Chapter 2 Magnetic Materials and Their Characteristics

Silicon steel offers high saturation flux density, a relatively good permeability at high flux density, and a moderate loss at audio frequency. One of the important improvements made to the silicon steel was in the process called cold-rolled, grain-oriented, AISI type M6. This M6 grain-oriented steel has exceptionally low losses and high EFFECT OF ROLLING STRAIN ON THE LOSS SEPARATION [[abstract]]The effect of effective rolling strain, in the range 0-0.147, on the core loss, hysteresis loss, eddy current loss, ac and dc permeabilities of a lamination steel has been investigated. It was found that both core loss and hysteresis loss increased with the square root of strain.

Effect of Silicon Content on Iron Loss and Magnetic Domain

It was found that iron loss was reduced as the silicon content was increased, and 6.5 mass% silicon steel showed about half the hysteresis loss of conventional 3 mass% silicon steel, but the eddy Effect of annealing on magnetic properties of Fe/Fe3O4 Mar 25, 2019 · The real part of permeability of the soft magnetic composites could reach a maximal value of 142.9 and a rather low core loss of 274.9 W/kg (measured at 50 mT and 100 kHz). Based on the magnetic loss separation model, the hysteresis loss and eddy current loss coefficient was obtained. Effect of ball scribing on power loss separation of Fe-3 Apr 13, 2016 · Power loss of Fe-3%Si grain-oriented silicon steel was measured after ball scribing with different spacing using a self-designed tool. Three different sections of power loss, including hysteresis loss, abnormal loss, and eddy current loss, were measured and calculated, respectively. The loss variation and ratio were analyzed based on the experimental data.

The loss variation and ratio were analyzed based on the experimental data. Food Packaging Permeability Behaviour:A Report6. Gas Permeability of Silicon-Oxide-Coated Polymer Film and Plasma Pretreatment. In packaging industry, the deposition of amorphous silicon oxide and other ceramics on polymer films is of increasing engineering interest to prevent the permeation through the material of gases like oxygen, carbon dioxide, or water vapour. The barrier films, 10 Influence of temperature on magnetic properties of silicon Mar 13, 2017 · Since the iron loss is composed of static and dynamic component, a natural idea to investigate temperatures influence on iron loss is to study the thermal effect on each loss components respectively. DC magnetic test under different temperatures is carried out because dynamic loss cannot be measured directly. We used the computerized ballistic method 11 11.

Magnetic Properties of Silicon Steel after Plastic

Loss separation analysis has shown that the hysteresis loss is the main contributor to the additional core losses due to sample deformation. Releasing the mechanical load increased the hysteresis loss up to 270% at 10.4% pre-release strain. At this level of strain, the relative magnetic permeability decreased up to 45% after mechanical load Manufacturing Effects on Iron Losses in Electrical Machines0 vacuum permeability [(Tm)/A] r relative permeability [-] A cross sectional area [m2] B ux density [T] B r remanent ux density [T] f frequency [Hz] H magnetizing eld [A/m] H c coercive eld [A/m] I 1 current in the primary winding [A] k ec eddy current loss coe cient W kg(THz)2 k exc excess loss coe cient W kg 1(THz):5 k hyst hysteresis loss Permeability Enhancement in Porous-Sintered the feasibility of lowering the pressure drop of porous sintered reaction-bonded silicon nitrides, permeability tests were con-ducted for specimens with different porosity and pore structure. The results showed that pore former size is a minor factor, while permeability (k) had a strong dependency on the amount of pore former.

Whey separation was negatively correlated with storage modulus ( r = 0.66), and was positively correlated with the maximum loss tangent ( r = 0.63 Separation of CH4/C2H6 Mixture Using Functionalized May 29, 2018 · A gas separation process by 2D structure membranes has recently been considered. Some nanostructure membranes such as graphene have already been used extensively, but silicon carbide nanosheet (SiCNS) capabilities for gas separation have not been studied yet. Due to properties and structure of this nanosheet, it can be used for gas separation with high permeability and
