Lower support type magnetic levitation device with integrated rotating system

Abstract

The invention provides a lower support type magnetic levitation device with an integrated rotating system, comprising a lower support type magnetic levitation permanent magnet arranged at the lower part of a magnetic levitation rotating body, a rotating magnetic piece, a lower support force electromagnetic ring arranged in a lower box body, a centering electromagnet, an integrated rotating component and a circuit board; according to a lower support type magnetic levitation system provided by the invention, when an upwards jacking adjustable magnetic push of the lower support force electromagnetic ring arranged at the lower part of the magnetic levitation rotating body is adjusted and controlled to be equal to the weight of the magnetic levitation rotating body after subtracting a controllable lower absorption electromagnetic force of the centering electromagnet, the magnetic levitation rotating body magnetically levitates, the magnetic levitation is stable, and the 'charging levitation' is easier to carry out due to a plurality of means for avoiding the slippage and the turnover of the magnetic levitation rotating body, so that the lower support type magnetic levitation device is suitable for the two-way automatic rotation of various magnetic levitation rotating bodies; and the magnetic levitation rotating body magnetically levitates above the lower box body and bi-directionally and automatically rotate, and the upper part of the magnetic levitation rotating body can be completely emptied, so that the device is novel and very good in visual effect, and the device is simple in structure, convenient to adjust and control, low in cost, and easy to produce and market.

Description

[0001] Technical field: magnetic levitation, magnetic levitation device technical background: [0002] The common magnetic levitation device is "hanging type", and the electromagnet in the upper box applies an electromagnetic force of upward suction to the upper part of the magnetic floating body below to balance the weight of the magnetic floating body; It is necessary to send upward repulsive magnetic force to the lower part of the maglev body in the lower box to balance the weight of the maglev body. The electromagnets are all in the lower box. The lower part of the body "slips" outward and the whole part overturns, which is a problem; patent: 200610065336.1 uses the middle part of the lower box to set four electromagnet groups with openings upward, plus four displacement sensors, and four groups of linkages The "slip" control circuit is provided with a large permanent magnetic ring on the periphery of the electromagnet group to provide upward magnetic repulsion, but the ma...

[0002] The common magnetic levitation device is "hanging type", and the electromagnet in the upper box applies an electromagnetic force of upward suction to the upper part of the magnetic floating body below to balance the weight of the magnetic floating body; It is necessary to send upward repulsive magnetic force to the lower part of the maglev body in the lower box to balance the weight of the maglev body. The electromagnets are all in the lower box. The lower part of the body "slips" outward and the whole part overturns, which is a problem; patent: 200610065336.1 uses the middle part of the lower box to set four electromagnet groups with openings upward, plus four displacement sensors, and four groups of linkages The "slip" control circuit is provided with a large permanent magnetic ring on the periphery of the electromagnet group to provide upward magnetic repulsion, but the magnetic ring is large and heavy, and the magnetic repulsion is fixed and not adjustable. The magnetic ring made of "iron carbon oxygen" material will "demagnetize" after a long time, and the magnetism will be unstable with the change of temperature. In addition, the circuit of the electromagnet group is too complicated. Using multi-stage high-magnification DC amplification will inevitably cause Some "temperature drift", so the overall is very complicated, the cost is too high, the regulation is very difficult, and the stability is poor; in addition, the patent: 200610666175.8 uses two electromagnets and two additional limit permanent magnets, although simplified , but cause other difficulties in regulation and control, and the system is more unstable; and the above patents do not have the structure and the design of the rotating circuit that can make various types of maglevs stably rotate automatically, so they are not ideal and need to be used separately. thoroughly solve it
