Solvent-free insulating paint for motors
● Solvent-free insulating varnish can better fill the gap of the coil and stabilize and insulate. We know that the thinner is a volatile matter, and only the solid content component can be left. Therefore, the solid content is an important performance index of the insulating varnish.
● Motor solvent-free insulating varnish is well tolerated. For example, temperature resistance, for different heat resistance grades, the heat resistance grade of the insulation material is required to meet the requirements, and one of the insulation paints is a very important factor. The withstand voltage index refers to its breakdown resistance or dielectric strength, which also has a significant impact on the reliability of the motor; the adhesion of the insulating paint refers to its adsorption force, and the product impregnated with the insulating paint allows the product to be integrated into one. It is difficult or impossible to be separated and loosened by high-speed rotating external force, which has a great influence on the vibration and temperature rise performance of the motor product.
The requirements for environmental protection are an important requirement under the current production requirements, and are important factors affecting the environment and employee health. Therefore, non-toxic, low temperature, and through the international ROHS standards have become the choice of motor manufacturers. Consider the indicator.
● Motor insulation paint life. During the normal life cycle of the motor, the insulating paint should not undergo a qualitative change and should not affect the performance of the motor. The normal use period of the motor solvent-free insulating varnish is about 20-25 years, which means that the motor life is between 20-25.
●Good heat dissipation and strong permeability. This is a must for the performance of the motor and is also a requirement for the motor production cycle.
