Abstract	For the high-frequency permanent magnet electrical machine, a reasonable mechanical aspect design is crucial to meet its stability and reliability. This study focuses on the accurate modelling and analysis of the natural frequencies and modes of the rotor assembly for a designed and manufactured 100 kW 32,000 r/min motor. The influence of contact stiffness and friction on bending frequencies is analysed in detail. To obtain the accurate results of first two bending frequencies, on the basis of the finite-element method, the optimisation method is carried out to acquire appropriate variables of the contact stiffness and friction. The optimised results show that the method proposed in this study can realise the accurate analysis of the rotor mode, which are verified by free–free modal testing of the rotor.
