Before this neodymium-iron-boron magnet came along in 1984, electric motors, generators, audio speakers, hard-disk drives, and the like had to make do with pricey samarium-cobalt magnets.

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 ...

The most used is Neodymium, which is used in powerful magnets for speakers, hard drives, and electric motors. Dysprosium, Terbium and Praesodymium are commonly used as additives in Neodymium magnets.

Bro, by magnets they clearly mean permanent ones, the ones made with rare earths, the expensive kind. Motors that use it constitute a Brushless Permanent Magnet Motor, or BPM.

"With this magnet-free e-motor without rare earth materials, we have another innovation with which we are consistently improving our electric drive portfolio to create even more sustainable ...

The video explained that most electric car motors require magnets made from rare-earth elements, which can be costly, both financially and environmentally, to extract.

The future of electric vehicles has become more environmentally friendly, according to ZF, which has produced an electric motor without rare earth metals that doesn’t compromise on performance. During ...

ZF has developed a magnet-free electric motor disparate to Separately excited synchronous motors. The motor is compact with maximum power and torque density as ZF’s I 2 SM (In-Rotor Inductive ...
