[0002] Grinding is a type of surface modification technology.

The main purpose is to obtain a specific surface roughness.

[0003] An electric motor (commonly known as a "motor") is an electromagnetic device that realizes the conversion or transmission of electric energy based on the law of electromagnetic induction. The stator core is an important component of the stator and the main component of the motor's magnetic circuit. It is composed of fan-shaped sheets, ventilation slot sheets, positioning ribs, upper and lower tooth pressure plates, tensioning bolts and support plates. The stator core is punched into fan-shaped sheets with silicon steel sheets and stacked on the positioning ribs. The positioning ribs are welded to the base ring plate through the support plate, and the core is tightened into a whole through the upper and lower tooth pressure plates with tensioning bolts. The core is also the part where the winding is placed. When the generator is running, the core will be subjected to the combined effects of mechanical force, thermal stress and electromagnetic force.
