Electric Motor for Hybrid City Bus Use

05 September 2017

A hybrid bus from Scania is using the BorgWarner High Voltage Hairpin (HVH) 410 electric motor. Positioned between the clutch and gearbox in a P2 layout, the 650-volt electric motor drives the vehicle at low speeds when enough energy is available. The motor also charges the battery by generating power while braking or driving downhill and supports the shifting sequence in the automatic mode of automated manual transmissions.

"As a key enabler for parallel hybrid drive concepts for commercial vehicles, BorgWarner's HVH410 electric motors help meet both market demands and emissions regulations," said Dr. Stefan Demmerle, president and general manager of BorgWarner PowerDrive Systems.

The motors are available as fully housed motors or as rotor/stator assemblies. They deliver a maximum torque of 2,000 newton meters and a power output of up to 300 kilowatts (402 horsepower) with peak efficiencies of over 95 percent.
