Abstract

The invention provides a magnetic levitation driving device and method, and belongs to the technical field of magnetic levitation driving. The device comprises a driven module, a rail and a power supply, the rail is composed of a bottom plate, a left side plate and a right side plate and is U-shaped, a coil is arranged on the bottom plate of the rail, and two rubber magnetic strips are arranged atthe bottom of the bottom plate; the driven module is a square capable of entering the rail, two rectangular strong magnetic sheets are arranged on the upper portion of the square in the moving direction, a round strong magnetic sheet is arranged between the two rectangular strong magnetic sheets, two width compensation sheets and two electric brushes are arranged at the position, close to the four corners, of the bottom of the square, and the two width compensation sheets and the two electric brushes are distributed diagonally. When the device is used, the driven module is enabled to suspendon the track by mutual exclusion of the permanent magnets; and meanwhile, coils are arranged on the rail and are matched with a strong magnetic sheet arranged in the center of the driven module to realize electromagnetic driving. According to the invention, the driving unit can be effectively simplified, and magnetic suspension driving is realized in a simple manner.

Description

technical field [0001] The invention relates to the technical field of magnetic levitation drive, in particular to a magnetic levitation drive device and method. Background technique [0002] Because the magnetic levitation drive needs to use the alternating magnetic field, and the general idea of ​​realizing the alternating magnetic field often needs to use the complex control circuit, which is difficult to realize in the magnetic levitation drive model, so the existing maglev drive device model is very lacking. [0003] At present, the existing magnetic levitation devices on the market, such as magnetic levitation car toys or teaching equipment, are mostly controlled by the interaction between the motor and the program, which improves the viewing effect, but it contains complex programming and driving principles, which makes it difficult to use for the display and display of physical principles. Teaching, and expensive to make. [0004] Patent 201911148600.1 provides a de...
