摘要：
The application of pulse width modulation (PWM) in induction motor speed control is very popular nowadays. These pulses are responsible for high overvoltages at motor input terminals and for an uneven voltage distribution along the windings. New turn to turn electrical stresses provide the need of models capable of voltage prediction through stator coils. In this paper, a new methodology for a frequency domain voltage distribution prediction is presented. Model feasibility is proved using experimental data and different test cells.
