This paper analyzes the main factors which can lead AC-motor wire insulation to premature failure when supplied by power electronic converters. In particular, experimental results show that the presence of partial discharge activity is able to accelerate insulation aging particularly of organic insulated motors with respect to sinusoidal conditions. Peak-to-peak voltage, together with pulse repetition frequency, are observed to be the main factors accelerating wire insulation aging.
