Abstract

The invention relates to a main control body maglev device with single degree-of-freedom (DOF) movement, and the device has the structural characteristics that the lower end of a main body support is fixedly arranged on a base; the top of the main body support is provided with a permanent magnet; a main control body is arranged in the main body support right below the permanent magnet; and in the main control body, the outer shell of the main control body is of a three-dimensional symmetric structure. The lower part of an iron core is arranged in the outer shell of the main control body, and the upper end of the iron core is provided with a plastic slot; a Hall sensor is horizontally connected onto the upper surface of the plastic slot; an excitation coil is wound on a part of the iron core which is arranged in the outer shell of the main control body; a multi-stage feedback circuit is connected between the excitation coil and the Hall sensor; a control circuit is arranged below the outer shell of the main control body; and a power supply is arranged below the control circuit; the control circuit and a wireless controller are wirelessly linked. According to the main control body maglev device with single DOF movement, one-dimensional movement is realized in a levitation direction through the control modules (the control circuit and a wireless receiving module) of the main control body, and the device has the advantages of stability and reliability in movement control and convenience in maintenance.

Description

technical field [0001] The invention relates to a single-degree-of-freedom movement main control body magnetic levitation device. Background technique [0002] The basic principles of magnetic levitation are: (1) magnetic levitation of diamagnetic material; (2) superconducting magnetic levitation; (3) spin magnetic levitation (maglev gyro); (4) servo electromagnetic levitation. Superconductors are completely anti-magnetic levitation, the same as anti-magnetic levitation. The levitation is very stable and has good magnetic recovery, but this also limits the movement of the levitation body in the levitation direction. The magnetic field of the magnetic levitation gyroscope must meet the "well" shape distribution, and the movement in the levitation direction is limited by its fragile stability. At present, the application is more servo electromagnetic levitation. All kinds of magnetic levitation devices on the market are mostly passive body suspension, which is characteri...
