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 soft and hard magnetic materials, insulation systems and the electrical machine’s structural dynamic and acoustic behavior. The prediction and reduction of parasitic effects in electrical drives, electromagnetic forces, acoustic emission, manufacturing tolerances, fault diagnosis, life time prediction, partial discharge or material properties are considered in ongoing researches. Specific solutions are worked out depending on the problem and approaches are developed problem-oriented.

The workgroup deals with the regulation of mechatronic systems and components for future power generation and distribution. Besides the efficiencymaximized control of asynchronous machines for controlled drives, like wind turbines, traction drives and special applications, the measurement and numerical characterization and evaluation of regulated electrical drive systems is the emphasis of the group.
