Abstract To solve the problem of strength calculation of carbon-fiber retaining rotor for MW high-speed permanent magnet (HSPM) machine,the 3D fluid-thermal-solid coupling for a 1.12 MW, 18 000 r/min HSPM machine was calculated. Firstly, the finite volume method was used to calculate the temperature field and the fluid field of the machine, to achieve rotor temperature field distribution and its transmission. The simulation results were verified by experiments. Then, the thermal stress distribution of the rotor under the service condition was obtained based on the results of the rotor temperature field by exerting the corresponding constraints. The strength variation of the carbon fiber rotor under the multi-field coupling condition is summarized.

Key words： High-speed permanent magnet machine multi-field coupling three-dimensional temperature field fluid field stress field
