Abstract :
In the design of electric machines for a variety of applications such as hybrid electric vehicles, severe and regular duty applications, it is important to determine the reliability of the machine. The insulation system, in particular, is subject to multi-factor stresses including electrical, thermal and mechanical that impact the reliability of the machine. In this paper we will present a model for the analysis of multi-factor aging an insulation system developed to estimate the reliability of machine insulation systems in the design phase.
