Design of an Electrodynamic Levitation System with COMSOL Multiphysics® Software
Levitation has found important applications in several areas of engineering, from microgravity to transportation systems. Electrodynamic levitation consists of the interaction of a varying in time magnetic field – provided by an alternating voltage supplying a coil or a moving permanent magnet. The main applications of this technique are MagLev trains and magnetic bearings. The electrodynamic experimental system was developed at Universidade Federal do Rio de Janeiro (UFRJ) with objective of achieve suspension of two conductor rings – aluminum and copper – supplying alternate voltage at a coil with grid voltage of 127 Vrms. The COMSOL Multiphysics® software was used to provide the system configuration solution. The AC/DC Module was chosen because of its magnetic fields physics interface. In the developed model, the induced magnetic field and the electromagnetic force produced in both rings were analyzed.
