BorgWarner starts motor production for XPeng

February 12, 2024

BorgWarner has initiated the production of eMotor rotor and stator for XPeng Motors, a prominent Chinese EV maker.

The product will be incorporated into the X9 MPV and XPeng’s forthcoming electric B-class sedan, with production set to commence in Q3 2024.

They will produce the high voltage hairpin motor (the HVH220 eMotor) which operates at a range of up to 800V, featuring a stator with an outer diameter of 220 mm and BorgWarner’s patented high voltage hairpin winding technology. The eMotor integrates a permanent magnet rotor and proprietary stator insulation enhancement technologies, ensuring premium durability and reliability. The HVH220 can generate up to 300kW in power with a maximum working speed of 18,000 rpm, and peak efficiencies exceeding 97%.

To meet the performance demands of higher-powered motors, BorgWarner has devised oil-cooled solutions. Specifically, the motor is cooled by the gearbox oil, which enhances 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.

BorgWarner’s HVH220 is available in various stack lengths, cooling and winding configurations, either as a cartridge assembly or a fully housed eMotor.
