A magnetic repellent type conveyor system is proposed as a new application of repulsive type magnetic bearings, which use repulsive forces between the stator and the permanent magnets of the rotor. The proposed conveyor is comprised of the alignment of many passive magnetic levitation units. Each unit also contains electromagnets to oscillate a levitator shaft in the radial direction. The manner of generating vibration and rotation in the transport direction was examined by the various excitation methods.
The design of a new transport system presupposes a deep understanding of the dynamics of the system. This article presents a simulation environment to analyze the dynamic behavior of a magnetic levitation vehicle designed to carry baggage at airports. The simulation environment is built in a modular way so that it can be easily expanded. The carrier vehicle is modeled as a rigid body with 6 degrees of freedom. The Newton / Euler equations of motion provide the basis of the mechanical model. Two models of support magnets are presented: a simple analytical model and an accurate model based on finite element calculations. The levitation controllers, based on a state control algorithm, complete the simulation environment. Simulations with different air spaces and / or loads, as well as rides through curves are possible. The extensive simulation results demonstrate the usefulness of the simulation environment in the design of a new transport system.
