On this page, you can see a Magnet Array which is based on contactless planar actuator technology. This array can be used for fully contactless xy-positioning systems. The magnetically levitated planar actuators consist of a single carrier with permanent magnets levitating above an array of coils.
The magnet carrier can move fast and accurately over long distances in the xy-plane. Moreover, there are no cables or cooling hoses connected to the moving part, because the magnets are moving instead of the coils. Nevertheless, data and energy can still be transferred using contactless links.
