Lifting type magnetic suspension device

Abstract

The invention discloses a lifting type magnetic levitation device, and belongs to the technical field of magnetic levitation control. The device comprises a stator, a floater, a support plate, a lifting mechanism, a centering mechanism, a rack and a system panel, The stator arranged on the support plate is an annular magnet comprising more than three magnetic field change intervals, the more thanthree magnetic field change intervals are uniformly distributed on the annular magnet, and the more than three magnetic field change intervals enable a magnetic field of the stator to form an annularwavy magnetic field with local weakening or enhancement. The floater arranged on the system panel comprises a central magnet and positioning magnets which are the same as the magnetic field change intervals in number and correspond to the magnetic field change intervals in position. The central magnet provides magnetic repulsion to lift the floater, and the positioning magnets are positioned between two adjacent magnetic field gaps of the stator by means of magnetic attraction to overcome horizontal rotation or oscillation of the floater. The controller controls the centering mechanism and thelifting mechanism to achieve the automatic resetting and jacking of the falling floater and the dynamic suspension of the floater.

Description

technical field [0001] The invention belongs to the technical field of magnetic levitation control, and in particular relates to a lifting type magnetic levitation device. Background technique [0002] At present, open maglev products are mainly concentrated in the fields of indoor decoration, product display and popular science education. Generally speaking, this type of magnetic levitation technology needs to be realized through the permanent magnet part of the stator and the float and the electromagnetic control part located in the stator, and can be divided into two types: lifting type and pull-up type. [0003] The lifting type magnetic levitation system has an open space above the float, so its teaching and demonstration effect is generally better than that of the pull-up type. The lifting system needs to adjust the magnetic field in real time through the circuit in the base, so that the float can be dynamically suspended on the lifting plane. This requires two-dimen...
