Magna is planning to develop a more advanced electric motor for electric vehicles (EV) which will be more powerful and affordable, the company announced in a press release on 30 October. Magna will partner with Illinois Institute of Technology, the University of Wisconsin-Madison and the United States Department of Energy (DOE) for the project. THe DOE has also awarded a grant to Magna for the development. The electric motor technologies will be presented to DOE for evaluation in 2021.
“Magna’s mission is to make the impossible possible by solving some of the auto industry’s most complex problems. Reducing dependency on rare-earth magnets solves two key issues for accelerating access to electrification—supply chain sourcing and cost,” said Swamy Kotagiri, chief technology officer, Magna.
Significance: Magna said that it will use its expertise in powertrain, electronics and full-vehicles to develop an automotive-grade, high-performance electric motor that aims to achieve increased power density and reduce cost compared to current e-motors. The goal of the project is to develop a motor that is half the cost and eight times the power density, while delivering 125 kW of peak power. To reduce the cost, Magna will eliminate the use of rare-earth permanent magnets. The project scope includes development and use of innovative materials, cooling technologies, winding technologies, simulation models, as well as control and optimization techniques. As part of the project, Magna will integrate the exclusive electric motor technologies with a transmission and inverter as part of an overall e-drive system.
