Abstract :
Longer life time is required to commercial hybrid vehicle than that of passenger hybrid electric vehicle, like conventional commercial and private vehicle. On the respect of electric motor of hybrid powertrain, the lifetime of electric motor mostly depends on the two factors; electric insulation degradation and fatigue of bearings. In electric motor design, especially used in commercial hybrid powertrain, the reliability and lifetime estimation is very crucial in order to meet the lifetime requirement.
