Power Loss and Thermal Analysis of a MW High-Speed Permanent Magnet Synchronous Machine
IEEE transactions on energy conversion
High speed permanent magnet synchronous machines (PMSMs) have attracted much attention due to their high power density, high efficiency, and compact size for directdrive applications. However, the consequent power loss density is high, and hence heat dissipation is a major technical challenge. This is particularly the case for high-speed operation. In this paper, a MW level high speed PMSM is designed and its electromagnetic and mechanical power losses comprehensively investigated using finitedoi:10.1109/tec.2017.2710159 fatcat:kb6hq4rtqzfgvjvypfdeenqnde
