Abstract

The invention discloses a built-in hybrid excitation bilateral magnetic channel linear motor and relates to the technical field of linear motors. The linear motor includes a bilateral secondary stator and a primary mover arranged between the stators, the primary mover includes 6 primary mover units, there is a magnetic barrier between the primary mover units, and the mover The sub-unit includes two H-shaped magnetic cores, the bridge arms of the H-shaped magnetic cores are provided with built-in permanent magnets, and the two ends of the primary mover unit are respectively provided with two sets of armature winding installation slots and a A set of excitation winding installation slots; the secondary stator includes a stator yoke and secondary teeth; the bilateral secondary stator is a fixed part, the primary mover is a moving part, and the primary mover is made in the middle of the bilateral secondary stator Linear motion, which constitutes a linear motion motor with a double-sided plate structure. The linear motor has the advantages of low manufacturing cost, symmetrical flux linkage structure, small DC component, small harmonic component, high thrust density and the like.

Description

technical field [0001] The invention relates to the technical field of linear motors, in particular to a built-in hybrid excitation bilateral magnetic channel linear motor. Background technique [0002] Nowadays, with the development of industrial technology, linear motors are more and more frequently used in machine tool processing, numerical control, rail transit and other fields. Compared with traditional rotating motors, linear motors eliminate the need for mechanical transmission and directly generate electromagnetic force, which has inference density. Large, small loss, low noise and other advantages. [0003] As a research hotspot in the current linear motor industry, the flux switching permanent magnet linear motor has the advantages of simple structure and high reliability, but most of the existing flux switching motors have large positioning force, high material consumption rate, large DC component, The high harmonic distortion rate and other problems limit its ap...
