Work Groups


The main research activities of the Institute of Electrical Machines, IEM for short, are design, calculation, measurement technologies, drive control and operation of electrical machines. The IEM with its mechanical workshop is able to build functioning prototypes for measurement purpose running on more than 35 test benches in the IEM. Measurement technologies for several research issues, as well as measurement electronics, are developed in-house. All relevant machine types are considered in the institute‘s research. To cover the relevant research topics, four research groups are organized at the IEM.


Analysis and Modelling

The workgroup deals with the characterization and modeling of the magnetic core and insulation system and their effect on the operational characteristics of electrical machines. Therefore, specialized experimental characterization methods are utilized as well as modeling and model coupling for ferromagnetic materials and isolation materials. Current topics such as the production influences, life time analysis, partial discharge or anisotropic material behavior are research objectives. Depending on the problem, specific solutions and problem-oriented approaches are developed.
