Problems solved by technology

However, this way is to use opposite repulsion, that is, the repulsion generated by the specific area above the base with opposite polarity and the suspension module to achieve suspension, the magnetic repulsion that can be provided is still limited; moreover, the magnetic field line density at the suspension module position is still relatively dense. , when the suspension module has a certain horizontal offset and tilt, the generated eddy current loss is still relatively large

Abstract

The invention discloses a magnetic suspension device which comprises a base module, a suspension module and a control module. The base module comprises a first magnet which is magnetized in the radial direction. The suspension module comprises a second magnet which is axially magnetized; the inner side of the first magnet shows a first magnetic polarity, the outer side of the first magnet shows a second magnetic polarity, and the first magnetic polarity is opposite to the second magnetic polarity; the upper surface of the second magnet shows a third magnetic polarity, the lower surface of the second magnet shows a fourth magnetic polarity, and the third magnetic polarity is opposite to the fourth magnetic polarity; the suspension module can suspend above the base module; and the control module is used for keeping the suspension module to suspend stably. The invention has the advantages of strong suspension force, good suspension stability and the like.

Description

Technical field [0001] The present invention relates to the field of magnetic levitation technology, in particular to a magnetic levitation device. Background [0002] The current magnetic levitation device, or the use of the "same-sex repulsion" principle, so that the upper surface of the base and the lower surface of the suspension module polarity are the same, through the principle of homosexual repulsion, to produce magnetic repulsion to balance the weight of the suspension module, so that it levitation; but the suspension performance of this method is limited, the volume distribution of the suspension module is uniform, the weight distribution is uniform, and it can only be equipped with specific objects with regularity such as coins, cup covers, etc.; once there is a small amount of offset, the magnetic induction line through the suspension module will change rapidly, so that it will lose its balance. And because the suspension module is located in the most dense position o...
