Magnetic suspension demonstration instrument and modeling method thereof

Abstract

The invention provides a magnetic suspension teaching demonstration instrument and a modeling method thereof. The magnetic suspension teaching demonstration instrument comprises an annular permanent magnet, a magnetic floater, a magnetic field detection module, a microprocessor and a driving circuit. A plurality of electromagnetic coils are disposed on an inner ring of the annular permanent magnet, the magnetic floater suspends above the plurality of electromagnetic coils, the magnetic field detection module is used for converting a magnetic field change into a voltage signal, the magnetic field detection module comprises at least three magnetic field sensors, the three magnetic field sensors respectively correspond to the X-axis direction, the Y-axis direction and the Z-axis direction, the microprocessor is used for converting the voltage signal into a current control signal to control the driving circuit, and the driving circuit is used for driving the electromagnetic coils to changean electromagnetic field so as to suspend the magnetic floater.

Description

technical field [0001] The invention relates to a teaching demonstration instrument, in particular to a magnetic levitation demonstration instrument and a modeling method thereof. Background technique [0002] Magnetic levitation technology is a high-tech integrating electromagnetics and electromagnetic induction technology. With the development of electronic technology, control engineering and electromagnetic theory, magnetic levitation technology has made great progress. Although maglev technology has made great progress, the concept of maglev is still too abstract and difficult for school students to understand, which is not conducive to students' mastering and application of maglev knowledge. It is necessary to provide a concrete demonstration instrument to concretize the abstract concept. To enable students to better grasp the characteristics of maglev. Contents of the invention [0003] In order to solve the problem that the concept of magnetic levitation is abstrac...
