The analysis of the eddy current, in a rotating disk with an electromagnet is performed in the case of time-invariant field to find the analytical solution. As a method to solve the eddy current problem, firstly, the concept of the Coulomb charge and conformal mapping technique are used with...
The SSPFEM Analysis of Eddy Currents and the Magnetic Fields in the Turbine Generator End RegionA new numerical method called SSPFEM is used for calculation of the magnetic fields and the eddy currents in the end regions of turbine generators. The time varying boundary value problem of the ...
Gradient Coil Induced Eddy Current Computation Using the Boundary Elements Method Commercially available software "Faraday" based on the Boundary Element Method (BEM) [1] was employed for the analysis of 3D eddy currents induced by the whole-body split gradient coil designed by "Magnex Scientific" ...
Iron Disk above a Spiral Coil – A sinusoidal 500 Hz current will be assigned to an eight turn spiral coil underneath of a cast iron disk. The coil induces eddy currents and losses in plate. The 2D model will be setup as shown below using the 2D RZ axisymmetric solver. ...
