Description
Technical Field

[0002] Permanent magnet synchronous motors usually include a motor housing, front and rear end covers, front and rear bearing inner and outer covers, a stator, and a rotor. During electrical assembly, the rotor needs to be installed in the stator, and the hollow shaft needs to pass through the end covers and the inner and outer bearing covers. Since the distance between the stator and the rotor is very close, and the magnetism of the magnetic steel is very strong, it will adsorb the silicon steel sheet of the stator. As a result, during the assembly process, it is difficult to ensure that the center of the shaft and the center of the end cover are in the same straight line. Manual positioning is prone to positioning deviation during the press-fitting of the end cover, which will cause damage to the motor body or end cover after press-fitting, which will affect the normal use of the motor. Therefore, a motor disassembly and assembly combined tooling is required. Utility Model Content
