At the Institute of Electrical Machines, lifetime models of winding insulation systems of electrical machines are studied. In order to fulfill the application’s specific requirements, the combined aging processes are investigated, which can be considered in the design process of electrical machines. Electrical insulating materials change their specific material properties during their lifetime.
These aging processes are influenced by different aging mechanisms. Within these lifetime investigations, comprehensive lifetime models are developed, which allow the calculation of the expected lifetime with a probability for different loads. Therefore, modern measuring devices, a climate chamber, heating ovens and a vibrating table are available at the institute’s material laboratory.
