Group, p-m rotor includes curve fence row pattern rotor punching.Graphene (Graphene) be stripped out from graphite material, by
The two dimensional crystal of only one layer of atomic thickness of carbon atom composition.Graphene is both most thin material, and most tough material,
Fracture strength is more taller than best steel 200 times, while it has good elasticity again, stretch range can reach own dimensions
20%, it is that current nature is most thin, intensity highest material.If making hammock with one piece of area, 1 square metre of Graphene, this
Heavy sensation of the body amount just can bear one one kilogram of cat less than 1 milligram.Graphene has perfect two dimensional crystal structure, its lattice
It is the hexagon for being surrounded by six carbon atom, thickness is an atomic layer.Bonded by σ between carbon atom, combination is sp2
Hydridization, these σ keys impart the extremely excellent mechanical property of Graphene and structural rigidity.The hardness of Graphene is than best iron and steel
Strong 100 times, or even to also exceed diamond.In Graphene, each carbon atom has the p electronics of a non-bonding, these p electronics
Can move freely in crystal, and movement velocity is up to the 1/300 of the light velocity, this gives the good electric conductivity of Graphene.Stone
Black alkene is the transparent conductive material of a new generation, and in visible region, the transmitance of four layer graphenes is suitable with traditional ito thin film,
In other wave bands, the transmitance of four layer graphenes is significantly larger than ito thin film.Graphene is that known world is most thin, most hard
Nano material, it is almost fully transparent, only absorbs 2.3% light, and heat conductivity is up to 5300W/m K, higher than carbon nanometer
Pipe and diamond, under room temperature, its electron mobility is more than 15000cm2/ V s, but higher than CNT or silicon crystal, and resistance
About 10~6 Ω cm of rate, lower than copper or silver, it is the material of world resistivity minimum.Because its resistivity is extremely low, electron transfer
Speed be exceedingly fast, therefore can be used to develop thinner, conductive speed a new generation's electronic component or transistor faster.The going out of Graphene
Scientific circles have evoked huge great waves now.It has been found that Graphene has unusual electric conductivity, tens of beyond iron and steel
Intensity again and fabulous light transmission, its appearance is expected to cause one to take turns revolution in hyundai electronicses sciemtifec and technical sphere.In Graphene,
Electronics extremely efficiently can be migrated, and traditional quasiconductor and conductor, such as silicon and copper are far from, Graphene show must well.By
In the collision of electronics and atom, the form of traditional quasiconductor and conductor heat releases some energy, general electricity in 2013
Brain chip wastes 72%~81% electric energy by this way, and Graphene is then different, and its electron energy will not be depleted, this
It is made to be provided with extraordinary good characteristic.
More interestingly the physical property of it that many " extreme " properties.Because only that one layer of atom, electronics
Motion is limited in a plane, and Graphene also has brand-new electrical properties.Graphene is that electric conductivity is best in the world
Material, electronics movement velocity wherein has reached the 1/300 of the light velocity, the motion speed considerably beyond electronics in general conductor
Degree.Centesimal Graphene is mixed in plastics, can just be made plastics possess good electric conductivity, be added millesimal graphite
Alkene, can make the heat resistanceheat resistant performance of plastics improve 30 degrees Celsius.The stator winding of existing motor be mostly by enamel covered wire coiling and
Become, if penetrating into a certain proportion of Graphene in enamel covered wire will greatly improve electric conductivity and the temperature tolerance of enamel covered wire, will
Make copper cash itself electrical loss be preferably minimized even without, have the efficiency of motor and significantly improve, the volume of motor is significantly
Reduce, particularly heavy-duty motor is meant a great, this energy-saving and emission-reduction consumption reduction to country's concern at present will have revolutionary meaning
Justice.Therefore, the stator winding of this programme absorbs the good characteristic of grapheme material, i.e. graphene composite material stator winding bag
Enamel covered wire is included, enamel covered wire is contained within grapheme material.

Effect inhibits starting current, increases starting torque so that with the raising of motor speed, rotor current and torque while corresponding
Adjustment, after rotor enters working speed, rotor impedance is obviously reduced, and rotor has been issued to ideal in nominal operation rotating speed
Performance indications.At the same time, oval profile it also avoid processing, the assembly difficulty that angular structures are brought, and reduces and turns
Sub- teeth portion eddy-current loss, increases the kelvin effect of rotor, and motor torque is more smoothed, and reduces vibration and the noise of motor,
Make the close distribution of motor rotor teeth portion magnetic more reasonable, improve electric efficiency.Further, in order to improve structure and the property of punching
Can, this programme is circumferentially with 36 oval line embedding grooves of equidistant arrangement in the ring body of circular punching along the outer ring of ring body,
Opening groove is provided between oval line embedding groove and outer ring.Opening groove is released can the stress at notch, will not make punching
Piece is deformed, so as to solve the problems, such as the amount of unbalance for producing as rotor punching deforms and some additional losses,
Certain thermolysis is played to the cast copper in line embedding groove or cast aluminium, and improves rigging error tolerance.Likewise it is preferred that 36
The individual line embedding groove being circumferentially equally spaced effectively improves the distribution situation of cast copper or cast aluminium, makes motor operation more stable, effect
Rate is higher.In the above-mentioned cast copper for referring to or cast aluminium can also graphene-doped material improving the performance of rotor.
The rotor punching of this programme also has other adaptation contents, specifically, in order that the punching for laminating is in week
Alignment, is provided with punching positioning slotted hole on four beam arms of pedestal beam upwards, and adjacent rotor punching is fixed by punching
