Magnetic Properties of Double Grain-Oriented Steel Sheets in Rotational Flux Conditions.

Comparative Harmonic Loss Measurement of Grain Oriented and Non-oriented Magnetic Sheets Using a High Precision Single Sheet Tester

 Abstract: Local flux may be distorted in many regions of core, although total flux is usually sinusoidal. When attempting to predict the loss distribution in materials operating under localized distorted flux conditions, which occur in machines and transformer cores, it is essential that proper account of the waveform be taken. Moreover for development of new magnetic materials and generation ...

Electroless Co–P-Carbon Nanotube composite coating to enhance magnetic properties of grain-oriented electrical steel

The effect of Co–P-CNT coating on the magnetic properties of grain oriented electrical steel was investigated. To analyse the coating, Raman spectroscopy, Superconducting QUantum Interference Device (SQUID), single strip testing, Scanning Electron Microscopy (SEM) and talysurf surface profilometry were performed. Raman spectra showed the D and G band which corroborates the presence of Multi-Wal...

Magnetomechanical Damping and Domain Structures in Grain Oriented Silicon Steel Sheets

Study of Secondary Recrystallization in Grain-oriented Steel Treated under Dynamical Heat Treatment Conditions

Grain oriented silicon steel (GO) is mainly used as the core material in transformers, and it is the only product manufactured in the steel industry that applies the secondary recrystallization phenomenon. Its magnetic properties are closely related to the secondary recrystallization texture, i.e., the sharpness of 110 (001), Goss texture 1 . This sharp texture develops due to a discontinuous o...

Analytical Model for magnetic Anisotropy Dedicated to Non-Oriented Steel Sheets

Recent investigations on magnetic properties of Non-Oriented steel sheets enhance the comprehension of the magnetic anisotropy behaviour of widely employed electrical sheets. Our investigation consists of developing an analytical model to consider these magnetic properties while modelling electromagnetic systems. From rotational measurements, the anhysteretic curves are interpolated in order to...
