MEASUREMENTS OF MAGNETIC PROPERTIES OF ELECTRICAL STEEL SHEETS FOR THE AIM OF LOSS SEPARATION

Wojciech A. Pluta

   Magnetic loss separation is an excellent tool for loss mechanism evaluation thogether with ferromagnetic material and electrical machines optimisation and modelling. Therefore, it is very important to perform loss separation so precisiely as possible. Samples of non-oriented and grain-oriented electrical steel have been tested in non standard Single Sheet Tester at ten different frequencies. Specific total loss was measured and than separated into hysteresis, classical eddy current and additional eddy current loss components. The aim of this paper is to provide a contribution to the better understanding of magnetic losses phenomena in soft magnetic materials.

Keywords: loss separation, hysteresis loss, eddy current loss, additional loss
