ABSTRACT

Homopolar linear synchronous motors (H-LSM) are characterized by a passive long variable reluctance ferromagnetic secondary and a short primary on board of the vehicle that contains an iron core, which hosts both dc coils as long as the core and a three-phase ac winding. H-LSM potentially provides integrated suspension and propulsion functions for the vehicle with a passive iron low-cost, variable-reluctance-solid-ferromagnetic-segmented track. Besides transportation, H-LSM has been proposed for levitated transport in clean industrial rooms. The combined controlled propulsion-levitation properties of H-LSM are obtained at rather good overall efficiency. Passive guideway H-LSM magnetically levitated vehicles, for urban and interurban transportation, should be investigated aggressively that high-performance PWM inverters and mechanical electric power collection in the Mega-Watt power range are available up to 120 m/s and more.
