Modeling a 3D Eddy Current Problem Using the Weak Formulation of the Convective A-phi Steady State MethodJ. Bird

A 3D model of a magnetic rotor both rotating and translationally moving at high-speed over a conductive guideway is modeled in steady-state using the convective A*-Φ formulation. The presence of the magnetic rotor (source field) is incorporated into the formulation via the boundary conditions. This type of problem is difficult to model using existing commercial packaged electromagnetic software. However, due to COMSOL weak formulation capabilities such models can be implemented relatively easily. The model is compared with experimental measurements.
