Abstract

Models incorporating different levels of sophistication are presented for predicting the surge distribution in motor stator windings. Results predicted by these models have been validated against experimental results. Simple models, which provide insight into the relevant mechanisms, are presented for estimating the interturn voltage and the line-end coil voltage, and they are used to derive guidelines for evaluating alternate winding designs. A detailed model which has been solved using the Electromagnetic Transients Program (EMTP) software package is presented for more accurate prediction of interturn voltages. The influence of coil design parameters on the surge distribution is discussed
