AI Technical Summary

Problems solved by technology

[0002] Various rotators in engineering, due to various factors such as uneven material or blank defects, errors in processing and assembly, and even asymmetrical geometric shapes in design, make the rotator rotate. The centrifugal inertial force generated by tiny particles cannot cancel each other out. The centrifugal inertial force acts on the machine and its foundation through the bearing, causing vibration, generating noise, accelerating bearing wear, shortening the life of the machine, and causing destructive accidents in serious cases.

[0003] When assembling traditional motors, special fixtures are usually used to fix the motor casing, and then the motor rotor is assembled. Although the fixtures can ensure the stability of the motor casing to a certain extent, it is difficult for motor casings of different specifications and sizes. Ensuring that the same fixture can be adapted will undoubtedly reduce production efficiency. In addition, since the silicon steel sheets of the motor stator and rotor will attract each other due to magnetism, if there is a deviation during the assembly process, the assembly of the motor stator and rotor will be difficult. Cause damage to the rotor, and the rotor needs to be tested after assembly to ensure stable use
