This paper proposes an improved dynamic E&S vector hysteresis model to increase modeling accuracy especially for non-elliptic B-waveforms, and its implementation to finite element method. The major improvements of the suggested model are on the determination of the geometric parameters of a non-elliptic B-waveform, and the calculation of the magnetic reluctivity and hysteresis coefficients. The proposed model is combined with FEM and applied to the iron loss analysis of a three-phase transformer.

AbstractThis paper presents magnetic flux density behaviour in laminated electrical sheets which affects the results and precision of iron losses calculation in imbedded permanent magnet (IPM) machine. Objective of the research was to analyse all the influential phenomena that were identified through iron loss models analysis, finite element method simulations and iron loss measurements. The presence of phenomena such as harmonic content and rotational magnetic fields are confirmed with finite element method analysis of concentrated and distributed winding IPM machine. A significant magnetic flux density ripple in the rotor of concentrated winding IPM machine in comparison to distributed winding IPM machine is revealed and analysed. Behaviour that affects iron loss in the rotor of synchronous machines in the absence of first order harmonic is analysed. The DC level added to alternating magnetic flux density was used in experiment to mimic magnetic behaviour on the rotor of IPM machine and further to calculate iron losses.
