Sight-stabilizing active magnetic suspension rotary table with 10 degrees of freedom

Abstract

The invention discloses a sight-stabilizing active magnetic suspension rotary table with 10 degrees of freedom. Driving mechanisms (10 and 11) are symmetrically mounted on the outer circular surface of a base (4). A plurality of radial and axial magnetic bearing integrated rotor assemblies (2) with the same structure are arranged on the circumference of the disc body (3), four radial and axial magnetic bearing integrated stator assemblies (6, 7, 8 and 9) are symmetrically distributed on the outer circumference of the magnetic suspension rotating platform (1), and a single-shaft turntable driving mechanism (5) is arranged in the center of the magnetic suspension rotating platform (1). Under the power-on condition, the radial and axial magnetic bearing integrated stator assemblies (6, 7, 8 and 9) are powered on to suspend the radial and axial magnetic bearing integrated rotor assembly (2), and on one hand, the radial and axial magnetic bearing integrated rotor assembly (2) is driven by the single-shaft turntable driving mechanism (5) to rotate; and on the other hand, the radial and axial magnetic bearing integrated rotor assembly (2) is driven by the driving mechanisms (10, 11) to realize complete suspension motion in clockwise, anticlockwise and vertical directions. An active vibration suppression function of the magnetic suspension bearing is adopted, mechanical isolation is achieved for micro-vibration of the sight-stabilizing active magnetic suspension rotary table, and the purpose of ultra-stability and ultra-quietness is achieved.

Description

technical field [0001] The invention relates to a turntable for a large-scale visual measurement camera, more particularly, refers to a stable aiming active magnetic suspension supported by an active magnetic suspension bearing that can complete clockwise movement, counterclockwise movement, and vertical movement in a magnetic suspension state turntable. Background technique [0002] In recent years, with the advancement of magnetic levitation technology, high-speed magnetic levitation motors have developed rapidly. They have the advantages of high speed, high power density, small size, fast response, and can directly drive loads. They are widely used in high-speed magnetic levitation blowers, magnetic levitation ultra-high vacuum molecules, etc. High-speed rotating equipment such as pumps, magnetic levitation energy storage flywheels and magnetic levitation torque gyroscopes. The bearing capacity of the magnetic bearing is determined by design and is limited by its size. I...
