Embodiment
Below in conjunction with drawings and Examples, content of the present invention is described further:
The operation principle of shaftless motor is that rotor (coin or other discoid soft magnetic materials) is magnetized at alternating magnetic field, magnetic field freezing is in rotor, the frequency of frequency when therefore rotor rotates and the alternating electromagnetic field of stator coil is in full accord, is a kind of new-type synchronous motor.When rotor is used in the situation that permanent magnet and soft magnetic material be used in combination, rotor speed or and the frequency of the alternating electromagnetic field of stator coil in full accord.Shaftless motor only has one group of coil, passes to single-phase alternating current during work, and rotor can directly start and automatically reach synchronous speed and stable rotation from zero-speed.If rotor is only used soft magnetic material, because rotor can, by stator coil field drives, therefore need larger alternating magnetic field condition after must being first magnetized.Rotor is freely beated in stator coil inner space, generally needs the time of 0 to 10 second, gets final product stable rotation; After stable rotation, reduce magnetic field condition and still can realize stable rotation.If rotor adopts the mode of permanent magnet and soft magnetic material combination to make, generally within 3 seconds, just can automatically start and realize stable rotation.
The shaftless motor schematic diagram of the air core coil stator shown in Fig. 1, the air core coil stator of shaftless motor passes to after alternating current, just can drive rotor to rotate continuously, by precession and the Sloped rotating of rotor, just can observe the matter wave of macro object.
Fig. 2 is the shaftless motor schematic diagram of U-shaped soft magnet stator, and rotor forms in arc potential well at electromagnetic field and the gravity of U-shaped soft magnet stator, and arc potential well keeps rotor stability to continue to rotate.
During the stator coil winding of shaftless motor, consider whether use iron core, if use air core coil as stator, so coil necessarily turn to cylindrical, the arc of coil inside like this, just nature provides arc potential well for rotor stability rotation; If use coil and iron core group to be combined into stator, it is rectangle that coil generally turns to cross section, and iron core is just easily selected like this, and arc potential well needs to make in addition the concave surface of arc.
The rotor of shaftless motor, can select coin directly to use; Also surperficial figuratum disk rotor can be made, soft ferromagnetic material can be selected, or the mode of permanent magnet and soft ferromagnetic material combination making.
If desired, can coordinate frequency converter (or variable-frequency transformer), stroboscope etc. to use together.
Matter wave is observed embodiment
When using coin as rotor, the phenomenon that can observe is roughly two kinds of situations: a kind of is the rotation that coin only has vertical axis, and this situation is more fewer.Only have in the situation that vertical axis rotates, two faces of coin can see, two faces overlap.This is visual persistence phenomenon, historical bird enters cage and just by the mankind, is known (a disk, one side draws a bird, another side draws a cage, when disk rotates around diameter (vertical axis), due to the persistence of vision, bird and cage coincide together, as bird has entered into cage, be called bird and enter cage).The second situation is, coin is in the situation that vertical axis rotates, also follow the quick rotation of trunnion axis, this situation is many, than the first situation coin, only has the situation of rotation of vertical axis many (power of finding afterwards this and alternating magnetic field after stator coil energising is relevant).Follow the rotation of trunnion axis, coin is merely able to a face in sight, another face " disappearance ".The situation of rotating along with each coin is different, sometimes sees front, sometimes sees reverse side, and two faces can not be seen simultaneously.From angle and position arbitrarily, go, be merely able to see a face of coin.
When coin rotates, see that the situation that two faces of coin coincide together is called " bird enters cage ", can only see a face of coin and situation that another face disappears is called " bird flies cage and loses ".Coin is merely able to while rotating in shaftless motor to see that the bird of a face flies cage and loses phenomenon and be called to rotate and interfere.
Matter wave: rotating interference is consistent with the interference of microcosmic particle, the duality principle of light, its fluctuation is, by light after slit, interference has occurred, this is static interference, two slit (or more slits, as grating) interference proved the fluctuation of light, and the particles such as electronics are called matter wave because can mutually interfere.When coin rotates, should see that bird enters the phenomenon of cage, but occur that bird flies the result that cage is lost, this is the interference that coin rotating manner causes, is called to rotate to interfere.If see the front of coin from the angle of oblique upper, what from the angle of oblique below, see so is exactly the back side of coin, oblique upper and the tiltedly difference of lower position are seen different fronts or the back side, the light and shade striped of this and interference of light phenomenon is in fact consistent, is therefore called the matter wave of macro object.
The feature of rotate interfering: feature one, trunnion axis rotates and relies on: coin, in the situation that rotating with trunnion axis, is merely able to see a face, and another face to can't see seem to have lost, bird flies the phenomenon that cage is lost, this is to rotate interference; If only have vertical axis to rotate, there is no the rotation of trunnion axis, two faces of coin can see, bird enters cage, and two faces overlap, and this rotation does not cause to rotate to be interfered.Feature two, monochromaticjty relies on: if the surface of a coin part is coated different colors, even if at this moment there is the rotation of trunnion axis, the part of these different colours bird still can not occur and flies the phenomenon that cage is lost, but in sight, the different colours on two faces partially overlaps together.Feature three, trunnion axis rotates the disappearance of dependence and monochromaticjty dependence: adopt multilayer coin as rotor (such as using 5 coins to stick together with 4 little thin discs ndfeb magnets), with shaftless motor, drive, rotor is too heavy, therefore can not rotate by occurred level axle, and the color of coin is different, such as 1 jiao different with 5 jiaos of coin colors, but still only see a face.Now, this rotation interference is just more consistent with interference of light.Interference of light is light and dark striped or the colored striped replacing, the feature of the rotor that multilayer coin forms is, observer's eyes move some positions, the coin surface of observing will replace, 1 jiao and 5 jiaos of coin picture on surface alternately, accordingly, rotate and interfere, kinetic interference, can regard interference equivalence that the slit with light causes as.Interference is the characteristic of ripple, and the coin that shaftless motor drives rotates and embodied the characteristic of interfering, the matter wave of Here it is macro object.
With stroboscope light source, observe the coin of rotation, with frequency converter, change the frequency of the alternating current of stator coil, when the stroboscopic frequency of coin rotating speed and stroboscope becomes integral multiple to be related to, feature and the principle of stroboscope work just broken through on the surface of the coin of seeing, this is also one of the rotation of coin important feature of interfering.
