Rotational core loss data improve the accuracy of estimating electric machine core losses. The losses are measured using magnetizing yokes, which generate a rotating field. The accuracy of the measured losses is dependent on the uniform distribution

Rotational core loss data is required for core loss estimation in electrical machines. This necessitates the design of 2D magnetizers to accurately measure these losses. However, the accuracy of any 2D magnetizer is contingent on its ability to maint

An ac loss measurement based on the null calorimetric technique and another based on the electrical technique were performed in situ on the same sample. The results show good agreement and although the electrical technique is faster and provides a sl

AC losses are measured using the null calorimetric method on a silver–gold sheathed Bi-2223 tape. The dependencies on current and on frequency give the usual results, showing the predominance of hysteretic losses. After damaging the tape, the same

A new calorimetric method for a.c. loss measurements in superconductors has been developed over the last few years, based on a null detection heating method. The measurements have shown general agreement with theoretical predictions and with values o

The use of high-temperature superconductors (HTS) in some power utility applications requires long lengths of conductors with low AC losses and good mechanical properties. This is typically obtained by making multifilamentary wires with thin filament

A new calorimetric method has been developed to measure ac losses in superconductors. Calibration of the losses requires a reference heater of the same size and shape as the superconductor mounted in a symmetric environment. Its main advantage is the
