Mechanical Design Considerations of an “Ironless,” High-Specific-Power Electric Machine

Abstract

This paper describes the mechanical design considerations for a 1 MW, 14 000 rpm motor which achieves a specific power of at least 13 kW/kg. This is enabled through an “ironless,” inside out, Halbach array permanent magnet, high frequency, and airgap or slotless configuration. The “ironless” design creates mechanical challenges because thin radial builds… (More)
