Prognozowanie strat w stalach elektrotechnicznych przy kontrolowanym sposobie magnesowania
Języki publikacji
Abstrakty
The efficiency of electrical machines depends very much on the choice and proper usage of soft magnetic materials in the magnetic properties of electrical steels and the availability of competing materials give machine designers opportunities to improve the performance of existing classes of machine and to consider new topologies to exploit the material advances. In this paper a brief review of materials available today is followed by a focus on the characterisation of electrical steel which is by far the largest family of soft magnetic materials. Traditional methods of measuring losses are reviewed and drawbacks in today's requirements are noted. The challenge of characterising steels under the complex magnetising conditions found in machine cores is reviewed and present trends in measurement and prediction of iron loss are discussed.
Efektywność maszyn elektrycznych zależy od prawidłowego doboru materiału magnetycznego. Postęp w dziedzinie materiałów magnetycznie miękkich i bogata oferta rynkowa tych materiałów stwarzają konstruktorom nowe możliwości poprawiania jakości istniejących rozwiązań konstrukcyjnych maszyn elektrycznych oraz tworzenia nowych projektów. W pracy przedstawiono przegląd nowych materiałów magnetycznie miękkich. Tradycyjne metody badania strat tych materiałów nie zawsze dają dobre wyniki. Opisano nowe metody badania strat przy złożonych warunkach magnesowania oraz przedstawiono kierunki rozwoju w tej dziedzinie.
