Who we are: 

The Rotating Machines Department is involved in research of electromagnetic and mechanical phenomena in electrical rotating machines using modern numerical calculation methods (FEM and CFD methods). Further, development of expert system for monitoring, control and fault detection of rotating machines (hydro generators, turbo generators, wind generators, induction motors). The main goal is help (users) owners of machines to achieve (better) asset management.

Expertise areas:  Parts manufacturing ,  Robots ,  Assembly systems ,  Flexible manufacturing systems ,  Real time systems ,  Monitoring and Control Networks ,  Modelling and model-based engineering
