Application of BMC Material in Motor
In the past, when the motor was produced, the motor had to use the metal shell protection, the internal coil impregnation insulation and so on. The production process was complicated because of the technical requirements of heat resistance, heat dissipation, electrical insulation and impact resistance. And this kind of motor weight, serious noise, insulation is not ideal. Now the use of high thermal conductivity, good heat dissipation, but also insulated special BMC composite material on the motor stator plastic, you can not need metal shell protection, do not need to immerse the coil insulation. Coupled with the BMC damping large, high frequency, to avoid the motor when the noise generated by the resonance point, the motor without voice, production costs reduced by 30%. Therefore, it can be said that the application of BMC in the motor for the production of ultra-quiet household appliances to provide a strong material guarantee. So the recent import from China's domestic air-conditioning, refrigerators have all use such motor. BMC material contains a lot of glass fiber, so its mechanical strength is greater than the general thermoplastic engineering plastics. Can be hot and humid, cold, corrosive environment in the long-term use. According to the different performance requirements of electrical products, through the regulation can be made into a variety of performance BMC molding compound. BMC such as excellent electrical insulation, electrical conductivity, antistatic properties, thermal insulation, thermal conductivity, flame resistance, arc resistance, resistance to leakage, chemical resistance, electromagnetic shielding ... ... and so on. Moreover, unlike phenolic bakelite, BMC can also be made according to the needs of a variety of brightly colored products. BMC heat resistance is better than general engineering plastics. Long-term heat-resistant temperature of 130 ℃. BMC water absorption at the end of 24 hours after immersion, insulation performance is still very good, can guarantee the use of heat and humidity conditions. BMC after the contraction is zero, the workpiece size is stable, so with many thermosetting plastics and thermoplastic engineering plastics, BMC is more suitable for the production of precision parts. BMC also has the function of attenuating and eliminating micro-vibration and vibration-shaking, so it can be used in electric car seat motor, wiper motor, window motor and so on.
