Title:
ADJUSTABLE MAGNETIC BUOYANCY GRAVITY COMPENSATOR
Document Type and Number:
WIPO Patent Application WO/2016/134652
Kind Code:
A1
Abstract:
A gravity compensator, comprising a stator (1), a rotor (2), a base (4) and an adjustment mechanism (6), wherein the stator (1) is arranged on the base (4), and the rotor (2) is suspended above the stator (1). The stator (1) comprises a central column magnet (11), the central column magnet (11) being fixed to the base (4) through the adjustment mechanism (6) and enclosed by at least two tile-type magnets (111). A first end of the adjustment mechanism (6) is fixed to the base (4), a second end thereof is fixedly connected to the at least two tile-type magnets (111), and the adjustment mechanism (6) is used for driving the at least two tile-shaped magnets (111) to synchronously move about the central axis of the central column magnet (11) in a radial direction, thereby changing a magnetic path between the central column magnet (11) and the rotor (2), and further adjusting the magnetic buoyancy between the stator (1) and the rotor (2).
