Electric motors are weaning off rare earths

Once prized for performance, rare-earth magnets are becoming a strategic risk—forcing electric motor designers to rethink everything from torque to cooling.

The electric motor industry is hitting a supply-chain wake-up call. Around 95 percent of new EV motors still rely on rare-earth magnets, largely sourced from China. Export controls, price swings, and environmental concerns are turning that reliance into a growing risk.

Automakers and suppliers are now pushing rare-earth-free alternatives, including induction, wound-field, and switched-reluctance motors. BMW already uses magnet-free designs in production EVs, with Renault, Valeo, GM, and others following.

The shift brings trade-offs in size, heat, and torque density, but improved cooling and smarter designs are closing the gap. What’s emerging is a long-term pivot toward cost stability, supply security, and more resilient motor architectures.
