Field-circuit integrated methodologies for design and modelling of permanent magnetic levitation devices for Maglev transportation systems
A method for modelling the magnetic circuits of Maglev systems levitation devices is described, based an an improved analytical evaluation of the interactions at the air-gap among the pole shoes and the stator structure and on the interactive use of circuit and field analysis, by means of FEM codes. The results of rite circuit with the improved evaluation of parameters are compared with the results of the classical circuit and of the FEM investigation. The application of this model to the design and operation analysis of a hybrid levitation device is discussed (levitator with permanent magnet excitation and current stabilization).
