The electric vehicle penetration at global level is expected to surge in the coming years. While permanent magnet motors are convenient in terms of power density and efficiency, the use of rare earths is problematic for multiple reasons.
The ReFreeDrive project (www.refreedrive.eu), funded by the European Commission, has pushed the boundary of two motor technologies which do not use any critical raw material at all: induction with copper rotor and synchronous reluctance. The specific torque is increased by 30%, motor losses reduced by 50% and costs by 15%, while delivering a solution feasible for mass production.
In this webinar Motor Design MDL, IFPEN Energies Nouvelles and University of Aquila will explain in detail the design of different motors which can meet the specifications of Jaguar Land Rover vehicles. Multiple innovations will be presented: optimised electrical steels, special copper alloys, new manufacturing methods, hairpin winding and innovative cooling systems, among others.
