the design is flexible, the control is convenient, and the secondary side structure is simple and reliable.

Description

technical field [0001] The invention belongs to the technical field of motor design, in particular to a double-sided primary permanent magnet transverse flux linear motor. Background technique [0002] When the linear motor drives the linear motion load, the conversion mechanism from the rotation to the linear motion of the rotary motor is omitted, so it has the advantages of simple overall structure, high position accuracy, fast response speed, and low noise. Improve the efficiency of the whole system. In recent years, with the application of linear drives more and more widely, linear motors have gradually become one of the hot spots of research and development, and have been widely used in military industry, aerospace, rail transportation, electromagnetic ejection and other fields. [0003] The motion direction of the transverse flux linear permanent magnet motor is perpendicular to the plane where the motor magnetic field path is located. The motor circuit and the motor ...
