Problems solved by technology

[0004] In the above magnetic steel fixing structure, the radial positioning of the magnetic steel 13 needs to be provided with threaded holes on the circumferential side wall of the rotor core 12. Increase the process of opening threaded holes, resulting in more complicated production of the entire rotor and lower production efficiency
[0005] In addition, opening threaded holes inward from the outer circular surface of the rotor core 12 is more difficult to process, and it is easier to damage the rotor magnetic circuit structure.

Abstract

The present invention relates to a rotor, a magnet steel fixing structure thereof, and a motor. The motor magnet steel fixing structure includes a rotor core, magnet steels sequentially distributed in the circumferential direction of the rotor core, and stoppers located between two adjacent magnet steels, wherein each stopper includes a connecting portion and two pressing plates both fixedly connected with the connecting portion, the two pressing plates are respectively pressed on two adjacent magnet steels, and the connecting portion is in positioning connection with the rotor core in a radial direction through a concave-convex cooperative structure. In the magnet steel fixing structure, the connecting portion is in positioning connection with the rotor core in a radial direction through a concave-convex cooperative structure, and the structure required by the concave-convex cooperative structure can be formed in a rotor core punching process, so that compared with the prior art, a processing flow is reduced, the rotor core production process is simplified, thereby the production of a whole rotor is simplified, and rotor production efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of permanent magnet motors, and more specifically, relates to a rotor, a magnetic steel fixing structure thereof, and a motor. Background technique [0002] At present, permanent magnet motors usually use adhesives such as glue to directly paste the magnetic steel on the surface of the rotor core. Adhesives often contain toxic substances, which can cause harm to the human body if exposed to them for a long time; secondly, manual operation is often used to paste magnets, and the thickness of glue application cannot be guaranteed to be uniform. The product consistency and reliability are poor, and the application thickness is uneven, which directly affects The gap between the stator and the rotor affects the performance of the motor; in addition, the adhesive needs to be kept at a certain temperature for a long time before it can be cured, and the manufacturing efficiency is low. [0003] In order to reduce t...
