Magnetic Load Cell with Oriented Silicon-Iron Steel Laminations

Magnetic Anisotropy in Silicon Iron

The first anisotropy constant for Fel-%Si, is determined by torque measurements, for x up to 10 atomic per cent, in the temperature range 21-300 OK. The values, as extrapolated to 0 OK, vary linearly with silicon content. Using the expressions obtained by Keffer and Oguchi it is shown that K1 at 0 OK should vary as { 1 (a + 2) x ) where a is the ratio of dipole contribution to the total value o...

Power losses in thick steel laminations with hysteresis

Residual Stress Distribution in Grain-oriented Silicon Steel

We investigated the residual stress distribution in a grain of laser-irradiated and gearrolled grain-oriented Fe-3%Si silicon steels by X-ray stress measurement method in order to clarify the effect of residual stresses on magnetic domain refining. Dotted cavity lines were formed by Nd:YAG laser with a power density of 3.3 mJ/pulse for the laserirradiated sample. By using a newly developed X-ra...

Evaluation of tissue doppler echocardiography and T2* magnetic resonance imaging in iron load of patients with thalassemia major

Background: Iron-mediated cardiomyopathy is the main complication of thalassemia major (TM) patients. Therefore, there is an important clinical need in the early diagnosis and risk stratification of patients. The aim of this study was to evaluate the efficacy of tissue doppler imaging (TDI) to study cardiac iron overload in patients with TM using T2* magnetic resonance (MR) as the gold-standard...

Homogenization of Quasi-static Maxwell's Equations

This paper studies the homogenization of quasi-static and nonlinear Maxwell’s equations in grain-oriented (GO) silicon steel laminations. GO silicon steel laminations have multiple scales and the ratio of the largest scale to the smallest scale can be up to 106. Direct solution of three-dimensional nonlinear Maxwell’s equations is very challenging and unrealistic for large electromagnetic devic...
