After the motor becomes damp, many problems gradually appear and are solved. This is because moisture enters the winding material of the core component of the motor. To solve the problem, the winding needs to be dried. Since it is dry, the heating process is definitely indispensable. After the motor is heated, the moisture in the internal winding insulation material will be dried, improving its moisture resistance.
After heating, the winding needs to be immersed in paint. The immersed insulation paint can fill all gaps between the insulation of the winding material and the wire, preventing moisture from entering, thereby enhancing the electrical insulation strength of the winding. At the same time, the heat from the winding can also be dissipated through the insulation paint and the iron core to the casing, so that the motor will not experience excessive temperature rise.
The winding treated with impregnation has another advantage, as the wires will be bonded into a solid whole due to impregnation, reducing the possibility of damage. The above can not only solve the impact of moisture on the motor, but also be the reasons for the impregnation treatment of the motor winding.
