BMW has a novel way to hold the magnets in place in an axial flux motor, with an eye toward efficiency and long-term durability. Being a central part of the motor core, rotor design is critical to ...

To visualize a radial flux motor, think of two iron cylinders. One is fitted with magnets set around its outside and an axle running through its center (the rotor). Surrounding this cylinder is a ...

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 ...

A new permanent magnet motor structure promises to greatly improve the efficiency of appliance and servo motors without increasing overall manufacturing costs. Utilizing a unique axial motor design ...

ZF has announced the development of a new electric motor that eliminates the need for magnets found in traditional electric drive motors. The company’s new I2SM with inductive exciter technology ...

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 ...

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 ...

Mercedes-Benz provided a flight from DC to San Diego and a return from Los Angeles, plus four nights’ hotels so we could meet the Vision One-Eleven as well as drive a new Mercedes-AMG plug-in hybrid ...

The Yasa electric motor challenges conventional expectations of size and power in automotive engineering. Weighing just 12.7 kilograms (28 pounds), this compact axial flux motor delivers an impressive ...
