(Summary description)With the development of new energy vehicles, motors, as the core drive systems of new energy vehicles, face harsh working conditions and changes in non-viral air tightness, which affect the performance of the entire vehicle. 1. Use high temperature resistant materials to cope with harsh working conditions; 2. Pressure relief and ventilation, release the air pressure generated by changes in motor working conditions, to avoid damage to precision components; 3. Dustproof, reduce condensation, and balance the pressure (stress) inside and outside the motor cavity; 4. The excellent design structure solves the safety problems caused by the sudden increase of internal pressure during the work of the electric drive; 5. Realize customization and diversified designs to meet customer needs. Motor application Puwei protective venting products: 1. PUW Puwei provides protective venting products for many automobile motor manufacturers and vehicle manufacturers. The products have been strictly tested by automobile motor manufacturers and the vehicle manufacturers have been trained in harsh environments. Practice has proved that the quality is reliable and durable. 2. PUW Puwei matches different solutions according to the focus of the application environment of auto parts.
