Alexandros Sergakis is a Ph.D. candidate at the School of Electrical and Computer Engineering, Technical University of Crete. His doctoral research focuses on fault diagnosis and prognosis in electromechanical systems for renewable power production, with particular emphasis on condition monitoring of direct-drive permanent-magnet synchronous generators used in offshore wind and marine energy applications. His work combines high-fidelity 3D finite element analysis, signal processing, and experimental validation to detect critical faults such as partial demagnetization and inter-turn short circuits in permanent-magnet machines. He holds a Diploma in Electrical and Computer Engineering from the Technical University of Crete, where his thesis examined fault diagnosis in direct-drive permanent-magnet generators for offshore wind turbines. Since 2024, he has been contributing as a researcher to the EU Horizon and UKRI-funded MEGA PTO WAVE project, focusing on diagnostics for low-speed, direct-drive coreless permanent-magnet generators in marine energy converters. His research output includes journal publications in IET Electric Power Applications and Energies, as well as conference papers presented at ICEM, IEEE SDEMPED, and IEEE EEEIC/I&CPS Europe. He has also gained international research experience as a visiting Ph.D. student at the University of Valladolid, where he worked on condition monitoring of permanent-magnet machines through experimental fault-diagnosis campaigns.
Through the IKY–Fulbright fellowship, Alexandros will conduct a six-month research residency at Purdue University’s Elmore Family School of Electrical and Computer Engineering from October 2026 to March 2027, under the supervision of Dr. Thomas C. Krause. His Fulbright project will focus on improved condition monitoring of permanent-magnet electric machines, integrating modeling, simulation, sensing, signal processing, and experimental validation. At Purdue, he will work on diagnostic methods for rotor permanent-magnet demagnetization and stator inter-turn short circuits, using the university’s ECE laboratories to validate his modeling and simulation work experimentally. This research visit will strengthen the experimental foundation of his Ph.D., support future high-impact publications, and contribute to the development of more reliable monitoring strategies for renewable energy and energy-machine applications.
