Our research is oriented towards the problems of small and medium power electrical machines and their special features:

  • Concepts of electromechanical energy conversion / design methodology.

  • Calculation and simulation for the optimization of motors (commutator motors, permanent magnet synchronous machines with sinusoidal and block commutation (PMAC,PMDC), motors for specialized applications)

  • Experimental penetration of electromechanical energy conversion (diagnosis, fault detection)

  • Interfaces to measurement technology and computer science

  • Devices with electromotive drive: household appliances, electric hand tools or automotive auxiliary drives (e.g. windscreen wipers, ABS, window regulators and fans)


Further information


The offered modules lead from the basics of electrical machines over special designs to the design and optimization of electrical machines.


This lays the foundation for independent work on challenging tasks in term papers and theses.
