  ABSTRACT: The over-voltage phenomenon is usually described using the traveling wave and reflection phenomena in variable speed drive system. A voltage pulse, initiated at the inverter, being reflected at the motor terminals due to a mismatch between the surge impedance of the motor and the cable. In this paper, resistance, inductance and capacitance of the cable and the motor windings are obtained experimentally by modal measurements and suitable models are developed to match the experimental results by considering resonance in the motor winding. This paper emphasize on Induction motor model using the theory of natural modes of propagation. The developed model validity is investigated for inverter surge application.
