Abstract :
The high-speed permanent magnet(HSPM) machines are extensively concerned in industries due to simple structure, high power densityand high frequency. This paper introduces a kind of hybrid rotor with Halbach configuration and graphite composite sleeve. The hybrid cooling technology of stator water cooling and rotor forced air cooling is adopted to prevent the PM from demagnetization at high temperature. A HSPM machine with 1.12 MW, 18000 rpm for direct driving of compressors is designed based on the multi-physics coupled analysis such as electromagnetic / temperature / stress / fluid fields. The experimental measurements validate the correctness of some methods.
