Modeling of hysteresis loops may be useful for the designers magnetic circuits in electric machines. The present paper focuses on possibility to apply Harrison model describe grain-oriented electrical steel subject compressive stress. extension is achieved by introduction an additional term into equation that describes irreversible magnetization process. does not include a product stress and ma...

A method using electropulsing to separate inclusions from molten steel is developed, based on the differences in electrical properties between the inclusions and liquid metal. The inclusions have different electrical resistivity from that of the liquid steel and hence being expelled to the surface of the metal by electropulsing. In comparison with the as-solidified untreated steel, the size of ...

In the manufacturing process of electrical machines, laser cutting is widely used to produce laminations cores. The internal stresses introduced by high-energy beam will lead deterioration in magnetic properties non-oriented silicon steels. To accurately predict core losses it important analyze degree and mechanism steel sheets caused cutting. this paper, first, local 35WW250 at different posit...

Dry reforming of methane (DRM) has been investigated under an electronactivated catalytic bed in a thermo-electrical reactor. The main objective of this work was to investigate what the impact of the electrical current on the conversion of methane is. The combination of thermal and electrical energy allowed achieving higher conversions for both reactants at temperatures varying from 850–950°C. ...

The effect of uniaxial stress on iron losses M400-50A grade non-oriented electrical steel sheets cut by punching process is experimentally studied. Samples along the rolling and transverse directions having different number cutting edges are used for this purpose. Measurements carried out in range 10–100 Hz frequency sinusoidal excitations at magnetization levels under varying using a single sh...

Grain oriented steels are widely used for electrical machines and components, such as transformers reactors, due to their high magnetic permeability low power losses. These outstanding properties the crystalline structure known Goss texture, obtained by a suitable process that is well-known in widespread use among industrial producers of ferromagnetic steel sheets. One most interesting research...
