Laboratory of the Chair of Electrical Machines and Drive Systems
The electric machine laboratory consists of a workshop with a 5t assembly crane. Via a driveway and floor hatches, devices with large dimensions and weights can be transported into the hall. In the laboratory, 12 clamping plates for experimental setups are available.

The power supply of the test stands is provided by rotating converters located in the basement and a three-phase power supply per workstation. The distribution to the test benches is done via a crossbar distributor. Furthermore, a number of static converters are available for the test benches.
Rotating converters:
- 3 Phase power supply, rating 3 x 63A
- 3 phase variable transformer 0 – 500V, 50kVA
- DC 0 – 440V, 50kW
- Frequency converter 100 – 500Hz, 20 – 500V, rating app. 50kVA
- Frequency converter 15 – 100Hz, 20-500V, rating appr. 50kVA
Static converters:
- Bidirectional 3-phase power supply 10 – 1000Hz
- DC power supply 0 – 500V, 0 – 600A up to 40kW
- 3 phase power supply 45 -5000 Hz, 15kVA
- 3 phase power supply realized by a linear amplifier 0 – 30kHz, up to 15kVA
- Several electronic loads for DC
- 4-Quadrant linear amplifier (Hubert), 250W, 2 channels 0 – 1MHz
