“…This can be interpreted to the effect of ILFs on energy loss components. In the recent study performed by the author [4], it was experimentally proved that ILFs do not affect the hysteresis energy loss. Based on the TSM of ( 6) and ( 7), dynamic energy loss of GO steels is directly proportional to 𝑑𝐵 𝑑𝑡 ⁄ .…”

“…Magnetic hysteresis loops may take a variety of different forms which depend on magnetising regime, magnetic and electric properties of the materials, and quality of the cores. Experimental and analytical approaches based on the hysteresis phenomenon have been previously developed by the author for core quality assessment, under sinusoidal [4,11] and nonsinusoidal excitations [32]. To study impacts of the artificial faults on the hysteresis behaviour, DHL of the test samples were measured for the range of magnetisation; the results under sinusoidal induction of 50 Hz and peak flux densities of 1.0 T to 1.7 T are shown in As a phenomenological impact of ILFs on the hysteresis performance of the magnetic cores, Figs 9 and 10 show that peak magnetic field strength Hm* is remarkably increased by increasing number of the shorted laminations, which has a direct impact on total energy loss per cycle.…”

“…It is well distinguished that edge burr has destructive impacts on quality of the electrical steels and hence the assembled magnetic cores. Electrical contact with low resistance and hence inter-laminar fault (ILF) between the adjacent laminations have been identified as major consequences of edge burr [4][5][6][7][8][9]. ILFs problem could also arise during the operation of the devices due to a number of reasons, e.g., vibration of loose strips or windings, arcing from winding failure, mechanical stress due to electrical short circuits, tensional/compressional stress during transportation or earthquakes in earthquake-prone regains [7][8][9][10][11].…”

Hysteresis phenomenon is a distinctive approach to describe natural behaviour of the magnetic materials and magnetic cores. This paper proposes a phenomenological approach for core quality assessment and condition monitoring of magnetic cores with grain-oriented electrical steels. The developed technique is based on the hysteresis phenomenon and interpreting the most distinctive parameters of the measured dynamic hysteresis loops. In this study, artificial short circuits were introduced between the laminations of stacks of two, three and four Epstein size strips of Fe-3 wt % Si grain oriented steel. The results showed that, condition monitoring of the magnetic cores can be effectively performed by measuring and analysing the hysteresis loops.

Real-time magnetic core condition monitoring is a promising solution for rapid fault detection. However, similar to dimensioning or performance evaluation, this monitoring has always been performed through averaged magnetic properties, which limits efficiency. In this domain, significant progress is forecasted by achieving precise local measurements. In this study, an innovative solution is proposed to measure local magnetic properties, which is adapted to real-time monitoring and magnetic circuit evaluation. The proposed sensor is a one-piece device that is flat enough to be placed noninvasively between the laminations at distinct positions in the magnetic core. It measures the magnetic excitation and induction fields in two dimensions, which can be used as local inputs for realtime condition monitoring. In this manuscript, the proposed sensor was first detailed, experimental results were provided, and finite-element simulations were performed. The sensor capability was validated both experimentally and through simulation. The results of this study contribute to the development of an intelligent magnetic core that includes an effective real-time monitoring system. The study provides a local validation of the most advanced highfidelity simulation method, which could be used to predict the responses of magnetic cores and electromagnetic converters to defects of various natures, as well as geometrical and property changes.

This paper proposes an advanced approach to construct static hysteresis loop of Grain-Oriented (GO) electrical steels for dynamic modelling and energy loss analysis. The proposed approach is in line with the magnetic hysteresis and phenomenological concepts of ratedependent and rate-independent energy loss components of ferromagnetic materials under time varying magnetic fields. The proposed method can predominantly describe energy loss mechanism and magnetization processes of the material. Accuracy of this technique was validated on Epstein size laminations of 3 % GO silicon steels. The results explicitly confirmed the effectiveness of the proposed method in dynamic hysteresis modelling of GO electrical steels at magnetizing frequencies up to 1 kHz and peak flux densities up to 1.7 T.
