A method for modelling the magnetic circuits of Maglev systems levitation devices is described, based on 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 the circuit with the improved evaluation of parameters are compared with the results of the clas-sical 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).

Abstract
A method for modelling the magnetic circuits of Maglev systems levitation devices is described, based on 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 the circuit with the improved evaluation of parameters are compared with the results of the clas-sical 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).| File | Dimensione | Formato | |
