Abstract
This research presents a method for the simulation of the
magneto-mechanical system dynamics taking motion and eddy currents into
account. The major contribution of this work leans on the coupling the
field-motion problem considering windings as the current forced massive
conductors, modelling of the rotor motion composed of two conductive
materials and the torque calculation employing the special optimal
predictor combined with the modified Maxwell stress tensor method. The 3D
model of the device is analysed by the time stepping finite element
method. Mechanical motion of the rotor is determined by solving the second
order motion equation. Both magnetic and mechanical equations are coupled
in the iterative solving process. Presented method is verified by solving
the TEAM Workshop Problem 30.
