摘要：
The design of solid cylindrical ultra-high-speed permanent magnet (PM) machine is supposed to take multi-physics constraints into consideration, for its high rotor linear velocity and high loss density. Due to above problems, the analytical stress model of cylindrical PM rotor is developed, which could calculate the rotor stress and the minimum thickness of metallic retaining sleeve accounting for the influence of centrifugal force, thermal stress and interference fit. The analytical model of armature reaction considering eddy current reaction was proposed to analyze the rotor eddy current loss and its distribution. Based on the stress model, the limit speed of the rotor equipped with austenitic stainless-steel sleeve at certain temperature rise of hot state was analyzed. The rotor eddy current loss was given to the finite element software for rotor temperature calculation. To realize ultimate design, stress analysis and temperature rise calculation were combined to analyze the power limit of rotor and the control strategy at the temperature rise. A 40 kW, 60 000 r/min ultra-high-speed PM machine was designed with above models and analysis method, and the prototype was manufactured for supercritical CO2 power generation. Results of finite element simulation and experiments are given to verify the accuracy of the models and the effectiveness of the design. © 2023 Editorial Department of Electric Machines and Control.
