Magnetic suspension linear motor

Abstract

The invention provides a magnetic suspension linear motor, and can solve a problem of impact on the safety operation of the railway from a condition that a primary stator core of a conventional magnetic suspension linear motor is liable to be scratched by a cocked end of an aluminum plate on the surface of a rail. The linear motor comprises a primary part which is disposed at the bottom of a magnetic suspension train compartment and a secondary part which is laid on the surface of the rail. The primary part comprises a stator core and a plurality of winding coils which are embedded into the stator core. The secondary part extends in the length direction, and a plurality of aluminum plates laid on the surface of the rail are sequentially spliced. The stator core comprises a plurality of stator punch sheets, and the plurality of stator punch sheets are stacked, and are connected in a fastened manner through a locking bolt and a locking nut. The two end angles of the bottom length direction of the plurality of stator punch sheets are round angles or bevel angles. The plurality of stator punch sheets are stacked, and are fastened through the locking unit to form the stator core, wherein the two ends of the stator core in the bottom length direction are first arc end faces or inclined end faces.

Description

technical field [0001] The invention relates to the field of linear motors, in particular to the field of linear motors applied to magnetic levitation trains, in particular to a magnetic levitation linear motor. Background technique [0002] The maglev linear motor is an important driving device for maglev trains. It mainly includes the primary installed on the bottom of the train car and the secondary laid on the surface of the rail. The primary includes the stator core and the winding coil embedded in the stator core, and the secondary is along the length Extend in the direction and sequentially splice several sections of aluminum plates laid on the surface of the rail. After long-term operation of the train, the aluminum plates on the surface of the rail will inevitably warp at the joints due to the influence of external forces and other factors. Factors such as undulations, track flatness, and changes in train load will cause changes in the gap distance between the train...
