Abstract :
It is possible that a high-temperature superconducting (HTS) bulk linear synchronous motor (LSM) can be propelled contactlessly with no guidance and levitation control. Its design and dynamics simulation are based on very complicated analysis of HTS bulk. This paper proposes HTS bulk LSM applied to ropeless linear elevator analyzed numerically taking into account the electric field-current density (E-J) characteristic in finite-element methods. The LSM can be propelled following command motion pattern with proportional-integral-derivative control and producing stable guidance force without its control.
