Abstract :
In this paper, the effect of PWM voltage waveform on the stator windings of random wound cage induction motors is studied. A method of estimating the distributed circuit parameters of the motor using finite element analysis is described. From these parameters, an equivalent circuit is formed with distributed capacitances and inductances. This circuit is then used for simulation using SABER in order to predict the voltage distribution among the turns and coils during a PWM wavefront. The effect of switching time of the inverter on the voltage distribution is also simulated. In order to validate the method adopted, the simulated results are compared with experimental results
