BorgWarner, a provider of mobility solutions for the vehicle market, has been selected to provide high-voltage hairpin (HVH) e-motors for a leading electric vehicle brand in China.

The e-motors will be used in the unnamed company’s second-generation 800V propulsion system platform. The vehicle model equipped with this platform is expected to start mass production in October 2023.

“We are excited to continue our partnership with this Chinese leader in EVs, working together to succeed in the Battery Electric Vehicle sector,” said Dr Stefan Demmerle, President and General Manager, BorgWarner PowerDrive Systems. “BorgWarner’s e-motors feature premium reliability, higher efficiency as well as superior power and torque density, and exemplify our extensive experience in e-mobility applications.”

The 800V oil-cooled e-motors from BorgWarner are available as either motor assemblies or stator and rotor subassemblies. They incorporate built-in, permanent magnet rotor and proprietary stator insulation enhancement technologies, providing premium durability and reliability. They deliver peak efficiency of over 96% and feature patented HVH stator winding technology. In addition, the motor operates with energy efficiency and environmental friendliness with excellent noise, vibration and harshness (NVH) performance, and up to 4% higher power and torque density compared to other products of its breed. During vehicle braking and downhill, the motor can also convert mechanical energy into electrical energy and charge the battery through the inverter.
