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.

- 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
