The invention can generate two voltages at the same time, to improve the generating efficiency, and save material, reduce the cost, and reduce the weight. And it can be used in wind generation.
Description
Technical field
The invention belongs to electrical generator fields, especially a kind of synergy permanent-magnet-field generator.
Background technology
Conventional generator generally has only a rotor and stator.This rotor is packed on the armature spindle, is coated with rotor permanent magnet at its outer surface; Be fixed with stator on the inner surface of outer cover, on stator, be wound with winding coil.Be provided with bearing between shell and the armature spindle, armature spindle can rotate in bearing.Produce electric current by cutting magnetic line, efficient is lower, does not make full use of the function of permanent magnetic material.
For multichannel output generator, generator needs the interchange and/or the direct voltage output of multiple different amplitudes, so that provide electric power for different using electricity systems.Existing solution is that a plurality of different winding coils are set on same stator, obtains different voltage or electric current output with this.The shortcoming of the generator of this multichannel output is that generator can produce electromagnetic interference by the magnetic flux of magnetic circuit between the different windings when work, make voltage output fluctuate, thereby causes the unsteadiness of whole system work.
Summary of the invention:
The objective of the invention is to overcome the deficiencies in the prior art, provide a kind of simple in structure, cost is low, and the generating efficiency height can produce the synergy permanent-magnet-field generator of two voltages simultaneously.
The present invention solves its technical problem and takes following technical scheme to realize:
This synergy permanent-magnet-field generator, constitute by mandrel, overcoat, stator, rotor, bearing, on stator, be fixed with winding, it is characterized in that: the coaxial internal stator that constitutes by silicon steel sheet and winding that is fixed with on mandrel, this internal stator has a uniform symmetry on it to be fixed with the rotor of a plurality of permanent magnets with outer shaft sleeve, the inner edge of the armature spindle at the two ends of this rotor is installed by the seal cover board of bearing and overcoat by bearing and mandrel installation, outer rim, and outer casing inner wall is fixed with the winding external stator coaxial with mandrel.
And mandrel is a hollow structure.
And axial uniform symmetry is shaped on open-work on the rotor wall of rotor, setting-in permanent magnet on this open-work.
And the permanent magnet of employing is a Nd-Fe-B permanent magnet.
And, can axial uniform symmetry be shaped on 2n the open-work that can install permanent magnet on the rotor wall.
Advantage of the present invention and beneficial effect are:
The present invention has changed the existing structure of conventional electric generators, adopts the mode of a rotor, inside and outside two stators, during the rotor rotation, two stator while cutting magnetic lines produce two groups of electric currents, overall structure is very simple, and can produce two voltages simultaneously, and permanent magnetic material is fully used on generator, improved generating efficiency, saved material, reduced cost of electricity-generating, the total weight of generator alleviates, use lightly, be specially adapted to use in the wind power generation.
