Abstract： |
This invention relates to a magnetic-suspension plane working platform moving in large sphere including a base platform and a mobile one, in which, the mobile platform is composed of a flat stand and a mobile electromagnetic structure set at the bottom of the flat stand, a plane magnet array is set at the top of the base platform, the mobile electromagnetic structure is composed more than three armatures, each of which includes an armature iron core, phase X winding and phase Y winding mutually overlapped on the vertical direction of the bottom of the unit, and any effective side of the phase X is vertical to any effective side of phase Y, so the mobile platform can move on the base platform far more larger than the moble platform plane. |
