ABSTRACT:
Normal and superconducting magnets are employed in an electromagnetic (attractive) suspension system for MAGLEV vehicles. The super conducting magnet provides the principal magnetomotive force (MMF) to the system while the normal electromagnet compensates for dynamic or transient loads on the system that vary the suspension gap. The rapid variations are slowly compensated for by the superconducting magnet thereby minimizing heat generation by a superconducting coil.
