A split stator moving iron core permanent magnet linear oscillating motor

Abstract

The invention provides a stator split type moving iron core permanent magnet linear oscillation motor, which belongs to the field of linear oscillation motors. The outer stator core is symmetrically distributed on both sides of the inner stator permanent magnet; the mover core is symmetrically distributed at equal intervals. Between the outer stator core and the inner stator permanent magnet; the resonant spring is set on the motion axis; the motion axis is connected at the geometric center of the edge of the mover core bracket; the armature winding includes two sets of coils, which are connected to a sine wave during use AC source; the internal stator permanent magnets include several sub-permanent magnets of equal size, the magnetizing directions are all vertical, and the magnetizing directions of adjacent sub-permanent magnets on the horizontal side are different from each other; when the magnetizing directions of adjacent sub-permanent magnets on the vertical side are opposite When the inner stator iron core is added between the two pole permanent magnets, the two sets of coils are connected in reverse series or in reverse parallel. On the contrary, the two sets of coils are connected in series or in parallel in the same direction; the invention extends 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 are reduced.

Description

Technical field [0001] The invention belongs to the field of linear oscillation motors, and more specifically, relates to a stator-split moving iron core permanent magnet linear oscillation motor. Background technique [0002] The traditional way of realizing bidirectional linear reciprocating motion in air compressors is as follows: the rotating 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 motor efficiency, and the other is to improve the transmission efficiency. However, due to the presence of multiple intermediate links, the overall efficiency of the compressor is still low. 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 becom...
