Alternatives to permanent magnet motors in EV traction applications

Charged EVs

As the name implies, the axial-flux PMSM orients its field magnets parallel to the output shaft on a disc that is sandwiched between the stator phase windings (and the “back iron” to complete the magnetic path, if necessary). materials like woven carbon fiber composite.

While they store a high amount of energy compared to the other designs, their power output is comparatively low. Under a venture with the motto “From Road to Grid”, Audi is therefore currently working on a concept to convert old batteries into stationary energy stores. Pouch cells and prismatic cells are more versatile.

It’s –27 °C, dipping below –40 °C with wind chill—well below the operating temperature of most of the commercial equipment we brought for this expedition. These great masses store enough water to raise global sea level by 65 meters should they melt entirely. Our phones, laptops, and cameras are rapidly failing.
