Detailed description of the invention
The invention discloses a kind of generator system, have 6 owing to the magneto in generator system have employed stator inner wall
Individual stator slot, 6 stator slots are uniform along described stator inner periphery, and rotor is circular turn that 4 pieces of fan-shaped rare-earth permanent magnet steels surround
Son, the fixedly sleeved structure in described rotating shaft of rotor so that the starting reactance square relatively prior art of generator in generator system
In generator starting reactance square reduce 15%-31% so that the starting reactance of generator reduces suitable in generator system
When amplitude, it is ensured that the performance of generator and practical safety.
As it can be seen, Fig. 1 is the schematic diagram of generator stator and rotor in generator system of the present invention, including stator 1, rotor 3
With rotating shaft 4, stator 1 includes 6 stator slots 2, and stator winding is not shown, stator winding and generator one of the prior art
Sample is wrapped on the projection (the most non-groove portion) that adjacent stators groove 2 is formed.Wherein 6 stator slots 2 are along stator 1 inner periphery
Uniform, rotor 3 is the cylindrical rotor 3 that 4 pieces of fan-shaped rare-earth permanent magnet steels surround, and rotor 3 is fixedly sleeved in rotating shaft 4, turns
The radius of axle 4 is suitable with the inside radius of cylindrical rotor 3.
Wherein stator 1 preferably employs the stator that 50W470 cold-reduced silicon sheet thick for 0.5mm is piled into.Because prior art is sent out
The stator of motor generally uses DG310-0.2 silicon steel sheet, and this material is mainly used in high frequency occasion, domestic the most several
Individual steel mill produces, and yields poorly, and price is high, and the order cycle time is long.And generator each working time of generator system of the present invention is only
Having several seconds, rotating speed 2000r/min, frequency is the highest, and the loss that eddy current causes is negligible.Therefore 0.5mm is used
Thick 50W470 cold-reduced silicon sheet.The performance of generator is not adversely affected by the replacement of this material, also reduces material
The problem of cost.
Preferably, epoxy glue entirety embedding structure is used between stator 1 and stator winding.Because so so that stator winding
It is enclosed in reliably in epoxy glue with stator 1.Such a construction increases the mechanical strength of stator winding, improve radiating condition,
In wet environment, not only do not result in the destruction of stator winding insulation, though the special adverse circumstances that generator is immersed in water,
Can normally work equally, thus be effectively increased the environmental suitability of generator.
As shown in Figure 2,3, Fig. 2 is generator amature cutting and assembling schematic diagram in generator system of the present invention, and Fig. 3 is this
In bright generator system, generator amature combines schematic diagram with rotating shaft.It is several equal-sized by rare earth permanent magnet steel bar is cut into
Secter pat, is then connected in rotating shaft 4 by Wear Characteristics of Epoxy Adhesive, forms rotor 3.4 pieces of fan-shaped rare earth permanent magnets of its rotor 3 are firm
It is preferably NdFeB rear-earth magnet steel, more preferably N-33SH Nd-Fe-B magnet steel.4 pieces of fan-shaped rare-earth permanent magnet steels of rotor 3 interior

Nd-Fe-B permanent magnet material, it is not necessary to p-m rotor 3 is carried out entirety and magnetizes, so inventor is preferably by tile type neodymium iron boron
Magnet steel instead of Casting Al-Ni-Co Magnet.Rotor 3 structure uses direct adhesive permanent magnetism body in the rotating shaft 4 of annular knurl, outside magnet steel
Surface adds aluminium ring 6 and reinforces at rotor 3 magnet steel two ends epoxy glue 7.It is greatly simplified that this structure makes rotating shaft 4 process, technique
Simply, processing cost is reduced.In order to verify the Mechanical Reliability of this structure, the moment of torsion that can bear magnet steel outer rim is surveyed
Examination.It is 0.017N m by the nominal torque that can be calculated generator amature, the minimum 3-of moment of torsion that actual measurement model machine rotor can bear
5N m, is more than 170 times of nominal torque, is much higher than the index of 50 times of values of routine, meets generator system pair of the present invention
The requirement of generator mechanical reliability.
Leaving air gap between inwall and the outer wall of rotor in the non-groove portion of stator, the size of described air gap is 0.1mm-1.35mm,
It is such as 0.1mm, 0.30mm, 0.35mm, 0.70mm, 0.90mm, 1.00mm, 1.15mm, preferably void dimension
For 1.35mm.The monolateral only 0.1mm of the stator and rotor air gap of generator in prior art, thus to generator in generator system
Parts machining and final assembly propose high requirement.In generator system of the present invention, generator is more excellent owing to have employed performance
Different Nd-Fe-B permanent magnet material, the magnetic loading of generator obtains bigger raising so that under same volume, the performance of generator shows
Write and improve.According to generator principle, electromotive force Ea=Ce φ n lies prostrate, and the Ce=pN/60a in formula is referred to as back EMF constant, main
Will be with number of pole-pairs p, circuitry number a and conductor number N is relevant；φ is every pole air-gap flux；N is the rotating speed of p-m rotor.If
During the technology of generator system requires, clear stipulaties stator DC resistance and generator speed, i.e. Ce and N determine the most substantially,
If stator and rotor air gap also keeps constant, then make Ea improve the most therewith the bigger raising because of φ, due to every pole air-gap flux φ with
Stator and rotor air gap is inversely proportional to, and stator and rotor air gap is brought up to 1.35mm, is computed the useful flux φ keeping air gap with existing
There is the useful flux φ in technology basically identical, therefore ensureing performance and the prior art of generator in generator system of the present invention
In the case of the performance of middle generator is essentially identical, the stator and rotor air gap of generator in generator system of the present invention is increased by inventor
Greatly to 1.35mm, both ensure that the performance of generator in generator system of the present invention, and also made generator system of the present invention generates electricity
