Abstract

The traceability of torque measurements on test benches for electrical machines is primarily established by the static calibration of a torque transducer. However, the loading conditions and signal processing methods are generally different for the static calibration and the measurement on a test bench. Therefore, the applicability of the calibration should be clarified before applying the calibration results for further analysis. In this paper, the torque measurement chain using a power analyser on a test bench for electrical machines is compared to the measurement chain used in the standard calibration procedure DIN 51309.
