Abstract

In referring to ‘high performance motors’, we are referring to some aspect of electric motors that exceed normal industrial purpose motors: high speed, high torque, high power to weight ratio. In this discussion, I will be focusing on high speed motors for applications such as centrifugal compressors and high power to weight ratio, large machines as would be suitable for aircraft propulsion. Along the way I have a few ‘war stories’ of mistakes in design, made by myself as well as other motor designers. I will discuss some of the elements of motor design and how they can lead to high performance. Halbach arrays have been discussed and I will describe my misgivings about them, and will discuss as well winding schemes and, briefly, cooling. I will also describe, as I understand them, a pair of experimental machines under construction in the US, demonstrating technology suitable for aircraft propulsion motors.
