Abstract

A multi-layer winding magnetic suspension linear permanent magnet synchronous motor belongs to the field of motors. The invention aims at the problems of serious coupling between the suspension force and the electromagnetic thrust force of the existing magnetic suspension linear motor and difficult control. It is mainly composed of primary and secondary, and the air gap between the primary and secondary is horizontal; the primary is mainly composed of the primary substrate, the propulsion winding and the suspension winding; the secondary is a bilateral secondary structure, and each secondary is composed of a yoke plate and It is composed of permanent magnets, and the permanent magnets are alternately arranged and fixed on the yoke plate along the moving directions N and S in turn; the magnetizing directions of the permanent magnets at the corresponding positions on the two secondary parts are opposite. The invention can realize the decoupling control of the electromagnetic thrust and the levitation force.

Description

technical field [0001] The invention relates to a multi-layer winding magnetic suspension linear permanent magnet synchronous motor, which belongs to the field of motors. Background technique [0002] Modern precision and ultra-precision machining equipment has an urgent need for high-response, high-speed, high-precision linear motor servo systems, such as machining, electronic product production, mechanical loading and unloading, manufacturing automated instrumentation equipment and even robot drives. [0003] At present, the support methods of the mover of the linear motor servo system mainly include mechanical support, air suspension support and magnetic suspension support. The magnetic suspension support relies on electromagnetic force to support the linear motor mover. There is no mechanical contact between the linear motor stator and the mover, and the mover can achieve high running speed and support accuracy. Compared with the traditional machine tool guide rail, the...
