Embodiment Construction

[0036] The non-track contact maglev trolley includes working power supply, console, power steering gear, demonstration platform, maglev track, maglev trolley, and several parts are as follows:

[0037] Working power supply: use 220V50HZ AC, equipped with potentiometer and thyristor voltage regulator (adjusting the voltage output to the primary of the transformer to change the secondary voltage), transformer step-down, diode bridge rectification, capacitor filter and other components. Output 5v to 25v adjustable DC voltage (with voltmeter display), output current 8A.

[0038] Power supply mode of power supply contactor: In the center of the demonstrator platform, a copper clad plate with a diameter of 8cm is used to set the inner and outer circular surfaces, see figure 1 , set the outer surface A to be divided into concentric circles equal to twice as many permanent magnets as the magnetic levitation track of the magnetic levitation car, (take the interval to connect one piece)...

Abstract

The invention discloses a track contact-less magnetic levitation trolley demonstrator which comprises a working power supply, a power supply steering device, a console, a demonstration platform, a magnetic levitation track and a magnetic levitation trolley, wherein the demonstration platform comprises a support, a rubber-plastic plate platform, a power supply contactor and a fixing disc; the fixing disc is provided with elastic pieces; the outer circle of the power supply contactor is connected with an anode of the power supply, an inner circle is connected with a base of a composite triode of the console, and the outer circle and the inner circle are in frictional contact with the elastic pieces of the fixing disc; the two elastic pieces of the fixing disc are in fixed short circuit; the rubber-plastic plate platform is provided with a central spindle; the magnetic levitation track comprises a round track; multiple holes are uniformly formed in the round track, and upward permanent magnets with like polarity are arranged in the holes; two coils are arranged at the bottom in the trolley body; the distance between the two coils is equal to the distance between the two magnets of the magnetic levitation track; and the power supply steering device is connected with the coils through the spindle and a connecting rod. The magnetic levitation trolley disclosed by the invention can run on the round track without contact, and has the advantages of high levitation and fast and stable running.

Description

technical field [0001] The invention relates to a magnetic levitation car demonstrator, in particular to a trackless contact magnetic levitation car demonstrator. Background technique [0002] Maglev technology originated in Germany. As early as 1922, German engineer Hermann Kemper proposed the principle of electromagnetic levitation, and applied for a patent for maglev trains in 1934. After the 1970s, with the continuous strengthening of the economic strength of the world's industrialized countries, in order to improve the transportation capacity to meet the needs of their economic development, developed countries such as Germany, Japan, the United States, Canada, France, and the United Kingdom have successively begun to plan for the development of maglev transportation systems. . [0003] The idea of ​​using magnetic force to keep objects in a non-contact levitation state is an ancient dream of human beings, but it is not easy to realize. Because the magnetic levitatio...
