The invention discloses an ultra-stable and ultra-static single-axis turntable supported by an active magnetic suspension bearing. A plurality of radial and axial magnetic bearing integrated rotor assemblies (2) with the same structure are arranged on the circumference of a disc body (3), and rotate in the magnetic suspension. Four radial and axial magnetic bearing integrated stator assemblies (6, 7, 8, 9) are symmetrically distributed on the outer circumference of the platform (1), and a single-axis turntable drive mechanism (5) is arranged in the center of the magnetic suspension rotating platform (1). Under the condition of electrification, the radial and axial magnetic bearing integrated stator assemblies (6, 7, 8, 9) are first electrified to suspend the radial and axial magnetic bearing integrated rotor assembly (2), and then the radial and axial magnetic bearing integrated rotor assembly (2) is suspended by the single-axis turntable drive mechanism (5). The axial magnetic bearing-integrated rotor assembly (2) rotates to realize complete suspension rotation.
Description
technical field [0001] The present invention relates to a turntable suitable for magnetic levitation, more particularly, refers to an ultra-stable and ultra-quiet single-axis turntable capable of realizing five-degree-of-freedom active magnetic levitation bearing support. 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. If the actual load exceeds this bearing capacity, or the support of the magnetic beari...
