Description

The present invention relates to a maglev device.

Generally, items are generally composed of multiple parts that are assembled into one. Such items have a fixed form, the configuration of each part cannot be changed, and the structure type cannot be adjusted arbitrarily or matched with other functional parts. Slightly dull.

Different from the above-mentioned fixed-type objects, the magnetic levitation device uses the magnetic force to suspend one part of the device in the air through the principle of magnetic attraction or mutual repulsion. The conventional maglev device includes a base and a floating body. The base is usually provided with an electromagnet, and the floating body is provided with a permanent magnet. The electromagnet is energized to generate a magnetic field, and the magnetic field of the permanent magnet of the floating body and the magnetic field generated by the electromagnet are mutually repelled and suspended.

These problems are especially problematic if the floating body is It is more pronounced for non-spherical bodies.

Therefore, it is necessary to provide a novel and progressive maglev device to solve the above problems.
