A split stator moving iron core permanent magnet linear oscillating motor

Abstract

The invention provides a stator split moving iron core type permanent magnet linear oscillating motor, which belongs to the field of linear oscillating motors, wherein the outer stator iron cores are symmetrically distributed on both sides of the inner stator permanent magnets; the movable iron cores are symmetrically distributed at equal intervals Between the outer stator core and the inner stator permanent magnet; the resonant spring is sleeved on the movement shaft; the movement shaft is connected to the geometric center of the side end of the mover iron core support; the armature winding includes two sets of coils, which are connected by a sinusoidal AC source; the inner stator permanent magnet includes several sub-permanent magnets of equal size, and the magnetization directions are all vertical directions, and the magnetization directions of adjacent sub-permanent magnets on the horizontal side are different; when the magnetization directions of adjacent sub-permanent magnets on the vertical side are opposite When the inner stator core is added between the permanent magnets of the two poles, the two sets of coils are connected in reverse series or reverse parallel; otherwise, the two sets of coils are connected in series or parallel in the same direction; the present invention prolongs the service life of the permanent magnets, and at the same time The output thrust density is improved, and the noise and vibration of the motor operation are reduced.

Description

technical field [0001] The invention belongs to the field of linear oscillating motors, and more particularly relates to a stator split type moving iron core type permanent magnet linear oscillating motor. Background technique [0002] The traditional implementation of bidirectional linear reciprocating motion such as air compressors is that the rotary motor converts the circular motion into linear motion through the crank connecting rod, thereby driving the piston motion. There are two main ways to improve the efficiency of this compressor: one is to improve the efficiency of the motor, and the other is to improve the transmission efficiency. However, the overall compressor efficiency is still low due to the existence of multiple intermediate links. At the same time, the traditional rotary compressor structure also has many other defects, mainly reflected in the complex structure, large volume, high noise and low efficiency. Permanent magnet linear oscillation motors have...
