3、 Thermal performance of insulation materials
The thermal properties of solid insulation materials, such as heat resistance and thermal conductivity, often play a major role in small and medium-sized motors. During the operation of the motor, it generates heat due to continuous energy consumption. Therefore, the insulation material inside the motor works in a hot state for a long time, causing it to gradually age and reduce or even completely lose its electrical and mechanical strength, resulting in damage to the motor. Therefore, the selection of insulation materials must have good heat resistance.
4、 Chemical and other properties of insulation materials
The stability and compatibility of insulation materials with environmental conditions can also become an important factor determining their performance and application in certain situations. If the motor is frequently operated, under complex conditions such as startup and acceleration, the operating environment of the motor is harsh, and the dynamic working conditions are complex, mainly reflected in high temperature, vibration, and strong corrosion. Therefore, it is required that the insulation materials used for the motor have high antioxidant and corrosion resistance under harsh conditions such as high temperature and humid heat. The resistance of insulation to electrolysis is also very important under the action of low-frequency DC voltage.
