The Integral e-Drive division of Integral Powertrain has collaborated with McLaren Applied Technologies and Hewland Engineering to design a new electric axle system. The CTU-400 e-axle features integrated inverter technology from McLaren, two 200 kW permanent magnet motors from Integral e-Drive, and two reduction gear sets for torque vectoring from Hewland.
The self-contained CTU-400 is intended to be sited adjacent to a high-voltage battery. It’s designed to be compact and light, and to be simple for manufacturers to integrate into vehicles. It requires only a single high-voltage DC connection from the battery and a single communications connection to the rest of the vehicle. Overall power density is 4.4 kW/kg. Bespoke variants can be provided to suit customer performance and package requirements.
“Integral Powertrain have always pushed the boundaries of e-drive technology, working with clients around the world to find the best solution to meet their requirements,” said McLaren Automotive Director Tim Strafford. “This collaboration, utilizing the expertise of all three companies, has produced an impressive technical solution that is cutting-edge in terms of technology, can be made competitively in small and high volume, and is scalable in design. I think you will struggle to find anything as power-dense on the market that is not in a motorsport application.”
