Why does the stator of an electric motor need to undergo the vacuum impregnation process?
- The vacuum impregnation process can make the insulating paint fully penetrate into the gaps and pores of the stator winding and iron core. This forms a continuous and dense insulating layer, effectively improving the insulation performance between the windings and between the windings and the iron core. It can prevent electrical breakdown and short circuits, and enhance the reliability and safety of the motor.
- By filling the gaps with insulating paint, the heat transfer path from the winding to the iron core and then to the outside of the motor is optimized. This improves the heat dissipation efficiency of the motor, preventing the motor from overheating during operation and prolonging its service life.
- The impregnated insulating paint can bond the stator windings and the iron core together, increasing their mechanical strength and stability. It can effectively reduce the vibration and noise of the motor during operation and improve the overall mechanical properties of the motor.
- The vacuum impregnation process forms a protective film on the surface of the stator, which can effectively prevent moisture, dust and other harmful substances from entering the inside of the stator, thereby reducing the risk of corrosion and deterioration of the winding and extending the service life of the motor.
