Description

Superconducting permanent-magnet motor

The invention belongs to mechanical field:

Rationale superconductor perfect diamganetism of the present invention, with frozen magnetic flux effect in the superconducting pipe, in on October 15th, 1992 in Experimental Center of Low-Temperature Technology, Academia Sinica, by He Yeye, Li Bing, Ceng Xinglin engineer is with superconducting magnet solenoid external diameter Φ 80MM, internal diameter Φ 54MM, long 130MM and metal niobium superconducting pipe, external diameter Φ 17MM, internal diameter Φ 15MM, long 200MM, a pure iron Φ 15MM is equipped with in niobium pipe lower end, long 40MM, put into niobium infratubal port 20MM, shown in (as Fig. 2), the metal niobium pipe is put into superconductor solenoid 87MM, niobium pipe upper end spills superconductor solenoid 130MM, superconductor solenoid and metal niobium superconducting pipe are put into the 4.2K liquid helium, the superconducting solenoid magnet rises the field to 1.9T, and demagnetizing field extremely, the hall probe measurement shows that frozen magnetic flux distributes as follows in the niobium pipe:

20MM、0.85T、30MM、0.229T、40MM、0.200T、

50MM、0.183T、60MM、0.180T、70MM、0.164T、

80MM、0.177T、90MM、0.051T、100MM、0.014T、

Mechanical test results, dynamometry probe Φ 12MM, length 12.3MM, put into the superconducting pipe upper end and inhale to the lower end attraction at each point, 80MM, 60.49 gram, 50MM, 170.61 gram, 30MM, 104.03 gram, two probe spacing 12MM, survey each point attraction 80MM, 116.6 gram, 50MM, 163 grams, 30MM, 150 grams, the Mechanical test results conclusion is as follows, type I superconductor is current-carrying consumed energy not in superconducting state, under meissner state, total magnetic flux constant (frozen magnetic flux) superconducting pipe in the superconducting pipe on any cross sections is long more, homogeneity range is long more in the pipe, and work done equals power and takes advantage of distance, therefore, superconducting pipe is long more, and the probe iron block is inhaled big more to the lower end work done from the superconducting pipe upper end, shown in (as Fig. 2), magnet or pure iron (2) are inhaled to magnet (3), magnet or pure iron (2) (3) are drawn onto together, and aft hook (7) (8) plugs together mutually, with external force magnet or pure iron (2) (3) are pulled out superconducting pipe together, experiment draws as drawing a conclusion, the negative page or leaf of 0412 test report, when magnet or pure iron (2) (3) when pull out the superconducting pipe rear end, and gravitation reduces gradually, after pure iron or magnet (2) (3) were pulled out the niobium pipe, attraction decayed with square distance.

Niobium pipe superconducting characteristic test report NO:0124 test report hands over filing office of Patent Office to file with application for patent simultaneously.

The 2nd test on December 19th, 1992 superconducting pipe characteristic, with niobium superconducting pipe external diameter 22MM, internal diameter 19MM, length 610MM, niobium infratubal port have a diameter of phi 19MM, and the iron block of long 15MM inserts 15MM in the niobium pipe rear port.The niobium infratubal port is 0MM, and upper port is 585MM, measuring magnetic field 0MM, 0.1551T, 25MM, 0.1363T, 50MM, 0.1353T, 100MM, 0.1382T, 200MM, 0.1434T, 300MM, 0.1451T, 400MM, 0.1412T, 500MM, 0.1397T, 550MM, 0.1307T, 585MM, 0.0183T measuring probe inhale from niobium pipe upper end to niobium pipe lower end in the each point attraction, iron block probe diameter Φ 10.9MM, long 11.2MM, survey each point attraction 0MM, 1 gram, 25MM, 1 gram, 50MM, 36 grams, 100MM, 4.3 gram, 200MM, 0.4 gram, 300MM, 5.5 grams, 400MM, 7.6 gram, 500MM ,-1.3 grams, 550MM, 34.6 grams, 585MM, 0.4 gram, the report of NO:0129 number test niobium pipe characteristic, the 4th, record through international online retrieval, since 1963, containing China does not have the patent (Britain Derwent patent information system) of utilizing superconducting pipe and magnet or iron core interaction work done in 31 interior countries.Since 1979, not seeing in the world has frozen magnetic flux and magnet or the interactional paper of iron core (German STN international literature information network) in the research superconducting pipe.This material is responsible for retrieval by He Yeye.The NO:0129 test report is filed with the patent application document application, the present invention makes superconducting pipe freeze the gradient magnetic flux with half magnetization superconducting pipe of superconductor solenoid magnet, and niobium superconducting pipe A-B end does not magnetize, the C-D end does not magnetize, and makes niobium pipe B-C end institute frozen magnetic flux gradient put at the B-C point constant.Shown in (as Fig. 2).Niobium pipe A-B, C-D length is greater than several times of niobium pipe diameters, and one section port of niobium infratubal port C point is thinner than niobium mouth of pipe footpath, and the niobium pipe proves that by experiment where just where the niobium pipe magnetizes magnetic field, and not magnetized place does not have frozen magnetic flux.

