Abstract :
In this paper, we examined a modeling method for a vibration analysis in order to estimate the electromagnetic vibration of a stator case due to the resonance phenomenon between the natural frequency and the electromagnetic force. The resonance phenomenon can be verified on the analysis result as well as on the measurement result by setting the measured mechanical characteristics. We found it was important to accurately model the coil mass in order to estimate the electromagnetic vibration of the case, while the rigidity of the coil had little effect on the results.
