Abstract :
The aim of this study is to investigate the lifetime characteristics of magnet wire insulation. Accelerated life tests are performed on twisted pairs of magnet wires at different high temperatures, frequencies, and pulse voltages. Weibull distribution is used to analyze the collected data. The electrical-thermal-frequency life model is used to estimate the insulation life of magnet wire under any desired stress. The parameters of the electrical-thermal-frequency life model are estimated using the least square technique.