It is earlier superconductor solenoid gradient magnet to be put into the 4.2K liquid helium that the superconducting pipe method is magnetized in the present invention, superconducting pipe is put into shown in the little liquid pool of Dewar bottle (as Fig. 2) earlier with the little liquid pool of superconducting pipe (1) Dewar bottle (6), the elder generation's little liquid pool of tapping helium (6) E-C point makes niobium pipe C-D point enter the 4.2K superconducting state, solenoid (4) send magnetic field, and magnetic field can not be greater than niobium pipe H in the middle of solenoid (4) in magnetic field _C1Make niobium pipe (1) B-C point magnetization gradient frozen magnetic flux, make niobium pipe (1) B point magnetic field minimum, C point magnetic field maximum, if through what experimental results show that metal niobium pipe frozen magnetic flux freezes is the gradient magnetic flux, magnet or pure iron (2) can be inhaled to magnetic field C end of heap of stone by little B end from magnetic field, at this moment the strong magnetic of ferro-niobium boron also can be inhaled from the B end and hold to niobium pipe C, attraction has about several kilograms, superconducting pipe (1) B-C point also can directly be made tapering, the B spot diameter is big, and the C spot diameter is little, can oneself go into the gradient frozen magnetic flux in superconducting pipe (1).

Structure of the present invention is shown in figure (1).

Superconducting pipe (1) (2) can cross film with metal niobium pipe or vacuum and make, with solenoid gradient magnet magnetization superconducting pipe B-C point, superconducting pipe (1) (2) is gone into the gradient frozen magnetic flux, superconducting pipe (1) (2) A-B, the C-D end does not magnetize, it is superconducting state, A-B, C-D end superconducting pipe is a shape, if have only pure iron superconducting pipe (1) (2) A-B without magnet on the chain, C-D end diameter can with superconducting pipe (1) (2) B, the C spot diameter equates useful shape, and chain is also can be the strong magnetic of 3-4 kilogauss neodymium iron boron (3) (4) (5) (6) (7) (8) (9) (10) (11) etc. by magnet or pure iron.Form with no magnetic metallic bond batten (12), chain is supported by chain wheel (13) (14), chain wheel is fixing by axle (15) (16) and casing (17), guiding no magnetic metal sleeve (18) (19) niobium superconducting pipe (1) B end diameter is housed in the superconducting pipe (1) (2) holds diameter less than C, niobium superconducting pipe (2) B end diameter is held diameter greater than C, superconducting pipe (1) B end magnetic field is big, C end magnetic field is little, big B end magnetic field, superconducting pipe (2) C end magnetic field is little, energy is externally exported in axle (15) (16), and with the outer magnetic coupler of machine, clutch, speed changer connects.

Motion principle

Magnet or pure iron, also can be that the strong magnetic of neodymium iron boron (4) (5) (6) holds work done greater than the resistance of niobium pipe B end magnetic field to magnet or pure iron (3) from the suction of C end to niobium pipe (1) B, magnet or pure iron also can be that neodymium iron boron (8) (9) (10) is inhaled to the work done of C point greater than the resistance of superconducting pipe (2) C point to magnet or pure iron (7) from the B point.Chain drives chain wheel (15) (16) and rotates, and the present invention can be used as the power source of generating and all processing equipments.
