Alternatives to Rare Earth Materials for Magnets

Understand the trade-offs between magnet-free motors and traditional permanent magnet (PM) machines, including performance and efficiency differences during technology evaluation, and examine how Tier-1 manufacturers are designing higher-efficiency e-motors while reducing rare-earth content.

"EESM is a solid option when magnet costs or tariffs account for a significant portion of the total cost of ownership. It's also the design that many European OEMs are adopting as they move rapidly towards rare-earth-free motors in the coming years."

This topic will be explored in-depth at EV/HEV Powertrain 2026.
