Classical core loss models such as two components model or modified Steinmetz model are still popular and used by engineers to loss prediction in electrical machines. They may carry to increase discrepancy between calculated and measured values. This discrepancy increases with grain-orientation and with increasing discrepancy from sinusoidal magnetisation conditions. Statistical loss model shows better applicability for loss calculation however, it requires many measurements in frequency domain what is troublesome. The paper presents the frequency behaviour of classical and statistical loss models in grain and non-oriented electrical steel sheets.

Klasyczne modele strat są wciąż popularne i wykorzystywane przez inżynierów do przewidywania strat maszyn elektrycznych. Mogą one prowadzić do niezgodności pomiędzy obliczonymi i zmierzonymi wartościami strat. Niezgodność wzrasta ze zwiększeniem orientacji ziaren i odkształceniem od sinusoidalnego kształtu strumienia magnetycznego. Statystyczny model strat wykazuje lepszą stosowalność do obliczenia strat jednak wymaga czasochłonnych pomiarów w dziedzinie częstotliwości. Artykuł przedstawia właściwości częstotliwościowe klasycznych i statystycznych modeli strat w zorientowanych i niezorientowanych blachach elektrotechnicznych.
