Abstract
The charging power set is a permanent magnetic outer rotor type one with peripheral permanent magnets in interval of 0.5-0.8 time the width; single phase winding embedded inside the stator groove; stator groove in special shape and size; stator shaft twisted relatively to the axis with the total twisting amount being 12 times the slot width; and stator winding divided into several groups. Each of the windings has the output connected via reactor to AC side of rectifier, and the DC outputs of the rectifiers are connected serially and parallelly to combine varying DC output voltage for charging different load. The power set has high power-to-volume ratio, small volume, light weight, high conversion efficiency and good charging characteristic. The power set is used as DC power supply for constant current charging and fast charging and may be also used as other DC power supply.

Background technology
There is not custom-designed generating set at present for charging usefulness, the generating set that existing bavin, gasoline-engine driven machine drive as charging, just generating set charges by other commutation system.The composition of its generator and engine be substantially two separate components and close.Motor itself adopts conventional structure, and volume is big, Heavy Weight, efficient are low, and it is bigger to add charger weight.
The technical problem to be solved in the present invention is to improve generator Structure, makes it be directly used in charging, and the performance number of the unit volume of generating increases, weight saving, constitutes indivisible integral structure with engine, has improved serviceability greatly.
Summary of the invention
Technical scheme of the present invention is:
A kind of charging machine group, the rotating shaft of generator directly connects the output shaft of engine, and the stator of generator is fixed on the engine; Stator is established groove, be embedded winding in the groove, it is characterized in that: the flute profile of described stator slot is: with the generator cross-section center is that the hypothesis circle is set in the center of circle, this circular diameter is (1/3-2/3) of internal stator diameter when the internal stator situation or is (3-3/2) of external stator diameter when the external stator situation, make the tangent line of hypothesis circle to described hypothesis circle from notch, limit cell wall, limit bottom land by groove depth, this groove depth and cell wall limit flute profile jointly; Slot opening approximates the facewidth; Rotor is a permanent-magnet type, and the width of cloth alternately is provided with on circumference to magnetized N, S permanent magnets, and the distance between the adjacent permanent magnets is permanent magnets circumferential width (0.5-0.8); Winding on the full stator is divided into a plurality of independent parts, these a plurality of independent winding insert the interchange end of rectifier bridge separately by a little reactor respectively, and the dc output end of rectifier bridge is by parallel connection, series connection or the variable direct voltage of series-parallel connection form output, for load is charged.On output circuit, can be connected to two transducers, autostop after the detection storage battery abundance, Auto Power On behind another detection storage battery power shortage.Further, this routine described generator also makes the relative axis skew of notch on the stator shaft orientation, and the skew amount is (1.1-1.3) of groove width on the stator total length.
The charging generator group that this programme is realized, than the unit of prior art, power to volume ratio height not only, overall volume is little, and is in light weight, the conversion efficiency height, and good charging characteristic is arranged.This unit can be done constant current charge and boost charge fast, also can be used as other DC power supply.

Embodiment
Be described in detail embodiment below in conjunction with accompanying drawing.
Fig. 1 is that generating set of the present invention and engine connect schematic diagram.Generating set comprises engine 1, directly is connected in the generator amature 3 in the engine rotating shaft and be fixed on generator unit stator 2 on the engine casing.That is, generating set of the present invention is the incorporate machine of engine and generator.Engine is gasoline engine or diesel engine.
Generator power in this example is 2.7KW, 56 utmost points, and 112 grooves, generator speed 3000rpm is a kind of generator of external-rotor-type, but and nonessential like this.
Stator 2 is the cylinders that built up by silicon steel sheet, is provided with a plurality of grooves in its excircle, and Fig. 2 is the structural representation that groove forms, R
1Be stator outer radius, R
2Be the radius of decision groove depth, R
3Be fluting hypothesis radius of a circle, R
4Be diameter of stator bore.Described hypothesis radius of circle R
3Be stator outer diameter R
1(1/3-2/3), when generator is inner rotor core, described hypothesis circle circle outside in stator, this ratio certainly will be conversely, is (3-1.5).R in this example
1Be 90mm, R
3Be 60mm.A plurality of teeth groove are uniform on the stator periphery, and AB is that width of rebate, BC are facewidth degree, AB ≈ BC, and promptly the facewidth approximates groove width.From the A and the B point of notch, make tangent line to the hypothesis circle, gained two lines define the cell wall of this groove, and groove depth limits bottom land, and groove depth is by R in this example
2Decision.Uniform a plurality of permanent-magnet poles on the rotor internal cavity periphery, it is that the width of cloth forms along circumferentially alternately arranging to the N that magnetizes, S polarity permanent magnets, the distance of getting in this example between the adjacent permanent magnets is 0.5 to the ratio of permanent magnets width, in general, this ratio can be (0.5-0.8), and promptly pole span of rotor is permanent magnets width (1.5-1.8).The number of stator slots of occupying in every pole span scope is looked designing requirement and is determined that in 24 scopes this example is 2, and generator has technical indicator preferably.The cylinder that the stator silicon steel sheet builds up has the notch of skew, referring to Fig. 3, promptly to notch position A at stator shaft orientation one end, " opposing parallel moves past a skew amount (A '-A ") in the A-A ' line of axis stator at the corresponding notch position A in stator shaft orientation other end place for it, this skew amount is (1.1-1.3) of groove width, is 1.2 in this example.Referring to Fig. 4; winding on the full stator of stator slot divides 8 independent parts; 8 independent winding insert the interchange end of 8 rectifier bridges separately respectively by a little reactor L; and the dc output end of 8 rectifier bridges is by the direct voltage of change over switch by parallel connection, series connection or connection in series-parallel mixed form output 12-240V; for the constant current charging is done in load; on output circuit, can be connected to two transducers, autostop after the detection storage battery abundance, Auto Power On behind another detection storage battery power shortage.
