Embodiment Construction

[0015] The present invention will be further described below in conjunction with accompanying drawing.

[0016] see figure 1 (a is a perspective view, b is a side view), it can be seen from the figure that the present invention includes a fixing device 1 and a suspension part 2 .

[0017] Fixture 1 ( figure 2 ) base is a fixed platform 3, the fixed platform 3 is used as a base for installing the fixing device 1, and a cylindrical skeleton 9 is fixed on it ( Figure 4 ), the skeleton 9 is wound with solenoid coils 5, and each solenoid coil 5 is provided with a permanent magnet 4, and all the solenoid coils 5 are arranged in an array to form a mixed array of permanent magnets and solenoid coils .

[0018] The lower surface of the suspension part 2 is parallel to the upper surface of the solenoid coil 5 of the fixing device 1 . The suspension part 2 structure see image 3 , the suspension part 2 includes a suspension platform 6, a permanent magnet array attached to the lowe...

Abstract

The invention discloses a repelling magnetic suspension system, comprising a fixed device 1 and a suspension part 2; the fixed device 1 comprises a fixed platform 3 and an array of solenoid coil 5 arranged on the fixed platform 3; the solenoid coil 5 is internally provided with permanent magnets with the same direction of magnetization; the suspension part 2 comprises a suspension platform 6 and a permanent magnet array adhered to the lower surface of the suspension platform 6; the permanent magnet array adhered to the lower surface of the suspension platform 6 is composed of permanent magnet arrays 7 and permanent magnet arrays 8 which are opposite in directions of magnetization; the permanent magnet arrays 7 are arranged in the right middle of the suspension platform 6 and are distributed annularly; the permanent magnet arrays 8 are arranged at four corners of the suspension platform 6 and are distributed foursquare; and a central position on the upper surface of the suspension platform 6 is provided with an angle transducer 10 which is used for detecting the horizontal angle of inclination of the suspension platform 6. The repelling magnetic suspension system has the characteristics of simple structure, good stability, high positioning accuracy, zero friction and the like.

Description

technical field [0001] The invention relates to a magnetic levitation system, in particular to a repulsive magnetic levitation system capable of realizing stable levitation. technical background [0002] Magnetic levitation technology organically combines high and new technologies such as power electronics technology, automatic control technology, sensor technology, and detection technology. It uses electromagnetic force to levitate objects without mechanical contact, so as to meet the high-speed and precise direction of production technology and technology. development needs. Due to the advantages of no friction, no wear, no lubrication, long life, low power consumption, and no noise, the magnetic levitation support has attracted more and more attention. [0003] According to the characteristics of magnets that "opposites attract and same sex repel", the magnetic levitation system is divided into two types: attracting and repelling. Due to the characteristics of the at...
