JEE_V9_N3_RP4 Transient Model and Detection of Stator Inter-Turn Fault in Inverter Driven Induction Motor Drives by Time Domain Technique Khadim Moin Siddiqui Kuldeep Sahay V.K. Giri Journal on Electrical Engineering 2230 – 7176 9 3 20 31 Squirrel Cage Induction Motor, Stator Inter-turn Winding Fault, Time Domain Analysis, Motor Current Signature Analysis, Modelling and Simulation, Pulse Width Modulated Inverter These days, the induction motor driven by inverter, drives are being popular and used in the industries for variable speed applications with very competitive pricing. In this paper, a new dynamic pulse width modulated inverter fed squirrel cage induction motor simulation model is used for the stator inter-turn winding fault detection purpose. Through the proposed model, the transient behavior of the induction motor has been analyzed for healthy as well as for stator interturn faulty conditions by time domain approach. Therefore, early, stator inter-turn fault diagnosis is possible and may avoid the motor to reach in the catastrophic conditions. Therefore, may save large revenues for industries.
