Exploring Why This 17-Year Old’s Electric Motor Is Important. Get Surfshark VPN at https://surfshark.deals/undecided – Enter promo code UNDECIDED for 83% off and 3 extra months for FREE! Permanent magnets are a critical resource for renewables, because the generators in some wind turbines and motors in electric vehicles rely on them to run. A Floridian high school student has just shown us how to make a better electric motor without rare earth magnets. Another company is using cloud computing to try to improve electric motor performance — also without rare earths. There’s some exciting advances being made when it comes to electric motors, but how much of a difference can they make?

I’ve trimmed a couple of short sections from the video that were creating confusion. I didn’t mean to imply that AC motors use magnets, but the wording during some moments made it sound like I was. Magnetless motors are not a new thing, but optimizing their design for high efficiency, high torque, without rare earths opens the door for more use cases.
