The HIECS Center of Excellence

Technology for a Cleaner Future

The Center of Excellence in High-Speed Electromechanical Energy Conversion Systems (HIECS) was launched via the Academy of Finland's Center of Excellence Programme 2022-2029. HIECS will establish the necessary theories and tools for renewing the understanding of high-speed electromechanical drivetrains: high-speed electrical machines and the associated machinery.

Real-World application areas

The electrification of aviation and emerging hydrogen economy are opening new application areas for electromechanical energy conversion: propulsion motors as well as compressors and turbine generators. These applications also call for unprecedented power densities and efficiencies of the machines.

The most promising way of reaching these targets is increasing their operating speeds and frequencies, improving their material-efficiency and reducing their size and weight. Thus, high-speed, high-frequency technologies offer a sustainable solution for the future energy conversion needs.
