Abstract

The invention discloses a secondary short magnetic circuit bilateral type primary permanent magnet type 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 pieces. U-shaped primary magnetic components, n armature windings and n permanent magnets, the primary magnetic components are arranged in a row, n permanent magnets are spaced between adjacent primary magnetic components, and the permanent magnets will be adjacent to the primary The teeth of the magnetically conductive parts are connected to form a magnetic pole, and the armature winding is wound on the magnetic pole; two sets of primary units are arranged oppositely; the secondary mechanism includes several secondary magnetically conductive parts, and all the secondary magnetically conductive parts are located in the two groups of primary The units are arranged in a staggered order along the direction of motor movement. 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 structure, and in particular relates to a secondary short magnetic circuit bilateral type 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, which improves the efficiency of the entire 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 magneti...
