摘要：

This article investigates the stator modal modes in stator-permanent magnet (PM) machines. Flux-reversal PM (FRPM) machine and flux-switching PM (FSPM) machine are taken as examples to investigate the different influences of PMs on the stator modal modes. Lagrange's equations and Rayleigh-Ritz method are combined in the proposed analytical modal analysis method. Based on the different influences brought by the PMs, the stators in stator-PM machines are analyzed correspondingly. Meanwhile, composite material theory is also introduced to teeth remodeling and the subsequent modification of isotropic material properties. The modal experiments of stators in different stator-PM machines are carried out and validate the feasibility of the proposed analytical modal analysis method of stator modal modes. The analytical modal analysis of the whole prototype is also carried out and compared to the experimental results, which proves the credibility of the proposed model.
