Abstract :
A novel method for the aging of magnetic wire in the conditions that resemble the stresses to insulation caused by power inverters is described. The test system for the purposes of the described aging program is discussed. A model of aging of magnet wire is developed and confirmed with experimental results. It has been found that voltage, temperature and frequency in that order of are the most important factors of influence. The correlation between the model and tested life in the corona conditions produced is excellent
