大范围移动磁浮平面工作台
摘要：
大范围移动磁浮平面工作台，涉及一种磁浮平面工作台，特别是一种大范围移动磁浮平面工作台，主要应用于制造设备与机器人领域。该工作台包括基台和移动台，所述移动台由平台和设置于平台底部的移动电磁结构组成，在基台顶部设置有平面永磁阵列，移动电磁结构由3个以上电枢单元组成，每个电枢单元包括电枢铁心、X相绕组和Y相绕组，X相绕组和Y相绕组在电枢单元底面的竖直方向上相互重叠，且X相绕组的任一有效边与Y相绕组的任一有效边之间相互垂直。由于所述移动台的移动范围不受移动台尺寸的限制，使得移动台可以在平面尺寸远大于移动台平面尺寸的基台上移动，从而大大增加了移动台的相对行程，实现移动台的大范围平移。
摘要（英）：

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.
