Design Aspects of a High-Speed Electric Machine Series

This paper presents design aspects of and a new design approach to a high-speed electric machine series taking into account the multiphysical processes occurring in a highspeed permanent magnet machine. The proposed design approach ensures minimal design complexity, material, and production costs. Interconnected electromagnetic, thermal, and electrical calculations are performed. Three prototypes of highspeed permanent magnet machines are designed and built. The effectiveness of the proposed design approach is proved experimentally. The discrepancy between the experimental and calculated data is below 5%. The results can be useful to scientists and engineers who are engaged in the design and production of high-speed permanent magnet machines.
