    摘要： An active control system for a mass traveling along a guideway and method for active control of a mass traveling along a guideway. The active control system includes at least one displacement sensor and at least one motion sensor. Signals from the at least one displacement sensor and the least one motion sensor are processed to adjust a displacement of a reference location on the mass from a fixed reference.

    摘要： Described herein is a magnetically levitated linear transportation stage which utilizes a permanent magnet bias flux to generate a passive magnetic/suspension force/torque in a first set of directions orthogonal to a direction of transportation stage travel, a motor flux which forms a traveling wave along a direction of transportation stage travel and a suspension control force orthogonal to the direction of transportation stage travel. Such a magnetically levitated linear transportation stage is suitable for use in in-vacuum transportation tasks such as in conjunction with photo lithography systems (e.g. extreme ultra violet (EUV) machines).

    摘要： Transport apparatus having at least one levitation generator and at least one drive generator. The at least one levitation generator configured to generate a levitating magnetic flux, move within a corresponding at least one lifting member, and elevate above a rest position relative to the at least one lifting member in response to the levitating magnetic flux. The at least one drive generator configured to generate a driving magnetic flux, move within a corresponding at least one drive member, and laterally move relative to the at least one drive member in response to the driving magnetic flux. At least a portion of the at least one levitation generator is movable relative to the at least one drive generator.

    摘要： A hybrid electrodynamic levitation system that utilizes both superconducting and conductive tracks. The hybrid system reduces the overall drag induced upon the system and reduces the amount of power required to achieve operating speeds, while resolving the issue of requiring velocity relative to the track for levitation. The total initial and operating costs of the hybrid system can be lower than utilizing a superconductive or conductive track alone, while still enabling a fail-safe levitation system for high speed transportation.

    摘要： The present disclosure in some embodiments provides a method for controlling a magnetic levitation object, including steps of: receiving, by a magnetic levitation seat, angular offset information from the magnetic levitation object; determining, by the magnetic levitation seat, an offset angle of a center of gravity of the magnetic levitation object relative to a central magnetic point of the magnetic levitation seat in accordance with the angular offset information; and adjusting, by the magnetic levitation seat, a magnetic force from a corresponding region of the magnetic levitation seat in accordance with the offset angle.
