Abstract

The invention discloses a stator permanent magnet mover iron core segmented linear oscillating motor and a unit group, which belong to the field of linear oscillating motors. The motor includes: a segmented mover iron core, including a plurality of separate mover irons core; stator core, including two parts that are symmetrically distributed on both sides of the moving plane of the segmented mover core, each part includes stator teeth and stator yoke; permanent magnet, surface-attached to the end of the stator core The surface of the stator teeth; the armature winding, including two sets of coils wound on the two stator teeth in the middle of the stator core; Generate sinusoidal electromagnetic thrust to push it to do reciprocating linear oscillation motion. The segmented mover iron core reduces the quality of the mover, improves the resonance frequency and power density of the system, and the surface of the permanent magnet is attached to the end teeth of the stator, which can avoid the installation of a permanent magnet sheath and reduce the mechanical air gap to strengthen the gap between the stator and the mover coupling, and is conducive to permanent magnet heat dissipation.

Description

technical field [0001] The invention belongs to the field of linear oscillating motors, and more particularly relates to a stator permanent magnet type mover iron core segmented linear oscillating motor and a unit group. Background technique [0002] Linear oscillation motors can be divided into linear asynchronous oscillation motors and linear synchronous oscillation motors according to whether there is a gap between the moving speed of the mover and the moving speed of the traveling wave magnetic field. Among them, linear synchronous oscillation motors usually only need single-phase windings, relying on electromagnetic force and resonant spring resonance to generate linear reciprocating motion strictly controlled by the input AC frequency, with performance advantages such as low loss, high efficiency, and large thrust. field is widely used. [0003] The moving iron linear synchronous oscillating motor generates alternating flux linkage by supplying alternating current to ...
