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 comprises bilateral secondary stators and a primary mover arranged between the stators. The primary mover comprises six primary mover units, and magnetic barriers exist between the primary mover units. Each mover unit comprises two H-shaped magnetic conductive iron cores, and built-in permanent magnets are arranged at the bridge arm positions of the H-shaped magnetic conductive iron cores. Two groups of armature winding mounting grooves and one group of excitation winding mounting grooves are respectively formed in the two ends of the primary mover unit. Each secondary stator comprises a stator yoke and secondary teeth. The bilateral secondary stators are fixed parts, the primary mover is a moving part, and the primary mover performs linear motion in the middle of the bilateral secondary stators, so that the linear motion motor with a bilateral flat plate structure is formed. The linear motor has the advantages of being low in manufacturing cost, symmetrical in flux linkage structure, small in direct current component, small in harmonic component, large in 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...
