Single-edge magnetic levitation rotating device adopting double-coil rotating part

Abstract

The invention discloses a single-edge magnetic levitation rotating device adopting a double-coil rotating part. The device is divided into upward levitation and downward levitation types. The downward levitation type is characterized in that: an electromagnet which provides a pull-up magnetic levitation force and has a downward opening and the double-coil rotating part which provides a rotating force are arranged in a box body; a magnetic levitation permanent magnet and a rotation magnetic piece are arranged on the upper part of a magnetic levitation rotating body; the magnetic levitation rotating body carries out magnetic levitation and two-way automatic rotation below the box body; and a space below the magnetic levitation rotating body can be completely emptied out. The upward levitation type is characterized in that: a turbinate magnetic levitation permanent magnet and the rotation magnetic piece are arranged on the lower part of the magnetic levitation rotating body; a hollow magnetic ring which provides a lifting force is arranged in the box body below the magnetic levitation rotating body; the electromagnet which provides a downdraft magnetic levitation force and has an upward opening, a limiting coil for centre positioning and double coils are arranged in the ring; by a centripetal electromagnetic component force which is provided by the limiting coil, the slipping, overturning and fly-off of the magnetic levitation rotating body during levitation by the lifting force below the magnetic levitation rotating body can be avoided, so the magnetic levitation rotating body can stably carry out magnetic levitation and two-way random automatic rotation above the box body, and the space above the magnetic levitation rotating body can be completely emptied out. The device is elegant in appearance and has a better magnetic levitation visual effect.

[0002] The magnetic levitation device that the magnetic levitation body automatically rotates at the same time as the magnetic levitation, such as patents: ZL99252312.5 and ZL00115354.4, and ZL03141646.2, uses the upper and lower parts of the frame box, and the upper and lower boxes are equipped with elements. Devices, between the upper and lower boxes, there is a hollow conjoined body, which is pierced with wires connecting the upper and lower components, and the upper and lower parts of the maglev body are equipped with permanent magnets, and the maglev body is magnetically floated between the upper and lower boxes; therefore, the maglev It is impossible to completely vacate the top or bottom of the body, which has limitations on the overall shape; if you want: the bottom of the maglev body is completely vacated and rotates automatically, patent: 20041004847.6, using: discrete rotation system, structure and adjustment Complicated, it is difficult to achieve two-way automatic rotation; especially to completely vacate the upper part, it is necessary to use the magnetic floating body to be pushed upward by the magnetic force repelled by the same magnetic force below, which will cause the magnetic floating body to translate, roll over or fly away. Measures. The known method in the past is to set a gyro that can be manually rotated at one time directly above the hollow magnetic ring, and use the magnetic field at the center of the magnetic ring to reverse the conical shape of the lower part of the top gyro. The lower magnetic surface of the same magnetism of the permanent magnet produces the magnetic force of mutual repulsion, supports it up, and utilizes the effect of the "central axis centering" of the inertia of fast flying to make it magnetically levitate in the air, but the energy consumption If it turns slowly, it will fall down; in order to make the magnetic levitation body permanent and stable, it needs power supply, sensor, and electromagnetic control device, such as patents 200620008726.0 and 200620007698.0, all use: magnetic ring, multiple electromagnets, circuits, but the structure And debugging is complicated, and 200620019190.2, though simplified, but above-mentioned three patents all only state that maglev body can only be done the horizontal " free " rotation of vertical central axis (this and " automatic " rotation are two different things), thereby, all do not have Explain that it has the function and characteristics of bidirectional random "automatic rotation" that can adapt to different maglevs, and does not provide relevant technical solutions and specific implementation methods. In the above published patents, it has been stated that the control they adopt Circuits are also well-known control methods and circuits that have been used in related professions for a long time. Common magnetic levitation devices, such as: patents: ZL99252312.5 and ZL00115354.4 and ZL03141646.2, use the upper and lower parts of the frame box , the upper and lower boxes are equipped with components, between the upper and lower boxes, there is a hollow connecting body, which is threaded with wires connecting the upper and lower components, and the upper and lower sides of the magnetic floating body are equipped with permanent magnets, and the magnetic floating body is magnetically floating on the upper and lower sides. Between the cabinets; therefore, it is impossible to completely vacate the top or bottom of the maglev, which has limitations on the overall shape; if you want to: completely vacate the top or bottom, you need to consider the structure separately, especially: vacate the top , it is necessary to use the magnetic floating body to be pushed upward by the magnetic force repelled by the same magnetic force below, which will cause the magnetic floating body to roll over or fly away, and special measures need to be taken.
