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 ...

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 ...

Tesla was first to patent a primitive axial-flux electric motor—Nikola Tesla, that is, way back in 1889. It would be 126 years before the concept found its way to a car, the 1,500-horsepower (1,103 ...

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 ...

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 ...

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 ...

Any enthusiast will be able to tell you the seat-of-the-pants characteristics of their favorite engine. The torque-peakiness of an Eighties turbo car, the endless rev-hungry climb of a naturally ...

The Blacksheep One turns exotic axial-flux EV tech and billet aluminum into rolling mechanical art. But is it really worth ...

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 ...
