Abstract

This paper presents the multi-physics fields research of a high-speed permanent magnet machine (HSPMM) for turbine application. At first, the design considerations for the HSPMM are introduced and presented. Then, the machine electromagnetic performances are comprehensively studied with machine stator slot numbers. Moreover, the influences from the PM magnetization methods and segmentation number on PM eddy current loss reduction are further investigated. Thermal analysis is also performed for the HSPMM with the cooling water fluid volume flow rate considered. In addition, rotor strength is studied for the HSPMM with several design factors on machine rotor strength performances further studied and researched.
