Vibration Prediction in Switched Reluctance Motors With Transfer Function Identification From Shaker and Force Hammer Tests

Abstract—A vibration prediction model for the switched reluc-tance motor is constructed in this paper. Shaker and force hammer tests for vibration measurement are used for measuring crucial pa-rameters like modal frequency and damping ratio for the transfer function. A detailed lookup table of normal force versus phase cur-rent and rotor angle is constructed based on finite-element calcu-lations. The model is then verified by experiments, with acceptable accuracy.
