“…High power density usually increases the rate of heat generation within the rotating electric machine. Rotating electric machines depend on electrical insulation systems to maintain the proper 1 Mechanical Engineer, Thermal Energy Systems Lab, ES-105, AIAA Member 2 Electrical Engineer, Electrical Propulsion Systems Lab, K1-4C39 3 Mgr-Turbine Heat Transfer Technologies Laboratory, K1-3B17A, AIAA Member 4 Mechanical Engineer, Seals Lab, K1-3B8A, AIAA Member 5 Electrical Engineer, Electrical Machines Lab, EP-107 6 Mechanical Engineer, Electronics Cooling Lab, ES-208 7 Mechanical Engineer, Electronics Cooling Lab, ES-207 8 Mechanical Engineer, Electrical Machines Lab, EP-124 potential and currents that allow appropriate electromagnetic field interaction. The insulation systems are rated by temperature, and excessive temperature reduces their ability to avoid current leakage and dielectric breakdown.…”
