High-precision ‘flying carpet’

Since 2002, Eindhoven University of Technology has been investigating fully contactless xy-positioning systems. These magnetically levitated planar actuators consist of a single carrier with permanent magnets that is levitated above an array of coils and can move fast and accurately over long distances in the xy-plane. Because the magnets are moving, there are no cables or cooling hoses connected to the moving part. Nevertheless, data and energy can still be transferred, using contactless links. This high-precision ‘flying carpet’ was one of the subjects in the lecture programme at the Precision Fair 2008.

Order of frictions and stiffnesses…

For lumped systems consisting of different frictions and stiffnesses, there has been confusion in literature about hysteresis curves and virtual play for many decades.
