[0002] Powder metallurgy is a process technology that produces metal powder or uses metal powder (or a mixture of metal powder and non-metallic powder) as raw material, and then forms and sinters it to manufacture metal materials, composite materials and various types of products. Powder metallurgy is similar to the production of ceramics, both of which belong to powder sintering technology. Therefore, a series of new powder metallurgy technologies can also be used in the preparation of ceramic materials.

The stator is used to generate a rotating magnetic field. The stator consists of the frame, the stator core, the coil and other structural parts that fix these parts. The frame is used to fix the core. For suspended generators, the frame is used to bear the entire weight of the rotating part. The core is part of the generator's magnetic circuit; the coil forms the generator's circuit.

[0004] The existing motor stator has poor structural strength, which may cause the stator to be damaged after being used for a period of time.
