3-D Eddy Currents Analysis in Orthotropic Materials Using Truncated Region Eigenfunction Expansion Method

Abstract:

A model for 3-D eddy currents analysis in orthotropic materials such as CFRPs is proposed. With artificial magnetic insulation boundary conditions, we solved a vector differential equation which describes the magnetic vector potential in the CFRPs materials with a delta coil near it using the method of separation of variables. As a result of the truncated region eigenfunction expansion method, a series solution was obtained, from which we got the eddy currents distribution. The distribution shows a good agreement with the work by others.
