Uncertainty of the magnetic flux linkage measurements performed by modified current decay test

Abstract

The paper presents the estimation methodology for uncertainties of magnetic flux linkage measurements, when the flux linkage and current functions with respect to time are obtained instead of single values of these quantities. The computed uncertainties are then used to estimate the quality of an approximation of a current-flux characteristic in the mathematical model of an electrical machine when the approximation is based on the results of measurements.
