The author in his research focuses however on electrodynamic levitation systems. The system does not need any power supply to sustain levitation neither on the vehicle side nor on the track side. Electrodynamic levitation is based on arrays of permanent magnet in Halbach arrays mounted underneath the vehicle and conducting slabs mounted along the tracks. Levitation occurs as a result of vehicle movement. Then currents, that are induced in the track, are repel permanent magnets.
The author during his research work conducted numerous series of analytical calculations and simulations with the usage of FEM programs. The goal is to design the most energetically effective arrangement of permanent magnets and conducting track that would stably lift the traveling vehicle while generating very low dragging force especially when travelling with low speeds. The author found an novel Halbach array arrangement allowing to decrease the power consumption of the EDS systems up to 15%.
