Magnetically-Levitated Transporter
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).
System and method for improving travel across joints in a track for a linear motion system
A system for determining the position of a mover as the mover transitions between segments along a track includes a first controller on a first track segment and a second controller on a second track segment. The first and second track segments are adjacent to each other and a junction is located between the two segments. The first and second controllers are in communication with each other and share a locally determined position value with the other controller. Each controller determines a compensated position value as a function of both a locally determined position value and the shared position value received from the other controller. Each controller utilizes the compensated value of the position value as determined on that controller to control operation of the mover while it is present on the corresponding track segment.

Segmented track for a Maglev vehicle
A segmented track for a Maglev vehicle includes a structural support portion and a Maglev portion fastened to the structural support portion. Each segment of the structural support portion is formed by fusing together three cast metal components. Neighboring ones of the structural support segments are joined together end-to-end by fused metal, and neighboring ones of the reaction rail segments are joined together end-to-end by fused metal. The positioning and joining of the successive segments is done in the field using on site jigs and machines.
