Description
Affiliated technical field
The present invention relates to dynamo-electric field, especially a kind of electric device.
Background technology
Present electric device is more, its core majority is a motor, for motor, come branch can be divided into alternating current machine by the energy input, direct current machine, can be divided into synchronous machine again according to operation principle, asynchronous machine etc., then repeat no more as for other classification, yet, no matter which kind of motor, its primary structure is a stator and a rotor, wherein, stator can be made of coil, also can be permanent magnet, rotor is mainly by the coil coiled, for the cage motor, though some rotors do not have obvious coil, so copper bar that it adopted etc. has also constituted a kind of covert coil.
As mentioned above, the present motor that electric device adopted, its structure is comparatively complicated, show the layout aspect of coil, the stator coil of general alternating current machine needs to adopt three groups of coils at least, distribution setting according to specific could constitute rotating magnetic field, to drive rotor rotation, and the coil of rotor also will satisfy specific distribution relation, the rotating magnetic field that can cooperate stator to produce realizes the rotation of rotor, like this, the production cost of motor is higher, weight is big, and in a single day damages, and then maintenance is very inconvenient.
Summary of the invention
At the problems referred to above, the object of the present invention is to provide a kind of electric device, this electric device not only can be realized the continuous rotation of parts, and simple in structure, in light weight, cost is low, and is easy to maintenance.
The technical solution adopted for the present invention to solve the technical problems is: this electric device comprises rotor and stator, described stator is a loop coil, this coil is wound in an annular core outer surface, and connect a pulse power, described rotor comprises fanning strip and bus, each fanning strip evenly distributes around the rotating shaft that is arranged on described hub of a spool place, and each described fanning strip intersects the inclination angle that equates with the vertical plane of described rotating shaft, each described fanning strip is an electric conductor, is connected by equally distributed bus again between them.
As preferably, described fanning strip has 3-8 sheet and described bus by the one-body molded acquisition of metallic plate, is about to same metallic plate and carries out gas cutting, bending and get.
As preferably, described each bus surrounds the concentric concentric ring of a plurality of and described rotor center, and the bus of side surrounds a circular gabarit with whole rotor, to adapt to the annular trend of vortex flow.
As preferably, described iron core is the soft magnetic bodies iron core, as permalloy.
As preferably, the described pulse power is for only providing the sawtooth waveforms in ascender cycle.
As preferably, the spacing of described rotor and described iron core is not more than 2cm, with the loss of limiting magnetic flux.
As preferably, described coil arranged outside one deck shell, this shell is a non-ferromagnetic metal over against the face of described iron core, remaining face is nonmetal so that the magnetic field that produces of coil be compressed in the shell inboard, the loss of limiting magnetic flux.
Beneficial effect of the present invention is: this electric device is when work, external power source provides impulse wave to coil, and impulse wave has only the ascender cycle, then in the up process of impulse wave, the magnetic flux density that passes coil inside constantly increases, meanwhile produce vortex flow at rotor surface, according to Lenz's law, this vortex flow also is parallel to generation the magnetic field of inducting of rotor shaft, this magnetic field is opposite with the magnetic direction that coil is produced, to produce the recoil effect between the two, because the fanning strip of rotor is a hang plate, therefore under magneticaction, to as fan, rotate, and when an impulse wave end cycle, coil magnetic field disappears (having a transient process) fast, produces bigger reverse vortex flow in the rotor, and this vortex flow is offset previous forward vortex flow on the one hand, produce the opposing magnetic field on the other hand, yet the action time of this opposing magnetic field and coil magnetic field is extremely short, and is therefore minimum to the repulsion of rotor, rotor in the extremely short time, entered again impulse wave on the mechanism of line period, realize rotation continuously, this electric device not only can be realized the continuous rotation of parts, and simple in structure, in light weight, cost is low, and is easy to maintenance.
