Description
Technical field
The present invention relates to magneto, specifically a kind of center cylindricality permanent magnet sources type " pawl pole " formula magneto, comprise center cylindricality permanent magnet sources type each shape " pawl pole " formula permanent magnet generator and center cylindricality permanent magnet sources type each shape " pawl pole " formula permanent magnet motor, and each shape " pawl pole " formula permanent magnet generator, electric integral machine etc.
Background technology
Magneto, comprises permanent magnet generator and permanent magnet motor, and its remarkable advantage is that energy utilization efficiency is higher." the automobile-used pawl pole magneto generator of low-speed running " of publication number CN203554246U, its permanent magnet is be arranged on the annular permanent magnet between alternator shaft and pole pawl, arrange a fact between this annular permanent magnet and rotating shaft not exist " every the magnetic lining " with " every magnetic " function, if rotating shaft uses magnetic material to make, then still there is more serious leakage field phenomenon.
Summary of the invention
For problems such as prior art are not enough, the present invention announces a kind of center cylindricality permanent magnet sources type " pawl pole " formula magneto, cylindricality permanent magnet sources in such magneto comprises one or more cylindricality permanent magnet, by yoke dish, the magnetic pole of cylindricality permanent magnet is drawn into multiple new magnetic pole, to realize and to meet various power, the permanent magnet generator of rotation speed requirements and permanent magnet motor.
Realizing technical scheme of the present invention is: cylindricality permanent magnet sources type " pawl pole " formula magneto center, center is provided with one or more cylindricality permanent magnet and more than two (containing two) yoke dishes, comprises " the pawl pole " containing yoke dish.
Technical characteristics of the present invention is: the cylindricality permanent magnet at cylindricality permanent magnet sources type " pawl pole " formula magneto center, center is axial magnetized, it is the permanent magnet sources element of motor of the present invention, the pole end piece of cylindricality permanent magnet is glued with the yoke dish be made up of soft magnetic material, comprise " the pawl pole " containing yoke dish of being made up of soft magnetic material, the effect of yoke dish changes axial magnetic flux into radial magnetic force line exactly, the magnetic line of force evenly spreads to pole pawl again and forms some new magnetic poles, center cylindricality permanent magnet sources type " pawl pole " the formula magneto always installed enters the yoke dish of cylindricality permanent magnet pole end primarily of position, " pawl pole " containing yoke dish and stator core form closed magnetic circuit.
In cylindricality permanent magnet sources type " pawl pole " the formula magneto of described center, because the permanent magnet sources number of elements used is less, except can traditionally motor production model be arranged in advance except the center of magneto, also can adopt and first reserve the space of laying cylindricality permanent magnet sources element in motor center position, when rotor and stator relative positioning, again cylindricality permanent magnet sources element is imported to the headspace position of motor center along pipeline or axle, or release motor from motor center position, with in the assembling and maintenance process of magneto of the present invention, major part work is realized without magnetization operation.
The cylindricality permanent magnet sources element of described center cylindricality permanent magnet sources type " pawl pole " formula magneto, when comprise multiple cylindricality permanent magnet and stacking according to same polarity adjacent fashion again time, add a cylindricality soft magnetic bodies betwixt, can be stacking smoothly and draw a common magnetic pole, thus formed one overall, compound
many magnetic poles typecylindricality permanent magnet sources.
Described center cylindricality permanent magnet sources type " pawl pole " formula magneto, settle between two parties for convenience of permanent magnet, except positioner mode is set up in employing, in the pole end piece of cylindricality permanent magnet and yoke disk center, centre bore can be set respectively, and guarantee that each permanent magnet and each yoke dish remain on same center line by inserting centering rod member mode.If when permanent magnet centre bore is through-core hole, then the centering bar material inserting centre bore must be nonmagnetic substance or weak magnetic material, otherwise there will be more serious leakage field phenomenon.
" pawl pole " quantity of described center cylindricality permanent magnet sources type " pawl pole " formula magneto is main relevant with the number of magnetic poles of cylindricality permanent magnet sources, increases number of magnetic poles and " pawl pole " number, is conducive to the operate power improving magnetic energy utilization efficiency and magneto; " pawl pole " shape then draws the magnetic pole strength of magnetic to stator core to different and different with the position residing for " pawl pole " relative stator iron core with " pawl pole ", when the magnetic pole strength of " pawl pole " is radial, then comprise unidirectional stretching, extension and two kinds, Biextension pawl pole, this kind of pawl discloses and widely used pawl pole very at present, and the rotor formed and stator are generally cylindrical shape; And the magnetic pole strength of working as " pawl pole " for axially or oblique time, then include single magnetic pole strength and two magnetic pole strength shape " pawl pole " two kinds, this kind of pole claw type is as " the sucker pawl " of lizard, and its rotor and stator are generally disc or cone disc.
Center of the present invention cylindricality permanent magnet sources type " pawl pole " formula magneto major advantage: the permanent magnet negligible amounts that magneto really uses, structure is simple, compact, energy conversion efficiency is high, production cost is low, in magneto, cylindricality permanent magnet sources element is easily dismantled, is changed, electrical machinery life is long, is suitable for the various power of design, each shape " pawl pole " formula permanent magnet generator, permanent magnet motor and the permanent magnet generator of rotation speed requirements, electric integral machine.At motor center headspace, rear lead-in mode, cylindricality permanent magnet sources element is installed if adopt simultaneously, magneto can also be realized without magnetization assembling, machinery debugging and maintenance.
