| Abstract: | An analytical method of calculating the radial airgap flux density and electromagnetic force wave based on waveform reconstruction method was proposed, which simplified the calculation process of electromagnetic vibration and noise (EVAN) of permanent magnet motor and solved the complex problem of calculating the radial electromagnetic force wave of permanent magnet motor. Firstly, the theoretical basis of waveform reconstruction method to calculate EVAN of permanent magnet motor was introduced. Then, taking a permanent magnet motor as an example, the steps of calculating the EVAN of permanent magnet motor using waveform reconstruction method were introduced in detail. Finally, the multiphysical field finite element simulation of EVAN of the permanent magnet motor was carried out, and the calculation results of waveform reconstruction method were compared with those of finite element simulation results. Within the allowable range of error, the calculation results of the two methods were consistent, which verified the accuracy of waveform reconstruction method in calculating the EVAN of permanent magnet motor. |
