An Accurate Iron Core Loss Model in Equivalent Circuit of Induction Machines

An Accurate Iron Core Loss Model in Equivalent Circuit of Induction Machines

Iron core loss is the major loss in electrical machines. It performs up to 25% of total machine losses. The machine efficiency calculation requires an accurate prediction of losses. The accuracy of losses calculation depends largely on the equivalent circuit parameter determination and measurements....
