Goldfish: A versatile concept of variable flux memory machines with mutating characteristics

Important results from the project

The goal of the project was to investigate the potential of Variable Flux Memory Machine (VFMM) technology. Initially to reach this conclusion, a fundamental understanding of the technology itself was gained through analysis of the available literature. Subsequently, a strategic approach targeting the development of hysteresis models, in-depth understanding of the physics behind the re-magnetization procedure and its impact on the machine performance was followed. The conclusions were supported via detailed simulations of real-cases over the full operational speed range.

Expected long term effects

From a strategic perspective, the successful conclusion of the project enables new approaches and research directions towards novel concepts of electrical machines offering enhanced efficiency, as well as the introduction of new methodologies and tools for the analysis of the respective machine topologies. In addition to the possibility of novel technology releases, the academic experience gained by the involved researcher is expected to have a detrimental impact on his personal development improving his future career possibilities.

Approach and implementation

During the full duration of the project Dr. Iakovos Manolas, the key researcher and contributor of the project, was located at NTUA, carrying out all the research work there. Professor Kladas (NTUA) followed closely the progress of the project offering mentorship and researchers in ABB contributed actively with a proven industrial track record on machine design and converter control. The project plan and budget have been executed accurately in terms of time and content. As deliverables of the project, two scientific articles have been presented in international IEEE conferences.
