Permanent magnet motors use magnets—rather than windings—to create the magnetic field necessary for motor operation. This design eliminates the need for external excitation and significantly reduces ...

It also weighs about as much as a bike. Combine the power and the weight, and you get a new unofficial power density record.

Mercedes’ YASA-built axial-flux motor weighs less than a toddler yet produces over 1,000 horsepower, setting a new benchmark ...

Several companies around the globe have been hard at work innovating and refining magnet-free electric motors to make them a more viable option for the fast-growing EV industry. ZF Friedrichshafen has ...

Last month, at a livestreamed Tesla investor event that went short on new cars and long on grandiose narratives, a minor detail in Elon Musk’s “Master Plan Part 3” made big news in an obscure corner ...

China controls about 90% of the entire global supply of rare earth magnets, including their mining and refining. That means that most of the neodymium, dysprosium, and terbium that end up in EV motors ...

When you think of electric motors, you usually think of magnets. But magnets are heavy, and good magnets can pose problems when you need lots of them. A technology called SESM (separately excited ...

A new magnetic digital encoder featuring 14-bit resolution, differential outputs, and a speed range of up to 200-k e-RPM offers accurate and cost-effective position sensing for various robotic and ...
