Silicon steel sheet paint
Silicon steel sheet is also the main raw material of the motor. Silicon steel sheet paint is used to coat silicon steel sheet to reduce the eddy current loss of the core and enhance the corrosion resistance. After the silicon steel sheet paint is applied, it needs to be dried at a high temperature for a short time. It is characterized by thin layers, strong adhesion, hardness, smoothness, uniform thickness, oil resistance, moisture resistance and good electrical performance.
Anti-corona paint
Corona discharge is a discharge phenomenon in which a localized air is ionized to generate a blue halo in a highly inhomogeneous electric field.
Anti-corona paint is generally made of insulating varnish and non-metallic conductor (carbon black, graphite, etc.) powder, mainly used for anti-corona paint of high-voltage coil, such as the coil end of high voltage in large high-voltage motor. Many motor manufacturers apply anti-corona paint on the surface of the stator and rotor and the rotor after spraying.
