Magnetic levitation turntable with fifteen degrees of freedom and applied to semi-physical simulation platform

Abstract

The invention discloses an ultra-stable and ultra-static rotary table with fifteen degrees of freedom and supported by an active magnetic suspension bearing. Driving mechanisms (10 and 11) are symmetrically mounted on the outer circular surface of a base (4). Driving mechanisms (12 and 13) are symmetrically mounted on the outer circular surface of the driving ring (14). 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), 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), 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 and 11) to rotate clockwise and anticlockwise. Thirdly, the driving mechanisms (12 and 13) drive the driving ring (14) to move, so that the radial and axial magnetic bearing integrated rotor assembly (2) rotates clockwise and anticlockwise, and complete suspension rotation is realized.

Description

Technical field[0001]The present invention relates to a multi-freedom turntable in the ship's reduction in the resilial, and more particularly, it is a super-femal ultrastiotropier capable of achieving a proactive magnetic levitation bearing support for fifteen degree-freedom. The turret is applied to the ship's reduction yarn. The semi-real simulation platform.Background technique[0002]In recent years, with the advancement of magnetic levitation technology, the high-speed magnetic levitation motor has rapidly developed, which has the advantages of high speed, high power density, small volume, fast response and direct drive load, widely used in high-speed magnetic suspension blowers, magnetic suspension ultra-high vacuum molecules High speed rotating equipment such as pump, magnetic suspension storage flywheel and magnetic housing. The load carrying capacity of the magnetic bearing is determined by design, and is limited by the size, if the actual load exceeds this carrying capacity...
