BorgWarner has begun manufacturing eMotor rotors and stators for XPeng Motors, a renowned Chinese smart EV manufacturer. The product will be utilised on both the X9 MPV and XPeng’s future electric B-class car, with manufacturing beginning in Q3 2024.
According to BorgWarner, the high voltage hairpin (HVH) 220 eMotor provides great power and torque density, as well as improved efficiency, all at a competitive price. It also offers exceptional durability.
Stefan Demmerle, President and General Manager, BorgWarner PowerDrive Systems, said, “We are excited to supply this leading OEM with our proven stator and rotor, boosting the development of China’s electric vehicle industry. BorgWarner’s in-depth product expertise will support XPeng as they progress in designing their electric drives.”
The HVH220 eMotor has an operating range of up to 800V, using a stator with an outer diameter of 220 mm and BorgWarner’s patented high voltage hairpin winding technology. It incorporates permanent magnet rotor and proprietary stator insulation enhancement technologies, providing premium durability and reliability. BorgWarner’s HVH220 can produce up to 300kW in power with a maximum working speed of 18,000 rpm, with peak efficiencies greater than 97 percent.
BorgWarner has developed oil-cooled solutions to meet the performance demands of higher-powered motors. Specifically, the gearbox oil cools the motor, improving heat transfer and total heat rejection of the system. Direct rotor oil cooling also extracts heat from the electric motor core, enabling higher torque and power density to be achieved.
