Embodiment
Below in conjunction with embodiment and accompanying drawing, the utility model being described further, it should be appreciated by those skilled in the art that embodiment and accompanying drawing are just in order to understand the utility model better, are not used for making any restriction.
Fig. 1-2 shows a specific embodiment of suspended substance in the utility model magnetic levitation system and corresponding magnetic suspension mechanism.Magnet in suspended substance is formed by stacking by two pieces of cylindrical permanent magnet, and permanent magnet 201 diameter of top is greater than the permanent magnet 202 of below, and this arrangement is very suitable for being arranged in spherical suspending body.Magnetic suspension mechanism comprises center permanent magnet 401, annular permanent magnet 402 and levels electromagnetic control system.Wherein, center permanent magnet 401 is solid uniform cylindrical.When suspended substance is normally suspended in above magnetic suspension mechanism, the lower surface magnetic of permanent magnet 201 and 202 is same and contrary with the upper surface magnetic of annular permanent magnet 402 with the upper surface Magnetic Phase of center permanent magnet 401.Center permanent magnet 401 is coaxially arranged with the central shaft of permanent magnet 201 and 202, thus center permanent magnet 401 can produce larger magnetic repulsion to suspended substance in the Z-axis direction, thus suspended substance can be suspended in desirable predetermined altitude.But under normal conditions, because between two homopolarity magnets, the cunning that can occur each other is scolded, only rely on the magnetic repulsion of center permanent magnet 401 to be difficult to suspended substance to suspend.In the utility model, the periphery of utility model Ren center permanent magnet 401 is also provided with annular permanent magnet 402, the upper surface magnetic of annular permanent magnet 402 is contrary with the lower surface magnetic of permanent magnet 201 and 202, and under the effect of annular permanent magnet 402, suspended substance can not overturn in vertical plane.In the preferred case, the upper surface of permanent magnet 201 is provided with magnetic conduction sheet 203, the lower surface of center permanent magnet 401 and annular permanent magnet 402 is provided with magnetic conduction sheet 403.By the guide effect of magnetic conduction sheet 203 and 403, the magnetic fields between suspended substance and magnetic suspension mechanism can be made more concentrated, thus improve efficiency.
In the above-described embodiments, levels electromagnetic control system preferably includes four electromagnet 411-414 and corresponding four Hall element (magnetic sensor) 422-424, four electromagnet 411-414 distribute in horizontal plane centered by the axis of annular permanent magnet (X and Y-axis), again by symmetrically between two serial or parallel connection become one group and make the end in the same way of same group of electromagnet magnetic is contrary after powered up, when the permanent magnet of the suspended substance above its effect with electromagnet group, a horizontal force can be synthesized on permanent magnet.The horizontal force of synthesis can control the horizontal degree of freedom of suspended substance, and such two groups of orthogonal electromagnet just can two degrees of freedom in level of control face, thus suspended substance is equilibrated at above magnetic suspension pedestal.Concrete control circuit and control principle have been conventionally known to one of skill in the art, such as can see Chinese patent application CN1819436A, at this to introduce its full content see mode.
Fig. 3-4 shows another specific embodiment of suspended substance in the utility model magnetic levitation system and corresponding magnetic suspension mechanism.Be with the embodiment difference shown by Fig. 1-2, center permanent magnet 401 is hollow cylinder, and Hall element is only arranged two (422 and 423), is used for respectively detecting the exciting current in X-axis and Y direction.Wherein Hall element 422 and 423 is arranged in the centre bore of center permanent magnet 401, thus reduces component number and save space.
It will be appreciated by those skilled in the art that above-mentioned execution mode only plays and explain effect of the present utility model, and not should be understood to any restriction that it is made.Such as annular permanent magnet 402 is not limited to single annular permanent magnet, can also be the assembly that the cylindricality set of permanent magnets of more than three of annular spread in level or the cylindricality set of permanent magnets of an annular permanent magnet and annular spread are superimposed in the vertical direction.Electromagnet is also not limited to 4, more than two groups (often organize and at least comprise an electromagnet) can be divided into all be fine with the degree of freedom of two on level of control direction, such as 6 etc., correspondingly, the transducer that can control any number of suspended substance two-dimensional freedom motion in the horizontal direction is all fine.In addition, the arrangement of electromagnet can also have multiple, can be arranged on the inside of annular permanent magnet 402, outside or top as required, or is spaced in a circumferential direction with multiple cylindricality permanent magnets of composition annular permanent magnet 402.In addition, electromagnet is also not limited to the coil of ribbon core, and coreless coil can be adopted equally to be used as electromagnet.
