At Tesla’s 2023 Investor Day on March 1, the company revealed that its next-generation permanent magnet synchronous motor (PMSM) traction motors would not use rare earth permanent magnets. “As the world transitions to clean energy, demand for rare earths is really increasing dramatically and not only is it going to be a little hard to meet that demand but mining that rare earth, it has environmental and health risks,” Tesla powertrain engineering VP Colin Campbell said.
