Method for radial vibration modelling in switched reluctance motor

The wide application of switched reluctance motor has been limited due to its high acoustic noise, which is mainly caused by radial vibration. In this study, a new radial vibration model is proposed consisting of vibration acceleration impulse model and natural oscillation model. The vibration acceleration impulse model is developed based on the measured sample data using least-square support vector machine method. Natural oscillation model is also proposed based on the superposition of each frequency, which is obtained by finite element method. The vibration model is built up in MATLAB/Simulink and various experiments have been conducted to verify the accuracy of the proposed model.
