Magna wins DOE grant to develop cheaper EV motor with 8x more power density

The US DOE has awarded a grant to Canadian parts supplier Magna to develop e-motor technologies for next-generation propulsion systems that are both cheaper and more powerful than today’s technology.

The supplier has partnered with the Illinois Institute of Technology and University of Wisconsin-Madison for the initiative. The organizations aim to develop an e-motor that achieves eight times the power density of current e-motors at half the cost, all while delivering 125 kW of peak power. They hope to reduce cost by eliminating the use of rare earth permanent magnets, which Magna says make up a significant portion of the cost of current e-motors.

The project will integrate the motor technologies with a transmission and inverter as part of a comprehensive e-drive system. The project scope includes development and use of innovative materials, cooling technologies, winding technologies, simulation models, and control and optimization techniques.

The partners will present the motor technologies to the DOE for evaluation in 2021.

Magna CTO Swamy Kotagiri said, “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.”
