Two great minds in permanent-magnet-free motor design are fusing their know-how to create an even more capable inductive electric motor. Mahle and Valeo have teamed up to introduce what they call the ...

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 ...

The electric motors that power today’s EVs rely on permanent magnets made using rare-earth metals such as neodymium. Rare earths are the 15 elements whose atomic numbers run from 57 to 71, plus ...

The joint venture Astemo, a collaboration between Hitachi and Honda, has developed a new motor for battery-electric vehicles ...

MUNICH, Germany—ZF unveiled an electric motor that does not require magnets or rare earth materials, reducing reliance on mining in countries such as China and cutting manufacturing's carbon footprint ...

Closed-loop motor control generally requires sensors that accurately determine the position of the motor rotor to effectively implement communication of the excitation for the windings (an exception ...

Linear motors are becoming increasingly practical for general motion. Many are used for long strokes of a few feet or more. One new design, however, where the magnets move relative to a stationary ...

Renault said over 300 patents had been lodged for the design of the Megane E-Tech Electric. The automaker said it saw the electric motor play a strategic role in the EV value chain and decided to ...

Disc motors are permanent-magnet stepping motors that exhibit performance comparable to that of hybrid motors. Rotors in disc motors are thin (typically less than 1-mm) discs, unlike the cylindrical ...

A number of readers questioned the veracity of the technology presented in this article. To address their concerns, we did a follow-up, which can be found here. Permanent magnets are an integral part ...
