Generally speaking, the silicon steel sheets of the stator itself have an insulating coating. As long as it is not in a special environment, the inter – layer is not easily corroded. However, on the punching and shearing surfaces of the stator and rotor, since Fe directly reacts with the air, if anti – rust treatment is not carried out immediately after punching, the iron core generally will rust to varying degrees within 1 – 2 weeks. But even if anti – rust treatment is adopted, if the motor’s working environment is relatively humid or there is water mist, such as the motor of a plant protection machine, then special anti – rust treatment needs to be carried out for the product; we also call it electrophoretic spraying.
