概要:
The electromagnetic pump proposed by the authors is concerned with the magnetic shielding effect of eddy currents in a c
…
onductive plate. In this paper we use FEM analysis to examine the shape of a copper plate for controlling eddy currents, and compare our findings with measured results. The proposed T-shaped plate improves shielding and reduces eddy-current losses compared with existing pumps. We also confirmed an improvement of the thrust force when used in a closed system for circulating a liquid alloy. © 1993 IEEE.

概要:
This paper presents a new 3-dimensional finite element analysis to ac electromagnetic machines with nonlinear magnetic characteristics in a steady state. The method enables us to calculate the time-periodic (non-sinusoidal)
…
characteristics in harmonic domain. Unlike the field calculations in time domain, we can obtain only the steady-state solution directly. The application of the parallel processing to this approach is discussed. The analyses of the inductor with shading coil and the model of the flux-concentration type electromagnetic pump are presented.

概要:
In this paper we propose a model to reproduce a PCS pattern eddy current testing signal based on 3D FEM package and scanning simulation. In this method we consider some common PCB elements as test pieces while a simple Meander-type
…
coil is utilized as excitation coil above the elements. Numerical solution to the above problem with the help of a 3D FEM provides the magnetic flux density in the region above the PCB test elements. Shifting the test element's position step by step and repeating the numerical calculation for each of the test elements new positions, the scanning process of a PCB test piece is simulated. Analysing and smoothing the magnetic field data from all of the aforementioned steps provide the final PCB pattern signal. Image processing technique was applied to obtain the PCB part image.<br />Special Issue on 16th MAGADA Conference

概要:
Plasma reactors demand unique requirements of their power sources such as high-voltage output, variable frequency and a current limiting capability. This paper shows a new means of providing power to a plasma reactor based on a
…
magnetic frequency tripler and transformer. The integration of the tripler and transformer allows one to obtain improved operating characteristics and power utilization compared to othr conventional types of power sources.
