To ensure that the test rig was readily available, the chosen drive concept had the following advantages:
- No matching gears,
- No adjusting devices,
- High-precision torque measurement:
- HBM T10FM torque flanges
- HBM Z4A force transducers
- HBM PME/MP60DP and MP30DP amplifiers
- Low connection power:
- Despite the high power rating for the installed machines of 5,540 kW, it was possible to limit the AFE line-side converter to 2 x 800 kW. This also guarantees dynamic operation.
