BorgWarner launches 800 V motor for commercial vehicles

By Mike Brezonick10 February 2021

BorgWarner has launched the newest model in its High Voltage Hairpin (HVH) electric motor range, the HVH 320, which incorporates four 800 V variants with outputs to over 400 kW (536 hp).

BorgWarner, the Michigan-based supplier of technologies for the combustion engine, hybrid and electric vehicle markets, has introduced its newest High Voltage Hairpin (HVH) electric motor. The HVH 320 is designed for a variety of hybrid and electric applications for commercial vehicle manufacturers, including a large European OEM, the company said.

Production of the HVH 320, which is equipped with 800 V capabilities and available in four variants, is expected to kick off in 2024. Its multi-faceted platform is intended to support vehicle manufacturers’ goal of a common electric drivetrain and deliver approximately 97% peak efficiency and over 400 kW (536 hp) outputs.

“Adding the HVH 320 to our electric motor family bolsters our offerings and is an excellent example of BorgWarner’s commitment to delivering state-of-the-art clean propulsion technologies that match market needs,” said Dr. Stefan Demmerle, president and general manager, BorgWarner PowerDrive Systems. “Using our 800 V rated machine, customers can significantly reduce charging time and achieve a higher power density, enabling an even brighter future for electric trucks.”

BorgWarner said it leveraged its decade-plus of motor production to design four variants of its modular and flexible HVH 320 motor platform to meet the customer’s requirements. The motor is engineered to offer clean and quiet operation, while reaching a torque output of up to 1270 Nm (936 lb. ft.). The technology supports the vehicle’s shifting sequence and charges the battery by generating power while braking or driving downhill, the company said.

The HVH 320 motor is the newest addition to BorgWarner’s portfolio of HVH series motors, which are offered to both light-duty passenger cars and heavy-duty commercial vehicles. The motors incorporate patented stator winding technology, are designed for easy integration and are available as fully housed motors or as rotor/stator assemblies. Additionally, the motors can be used in a variety of architectural positions throughout a vehicle, the company said.

BorgWarner said it also offers inverters that can achieve the same, next-generation 800 V level.
