ELECTROMAGNETIC OPTIMIZATION OF EMS-MAGLEV SYSTEMS

In EMS-MAGLEV high-speed transport systems, devices for propulsion, le vitation and contactless on-board electric power transfer are combined in a single electromagnetic structure. The strong coupling among the windings affects the performance of each device and requires the utili zation of numerical codes. The paper describes an overall optimization procedure, based on a suitable mathematical model of the system, whic h takes into account several items of the system performance. The para meters of the model are calculated by an automated sequence of FEM ana lyses of the configuration. Both the linear generator output character istics and the propulsion force ripple are improved applying the proce dure to a reference configuration. The results are compared with the r esults obtained by a sequence of partial optimizations operating separ ately on two different subsets of the geometric parameters.
