Problems solved by technology

The problem in the traditional electromagnetic levitation system is that when the size or weight of the suspended object changes, the system must replace the base magnet to offset the gravity of the suspended object with a suitable magnetic repulsion force, which makes the electromagnetic levitation device Adaptability is very limited

Abstract

The invention discloses an adjustable magnetic levitation device, which includes a base, and is characterized in that a coil assembly is arranged on the base, the coil assembly is fixedly connected with the base, and the coil assembly is sheathed with magnet, the magnet is fixedly connected to the base, the coil assembly is provided with a Hall sensor, the Hall sensor is fixedly connected to the coil assembly, an adjustment assembly is provided under the base, and the The adjusting component is movably connected with the base. In the present invention, the base is used to fix other components, the adjustment component adjusts the relative position of the coil component and the magnet, and the Hall sensor detects the lateral displacement direction of the suspended object in real time, so that the control circuit system can feedback control the four coils The magnitude and direction of the current are used to suppress the lateral displacement of the suspended matter, so that the suspended matter can be suspended stably.

Description

technical field [0001] The invention relates to the field of electrical appliances, and more specifically, the invention relates to an adjustable magnetic levitation device. Background technique [0002] At present, the magnetic levitation technology is to use the magnetic force generated by the magnetic field to overcome the gravity, so that the object is suspended in the air without contact. Due to the excellent characteristics of low noise, no pollution, no mechanical contact, etc., it can eliminate the resistance caused by friction and prolong the service life of the equipment. Therefore, magnetic levitation has broad application prospects in various aspects such as transportation, metallurgy, machinery and electrical appliances. The commonly used magnetic levitation technology can be roughly divided into two types: electric levitation and electromagnetic levitation, and can be divided into attractive levitation and repulsive levitation in terms of the way of force. Ele...
