Abstract :
The purpose of this paper is to analyze the orbital response of rotor due to unbalanced electromagnetic force for switched reluctance motor (SRM). In order to reduce vibration of SRM, it is necessary to predict the mechanical dynamic behavior of the rotor-bearing system. So the orbit of the rotor according to rotation speed is analyzed by using the finite element method (FEM), and unbalanced electromagnetic force induced by dynamic eccentricity is calculated by the Maxwell stress tensor. From the results, the stability behavior of the rotor caused by unbalanced electromagnetic force is evaluated
