《Calculation of Circumferential Modal Frequencies of Permanent Magnet Synchronous Motor》
As can be seen from Table 3，w ith the increase of the order of the circumferential modes，the relative errors betw een Hoppe theory and numerical method are more and more larger，but the relative errors betw een Donnel-M ushtaritheoryandnumerical method are more and more smaller.In order to analyze the reasons，by comparing the changed rate of respective frequencies to investigate the varied trend of frequencies，the results of changed rate of frequencies of stator core are show n in Table 4.
