Selection of motor insulation paper

1. Insulation performance: The main function of insulation paper is to provide electrical insulation protection, so the insulation performance of insulation paper is one of the important criteria for selection. The dielectric strength and dielectric loss of insulation paper are indicators for evaluating insulation performance. Generally speaking, hard insulation paper can be selected when the dielectric strength is high, and soft insulation paper can be selected when the dielectric loss is high.

2. Mechanical properties: The motor may be affected by vibration, impact, etc. during operation, so the mechanical properties of insulation paper are also very important. Mechanical properties include tensile strength, folding strength, tear strength and other indicators, which can ensure that the insulation paper is not easy to break or deform, thereby improving the reliability and life of the motor.

3. Thermal stability: The motor will generate a higher temperature when working, so the thermal stability of insulation paper is also an important consideration when selecting. Thermal stability refers to the stability of insulation paper at high temperature. Generally, insulation paper is required to maintain its insulation and mechanical properties unaffected in a high temperature environment.

4. Chemical resistance: The motor may be exposed to some chemicals, such as oil, water, etc., so the chemical resistance of insulation paper also needs to be considered. Oil resistance, water resistance and corrosion resistance are indicators for evaluating the chemical resistance of insulating paper.

In summary, choosing suitable motor insulating paper requires comprehensive consideration of factors such as insulation performance, mechanical properties, thermal stability and chemical resistance, and selection based on specific uses and requirements.
