Premises at Kesslerplatz (Building KA) and “Auf AEG”

Building KA houses a number of laboratories in which work is carried out in connection with a diverse range of projects.

Alongside “Auf AEG”, they also handle the fields of electrical machines and mechatronic drive systems.

The Power Electronics Laboratory in Room KA.136 is equipped with laboratory benches and safety enclosures. Power connections providing up to 250 A are available. This is where power electronic systems and components are developed and tested, including their control and regulation.

There is an additional laboratory on the ground floor (KA.036), which is equipped with a number of test chambers that are used for the initial operation, testing, and optimization of the systems developed in the Power Electronics Laboratory. The equipment provided is geared in particular towards the measurement and evaluation of a diverse range of parameters and scales. The building also houses a workshop for the manufacturing of mechanical components. Two further laboratories (KA.132 and KA.126) primarily handle the control and regulation of power electronics systems and circuit board unbundling.

Standort Kesslerplatz

The Energie Campus Nürnberg (EnCN) is a structural funding project of the Free State of Bavaria, established with a view to boosting the business sector and the energy industry in Nuremberg. The Energie Campus is split into ten individual projects. The drive systems group chaired by Prof. Armin Dietz, which forms part of the “PROCESS” subproject at the Energie Campus Nürnberg, is conducting research in the field of energy-efficient drive system and machine designs. Within the scope of this subproject, three drive system test rigs have been built with different performance classes. The measuring equipment available includes high-precision power, current, and voltage measurement systems for the purposes of determining losses and efficiency. The research activities carried out primarily revolve around minimizing losses from electrical machinery and improving the efficiency of mechatronic drive trains.

The current trend in rotating electrical machines is tending towards a higher power density and increased compactness. As a result, the magnetically soft materials contained within electrical machines achieve extremely high magnetic flux densities. The ELSYS Institute has established a measuring station for the purposes of determining the magnetic properties of materials used in the field of electrical engineering. One of its special features is its ability to use currents of up to 300 amps in order to determine the magnetic field to ensure that the magnetic flux densities of modern machines can be handled. Two Epstein test frames and a single strip tester with the optional application of mechanical compressive and tensile stresses are available for use. Ring magnetization is possible under both AC and DC magnetization.
