ABSTRACT
Passive guideway magnetically levitated vehicles (MAGLEV) are MAGLEV vehicles and industrial platforms whose active parts are all on board of the mover, and full power transfer to the vehicle is required. In counterbalance for a more costly vehicle, the guideway is passive and made of aluminum sheets and back solid iron slabs or of variable magnetic reluctance laminated or solid iron cores. In linear induction motors (LIM) propulsion MAGLEVs, the levitation and guidance are performed in general by dedicated controlled dc electromagnets that interact with solid iron track slabs. The chapter examines the principle and performance of existing LIM and H-linear synchronous motor MAGLEVs with methods to further improve them. It discusses new, potentially competitive, passive guide-way systems such as Transverse-flux linear dc polarized switched reluctance motor MAGLEVs, and multiphase two-level bipolar current reluctance motor MAGLEVs. Permanent magnets-less solution that maintains the transverse-flux topology but simplifies the guideway laminated segments stems from the dc-polarized linear switched reluctance motor.
