YGP-6252 # Magnetic Levitation Experiment

Magnetic levitation technology is a quintessential mechatronic discipline, integrating electromagnetism, electronic technology, control engineering, signal processing, and dynamics. The advancement of electronic technology, control engineering, signal processing, electromagnetic theory, and novel electromagnetic materials has propelled magnetic levitation technology forward, enabling its widespread application in numerous fields. These include maglev trains, active magnetic bearings, magnetic levitation balances, magnetic levitation transport equipment, magnetic levitation measuring instruments, and magnetic levitation robotic wrists, with maglev trains being the most prominent example. The operation of a maglev train primarily comprises levitation and propulsion subsystems. This experiment focuses on the levitation subsystem and its control. The experimental setup facilitates large-range adjustable stable magnetic levitation, which eliminates external force interference during testing and allows for accurate measurement of system equilibrium characteristics.
