Students during their practical course in the lab

Laboratory: Room 1.E.22-28

Teaching

Practical course: Electromechanical Energy Conversion II (BET)

The following experiments are part of the practical course Electromechanical Energy Conversion II:

Testing of electrical machinery
Operating behaviour of DC machines
Three-phase transformer
Synchronous machine
Mains-powered asynchronous machine
Sampling and digital signal processing
Asynchronous machine at the frequency converter
Grid behaviour of a wind power plant with guided tour

Focus topics of research and development

The test stands in our two long-term testing rooms are designed in a mostly universal way, and can be used to test newly developed drives and prototypes up to 80 kW, an RPM of 13,000, and a (peak) torque of up to 150 Nm.

In cooperation with regional companies, several projects in the areas of simulation and development of electric drives are implemented. The research activity is explained in detail on the website of the TTZ-EMO under the section “Electrical machinery”.

Equipment

Students visiting a laboratory with their supervisor

Among other equipment, the lab offers

Three sets of transformers for providing two adjustable three-phase voltage grids with frequencies from 17 to 100 Hz and one direct voltage grid with up to 1000 V / 80 A.
Programmable three-phase voltage source
Laboratory power supply units for (DC) voltages up to 300 V and currents up to 20 A.
2 rooms for long-term testing (no air conditioning)
Test stand for small drives < 300 W
Several highly precise torque and rpm sensors (deviation < 0.1 %)
State-of-the-art measuring devices (digital memory oscilloscopes, power measuring devices ...)
Several workstations based on Xeon E5 (18 cores), as well as standard Intel i7 (10 cores)
Standard devices like oscilloscopes, (small) power supply units, function generators, etc.
