Patent ID: 8599361

Claim:
A nanometer precision six-DOF magnetic suspension micro-stage, characterized by comprising a cross support ( 9 ) and four 2-DOF actuators each comprising a vertically polarized permanent magnet ( 5 ), a horizontal force coil ( 6 ) and a vertical force coil ( 7 ); wherein, the permanent magnet ( 5 ) is mounted on an end of the cross support ( 9 ), the horizontal force coil ( 6 ) and the vertical force coil ( 7 ) are arranged on one side of and below the permanent magnet ( 5 ) respectively and being spaced apart from the permanent magnet; said cross support ( 9 ) and the four vertically polarized permanent magnets ( 5 ) constitute a mover ( 2 ) of the micro-stage; the horizontal force coil and the vertical force coil are mounted via a coil framework ( 8 ) respectively and constituting a stator ( 1 ) of the micro-stage; and the stator ( 1 ) of the micro-stage is mounted on a base ( 3 ) of the micro-stage.
