Principle Structure Of Magnetic Levitation Table Light
In fact, the magnetic levitation table light is a typical mechatronic system. It uses the scientific method of magnetic levitation, that is, the magnetic circuit law and the dynamic principle of the magnetic field to generate magnetic force. It consists of the controller and the actuator. As long as the magnetic field direction and the geometric center of gravity of the upper magnet are protected in a straight line, and the magnetic force at this time is the same as the gravity of the upper magnet, the upper special body can be suspended at a certain point in the air. Touching the globe above with your hand can rotate slightly, and then return to the point.
Levitation magnetism is a fairly complex closed-loop feedback servo system. The LED process light manufacturer pointed out that it must have a sensor and feedback amplification control circuit in addition to the electromagnet as an actuator. There are 4 windings around the electromagnet. Coils of metal rods. Its main principle is to achieve the suspension of metal balls by using the eddy current generated by the high-frequency electromagnetic field on the metal surface.
When a metal sample is placed on a coil passing a high-frequency current, a high-frequency electromagnetic field generates a high-frequency eddy current on the surface of the metal material. effect. In the proper space preparation, the direction of the Lorentz force can be opposite to the direction of gravity. The electromagnetic suspension can be achieved by changing the power of the high-frequency source to make the electromagnetic force equal to gravity. The frequency of alternating current through the coil is generally 104-105Hz. At the same time, the Joule heat generated by the eddy current on the metal can melt the metal, thereby achieving the purpose of melting the metal without a container. At present, in the field of space material research, EML technology has played an important role in the study of crystal growth, solidification nucleation and deep undercooling in microgravity and containerless environments.
