Germany-Based Vitesco Technologies Debuts EV Drive Unit Built Without Rare Earth Minerals

29 May 2023 | Abstracted from Clean Technica

"...the fourth generation of the fully integrated electric axle drive platform...now includes a new rotor without permanent magnets at its core, which constitutes an externally excited synchronous machine (EESM) that operates without the need for rare earths...this innovation lowers the rotor's cost and eliminates the carbon footprint associated with the mining and processing of these ores...the externally excited machine conserves one watt-hour of electricity per kilometer due to the absence of drag from a permanent magnet field in the rotor."
