In order to meet this need, a high specific power electric machine with an unconventional topology is being developed. The topology creates mechanical challenges including expansion due to high speed, and thin radial builds that affect rotordynamics. Similarly, the design creates thermal challenges, of which extracting heat from a small geometry, and the difficulty of estimating windage losses because of the high speed and large diameter, are two.
