Abstract :
A vibration prediction model for the switched reluctance motor is constructed in this paper. Shaker and force hammer tests for vibration measurement are used for measuring crucial parameters like modal frequency and damping ratio for the transfer function. A detailed lookup table of normal force versus phase current and rotor angle is constructed based on finite-element calculations. The model is then verified by experiments, with acceptable accuracy.
