Method to Predict the Non-Uniform Potential Distribution in Random Electrical Machine Windings under Pulse Voltage Stress

This article describes a practical method for predicting the distribution of electric potential inside an electrical machine’s winding based on design data. It broadens understanding impedance in terms inter-winding behavior and allows to properly insulation system during development phase. The predictions are made frequency-dependent equivalent circuit machine which is validated by measurements time domain frequency domain. Element parameters derived from two-dimensional field simulations. results demonstrate non-uniform that difference between individual turns stator core exceeds expected values. findings also show link oscillations winding. Additionally, provides overview chronological progression turn-based models shows how asynchronous multiprocessing used accelerate solution process circuit.
