China controls about 90% of the entire global supply of rare earth magnets, including their mining and refining. That means ...

If you think shorting a transformer’s winding means big sparks and fried wires: think again. In this educational video, titled The Magnetic Bypass, [Sam Ben-Yaakov] flips this assumption. By … ...

BMW’s latest axial flux motor patent locks in magnets with a unique metal package and axial stop, aiming for better performance, safety, and long-term durability.

The lack of a yoke and locating the magnets away from the central axis result in higher power-to-weight ratios than equivalent radial flux motors. The EVOA E1 and Acel outboards use axial flux motors.
