ELECTRO-MECHANICAL DESIGN OF A MAGNETIC GEAR PROTOTYPE

A magneto-mechanical approach is proposed to design a magnetic gear prototype. Firstly, an integrated tool for electromechanical simulations is developed, starting from a topological parametric model of a planetary magnetic gear (PMG). Then a CAD model is realised with a progressive rise in complexity, in order to achieve quickly exchangeable configurations for different experimental tests. Three different solutions are designed with advantages and drawbacks. Finally, a block-oriented dynamic model of a PMG, inserted in a mechanical driveline, is developed in Matlab/Simulink environment using the results of magneto mechanical simulations, to virtually test the dynamic behaviour of the device.
