Improved Analytic Model for Eddy Current Force Considering Edge-effect of a Conductive Plate
Electrical Machines (ICEM), 2016 XXII International Conference on
The eddy current induction in a conductive medium with finite width and thickness due to a moving magnetic rotor is studied. The presented formulation is based on the second order vector potential and the magnetic scalar potential and takes into account the magnetic field interaction through the edges of the conductive medium. The eddy current fields as well as thrust, lift and lateral force created by the rotational motion of the magnetic rotor have been computed and the accuracy and computation time have been compared with steady-state and transient finite element analysis results.
