Electric and Thermal Stresses in Electric Machine Insulation (A04)

• Subject Area: Electronic Semiconductors, Components and Circuits, Integrated Systems, Sensor Technology, Theoretical Electrical Engineering
• Term: since 2022
• Project identifier: Deutsche Forschungsgemeinschaft (DFG) - Project number 492661287

Insulation systems in electric machines limit the permissible operating range and significantly determine the service life. Therefore, a complete knowledge of the electrothermal insulation system problem is essential for the mission of the CRC of developing holistic simulation design routines. This project models machine insulation systems as a coupled electric and thermal problem including realistic variabilities of the insulation material parameters and geometry. Transient or cycling operating stresses are simulated to predict insulation failures and to assess novel cooling strategies.
