Abstract
This paper presents a methodology for identifying a novel iron loss model and segregating the different loss components from measurements on a single sheet tester with alternating and rotating fields. The eddy current losses are first extracted with a 1D numerical approach and the hysteresis and excess losses are then estimated with an analytical method that allows the separation of alternating and rotational hysteresis as well as excess losses. The elaborated iron loss model can be applied in case of distorted flux density and on a wide range of frequencies. The identified model is further applied in the time-stepping computation of an induction motor in view of better estimation and segregation of iron losses. The results of no-load simulations at different voltage levels are in good agreement with the measured ones. All presented computations and models are validated experimentally too.
