Quantification of iron losses for eddy current estimation in clamping plate

Clamping devices are subject to losses by eddy currents due to end effects. However, it is quite difficult to quantify them. In order to study the effect of different clamping materials, an experimental bench has been built up while the losses are determined by subtracting iron losses. The latter are deduced from 3D FE calculations and thus the BH curve has to be approximated with care at low magnitudes to account for the effect of the frequency. This paper deals with the quantification of the iron losses in the case of the studied experimental bench.
