The International Electric Machines and Drives Conference (IEMDC) is a premier biennial forum covering every aspect of electric machines, power‑electronic drives, and their applications. Since its launch in 1997, and under the sponsorship of the Institute of Electrical and Electronics Engineers (IEEE), IEMDC has connected researchers, industry engineers, and academics from around the globe.
The 2025 edition will take place 18–21 May at The Westin Houston – Memorial City (Houston, USA) and is expected to draw more than 600 participants from academia, research institutes, and a wide range of industrial sectors, including maritime.
The MARPOWER project will be represented by its coordinating entity, LUT University, with two highlighted poster presentations by junior researcher and co-author Kristof Szombati:
- “Axial Active Magnetic Bearing with Laminated Stators and Slit Rotor Disc Used in On-Board Machinery” (poster #7232) will be introduced on Monday, May 19 from 5:30 to 7:00 PM in the Azalea Ballroom, as part of the “Rotating Electric Machines 4” track during Poster Session 1.
This study addresses the challenges of using active magnetic bearings (AMBs) in high-speed rotating machinery, particularly in demanding environments such as onboard ships. It highlights the limitations of traditional AMB designs with solid iron components, which suffer from high eddy current losses and temperature rises during dynamic events. To overcome these issues, the study proposes new configurations using laminated or layered stator cores and a slit rotor disc to reduce losses, improve thermal management, and enhance dynamic performance.
- “Multidisciplinary Design Approach for On-Board High-Speed Energy Conversion Machinery” (poster number #7303) will be presented on Tuesday, May 20, from 3:30 to 5:00 PM in the Azalea Ballroom, as part of “Design Optimization, Modeling & Simulation 6” track during Poster Session 3.
This research presents a rapid, multidisciplinary design approach for high-speed electrical machines used on ships, aiming to support the energy transition in maritime applications. It integrates critical factors such as process parameters, rotordynamics, magnetic bearings, electromagnetic design, structural considerations, and ship motion effects. Unlike traditional, time-consuming sequential methods, this approach emphasizes faster analytical design while addressing key gaps, particularly the lack of integration between structural, dynamic, and application-specific factors. The study uses a high-pressure shaft system from a marine gas turbine to illustrate design trade-offs and interdependencies across various domains.
In addition to these MARPOWER contributions, the LUT team will be active throughout the IEMDC event, participating in several other oral and poster presentations. The full list of sessions and talks can be found in the event’s official program.
We look forward to engaging with the electric‑machine and drive community in Houston. See you at IEMDC 2025!
