Description

Technical Field

[0001] This utility model relates to the field of stator processing technology, and in particular to a stator grinding device. Background Technology

[0002] The stator is the stationary part of an electric motor or generator. It consists of three parts: the stator core, the stator windings, and the frame. The main function of the stator is to generate a rotating magnetic field, while the main function of the rotor is to be cut by magnetic lines of force within this rotating magnetic field, thereby generating an electric current. The stator typically has a closed magnetic circuit design, and permanent magnets or excitation coils are usually mounted on the stator.

[0003] During stator manufacturing, after processes such as lamination and winding, burrs, flash, or impurities may remain on the surface. These defects can affect the performance and reliability of the motor. Grinding can effectively remove these burrs and impurities, ensuring the cleanliness and integrity of the stator surface. To prevent problems such as partial discharge and short circuits during motor operation, current stator grinding equipment has a low degree of automation, requiring manual operation for loading and unloading, wheel dressing, and parameter adjustment. This is not only labor-intensive but also prone to human error, affecting processing quality and production efficiency. Therefore, a stator grinding device is needed. Utility Model Content
