The Internet’s Verdict: 70% Hyped, 30% Skeptical

Expert Insights

Some experts praise the effort to reduce reliance on rare earths, but others raise concerns about the design’s limitations.

Unfortunately, their Web page does not say a single word about the important problems of their motors.

This lack of transparency fuels skepticism about the motor’s performance and maintenance requirements.

Another expert notes that

motors with no permanent magnets were the first practical ones, and at this point wound-rotor motors are over a century old.

This historical context suggests that the innovation may not be as groundbreaking as claimed.

Technical Comparison

BMW’s rare-earths-free motors offer almost twice the power and are on a 800v architecture, making them a more advanced option.
