Higher power and torque density in advanced electric motors for land, air, and naval electric vehicles, along with increased efficiency are of key importance to improve vehicle performance. One way to realize these goals is by constructing the stator and rotor using high induction, high permeability, and low loss soft magnetic materials. Using such advanced soft magnetic materials allows a given EV design higher acceleration, improved range, higher payload capacity, and increased space savings. Recent advancements in the processing of thin laminated stator and rotor stacks have been paramount in enabling optimal motor performance.

Several examples of power dense and high efficiency motors using high performance soft magnetic alloys will be presented in detail. High induction, high permeability, and low loss soft magnetic stator and rotor materials to increase… Read More »Higher power and torque density in advanced electric motors for land, air, and naval electric vehicles, along with increased efficiency are of key importance to improve vehicle performance.
