FEV has introduced a collaboration with the Instructing and Analysis Space Mechatronics in Cellular Propulsion at RWTH Aachen College to develop a modular electrical drive unit platform aimed toward lowering reliance on rare-earth parts in EV motors.
The brand new platform minimizes using crucial uncooked supplies akin to rare-earth magnets, with the aim of eliminating them fully. The developed idea encompasses a modular structure comprising a shared stator, housing, cooling system, and converter, with interchangeable rotors.
FEV says that technical research exhibit rare-earth-free alternate options can obtain total efficiencies as much as 94 %, whereas reducing price volatility and lowering carbon dioxide equivalents over the motor’s lifecycle.
To judge efficiency and price, engineers from FEV and RWTH Aachen College investigated electrically excited synchronous machines, ferrite-based electrical machines and asynchronous machines as alternate options to conventional completely excited synchronous motors with rare-earth magnets.
The platform targets mid-range (C phase) and luxurious (D phase) EVs, supporting peak outputs of 160 kW and 250 kW, and may be tailored for decrease car segments via its modular design.
FEV says the platform’s oil cooling system with direct stator and rotor cooling allows a considerable improve in steady energy output. The ratio of steady to peak energy surpasses typical techniques by as much as 75 %.
“Our platform strategy permits car producers to react sooner and extra flexibly to market shifts, uncooked materials shortages, and price fluctuations, “mentioned Patrick Hupperich, President and CEO of FEV Group. “That is achieved with out compromising effectivity or efficiency.” The modular platform permits unique gear producers to accommodate totally different drive ideas just by altering the rotor, streamlining growth and bettering provide chain diversification.
