Rotor Combined Design for High-Speed PM Machines

Article Preview

Abstract:

It is quite different to design a high-speed and high frequency machine than designing a common machine. Strength and dynamic characteristic analysis of rotor are key techniques for high-speed permanent magnet (PM) machine. Rotor combined design should be investigated based on mechanical with electromagnetic and dynamic properties analysis. The finite element method is used to analyze stress and electromagnetism field and dynamic characteristic. The multi-physics field iteration design is carried out by optimization analysis of the finite element software. A high-speed PM machine with rated speed of 60000 rpm, 75kW is presented with this method. The experimental measurements validate the correctness of this method.
