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

2. Mechanical properties: The motor may be subject to vibration and impact when working, so the mechanical properties of the insulating paper are also very important. Mechanical properties include tensile strength, folding strength, tearing strength and other indicators, which can ensure that the insulation paper is not easy to break and deform, thereby improving the reliability and life of the motor.

3. Thermal stability: The motor will generate higher temperatures when working, so the thermal stability of the insulating paper is also an important consideration in the selctrion. Thermal stability refers to the stability of insulating paper at high temperatures. Insulating paper is generally required to maintain its insulation and mechanical properties without being affected in high temperature enviornments.
