BorgWarner announces additional eMotor business

The company says its HVH220 eMotor offers high power and torque density, enhanced efficiency and durability.

BorgWarner secured two high-voltage hairpin (HVH) eMotor business contracts with XPeng, a Chinese smart EV manufacturer, for use on two upcoming SUV models. The contracts include BorgWarner’s oil-cooled 800V eMotor systems, comprising stator and rotor components customized for the vehicles. Production is planned to start in 2025. BorgWarner says its HVH220 eMotor offers high power and torque density, enhanced efficiency and durability.

“We are thrilled to expand our eMotor business with XPeng and build upon our years-long partnership with them,” said Dr. Stefan Demmerle, president and general manager of BorgWarner PowerDrive Systems. “As we continuously evolve our HVH technology, we are dedicated to delivering maximum efficiency for our customer’s two future SUV models.”

The HVH220 eMotor, featuring BorgWarner’s high-voltage hairpin winding technology, operates within an 800V propulsion system. With a stator outer diameter of 220 mm, this motor solution integrates a permanent magnet rotor and proprietary stator insulation enhancements. Capable of generating up to 300kW of power and reaching a maximum speed of 18,000 rpm, BorgWarner’s HVH220 achieves peak efficiencies exceeding 97%, the company said.

Addressing the need for enhanced performance in high-power motors, BorgWarner said it engineered oil-cooled solutions. By utilizing gearbox oil to cool the motor, this technology optimizes heat transfer and overall thermal management efficiency. Additionally, direct rotor oil cooling efficiently extracts heat from the electric motor core, facilitating higher torque and power density.
