Design of a Stator for a High-Speed Turbo-Generator With Fixed Permanent Magnet Rotor Radius and Volt–Ampere Constraints

This paper investigates high-speed surface PM machine design for portable turbo-generator applications. The rotor radius is fixed to achieve certain optimal characteristics of the magnet retention mechanism. The objective of this paper is to design and select the stator. The stator designs are populated by different slot/pole combinations, winding arrangements, and over a range of possible stack l...
