The distortion analysis of magnetic excitation (DAME) method has been recently proposed to facilitate magnetic measurements for non-destructive testing in which pick-up coils are not necessary. (PDF) Electric and Magnetic Field Galvanic Distortion The study by Chave and Jones (1997) also includes the analysis for magnetic field distortion, with which the data still could not be fitted to a 2D model, and further strengthens the suggestion of

Aug 15, 2017 · The magnetic field can be equivalent to the axial flux path. It can be noted that airgap magnetic field under the same phase winding is reduced. The magnitude of the resultant airgap magnetic field will be regulated by means of adjusting the current value of dc winding. 3. Design principle and procedure3.1. Design principle Analysis of the voltage drop across the excitation coil Apr 01, 2021 · The distortion analysis of the voltage drop across the excitation coil, the v d-H method, proposed here facilitates a quicker and simpler magnetic characterization of skin passed samples than the conventional magnetic methods of , , , , , , , , , , which require low excitation frequency and complex and expensive instrumentation. The proposed method analyzes the voltage measured in the excitation Distortion Analyzer a New Tool for Assessing and nonlinear system producing additional distortion components in the output signal [1 17]. To assess the nonlinear behavior quantitatively we usually apply spectrum analysis to evaluate the harmonic or intermodulation components in the output signal for multi-tone excitation input.
Neutron scattering experiments on La2x Sr x CuO4 (LSCO) have revealed the incommensurate antiferromagnetic peaks do not lie exactly on the symmetry axes (q x=± and q y=±), but, are slightly shifted from them. In this paper, a scenario is presented for such shift in terms of the anisotropy of t (next-nearest-neighbor hopping integral on the square lattice) in the slave-boson Modeling and Analysis of the Synchronous Generators Modeling and Analysis of the Synchronous Generators Excitation Systems Vadim Slenduhhov, Jako Kilter step-up transformers protection from excessive magnetic flux due to low frequency or overvoltage. Excessive magnetic flux prevent parameters distortion because of them. Excitation system ceiling voltage is the maximum voltage Moorthy V. Distortion analysis of magnetic excitation - a 2. Principle of distortion analysis of magnetic excitation The total voltage (V T) applied is divided into the voltage across the excitation coil (V E) and that across any current limiting resistor (V RCL) in series in the circuit. It is known that the magnetic induction will affect only V E which consists of resistive component due to coil
Abstract. Distortion Analysis of Magnetic Excitation (DAME) is a novel and simple measurement approach for evaluation of different properties of ferromagnetic materials. The presence of a different ferromagnetic material, between the poles of an electromagnetic (EM) yoke, introduces non-linear distortion in the excitation voltage
