In this paper, the influence of rotor-step skewing on the vibration and noise characteristics of a permanent magnet synchronous motor (PMSM) with consideration of rotor step skewing is investigated.Abstract:
Radial force F
r
is the main cause of electromagnetic vibration and noise in motors. In this study, the vibration and noise characteristics of a permanent magnet synchronous motor (PMSM) with consideration of rotor-step skewing are investigated. Firstly, the analytical model of F
r
considering rotor-step skewing is deduced based on the Maxwell stress tensor method. The influence of rotor-step skewing on F
r
of the PMSM is then analysed and summarised. Taking a 65 kW PMSM commonly used in electric vehicles as an example, combined with electromagnetic finite element analysis, F
r
is then evaluated. Secondly, an electromagnetic vibration and noise simulation analysis is conducted based on a multi-physical field joint simulation platform, from which the influence of rotor-step skewing on the vibration and noise is then summarised. Finally, a noise experiment is then carried out. The results obtained from the multi-physical analysis and the tests conducted are presented to validate the precision of the simulation models, and the accuracy of the analytical model of F

Permanent Magnet Synchronous Motor Magnet Designs with Skewing for Torque Ripple and Cogging Torque Reduction
TL;DR: In this article, the effect of slot/pole combinations and magnet shapes on the magnitude and harmonic content of torque waveforms in a permanent magnet synchronous motors with skewed rotor has been studied, and experimental results show that for certain magnet designs and configurations the skewing with steps does not necessarily reduce the ripple in the electromagnetic torque, but may cause it to increase.
