Magnetically Levitated Planar Actuator with Moving Magnets [PDF]

open access: yes2007 IEEE International Electric Machines & Drives Conference, 2007
This paper concerns the design, optimization, and commutation of a six-degree-of-freedom planar actuator with an active magnetic bearing. The planar motor has a stationary coil array and a translator with a Halbach magnet array. During movements in the plane, the set of energized coils changes with the position of the translator.

Ironless magnetically levitated planar actuator [PDF]

open access: yesJournal of Applied Physics, 2008
This paper describes a magnetically levitated planar actuator with moving magnets. This ironless actuator has a stationary coil array above which a translator with a permanent-magnet array is levitated and propelled in the xy plane. During the movements in the xy plane, the set of active coils is switched, as a result of which the stroke in the xy ...
