Traction system for traction in commercial vehicles and other Off-Highway applications

The Traction systems consists of an electric motor paired with the traction inverter. They  were specifically designed for heavy-duty commercial electric vehicle applications and provide more than 95% system efficiency. These systems provide the highest continuous power and torque in their class. Designed to meet the most rigorous applications for durability and functional safety, these systems are also a scalable design to future-proof the most diverse commercial EV/HEV/PHEV platforms. This system is designed for pairing with various transmissions as well as integrated into eAxles for optimizing overall vehicle drive train efficiency, increased vehicle range, and total cost of ownership.
