The utility model has the advantages that the armature winding and harmonic winding of a motor only form a double-layer winding and have no mutual inductance relation and no disturbance thereby making the dynamic electrical property of the motor well, and a line voltage waveform distortion rate of the three-phase armature winding in the motor is less than 2%, and also the motor has good electric property and electromagnetic compatibility.
Description
Technical field
The utility model relates to a kind of Dispersal Type Single Or Double-layer Three-phase Alternating-current Winding Generator.
Background technology
As everyone knows, the synchronous threephase generator of modern brushless, in order to improve the ability of band nonlinear load, the stator armature winding of generator is popular to be designed to short distance 2/3 or to approach 2/3 winding.For example, a kind of well-known famous brand brushless three-phase synchronous generator, number of stator slots is 48 grooves, number of poles is 4 utmost points, the number of phases is 3 phases, and the armature winding number of turn that whenever is in series is 36 circles, and the parallel branch number is a=2, and every groove conductor number is 9, every extremely every phase groove number is 4, and the number of turn is arranged by 4,5,4,5, and pitch is 9, be span 1-10, two repeatedly double-deck, and humorous wave winding is single-phase concentric type, laxative remedy is span 1-4,8 circle/circles, totally 12 circles, span 2-3,4 circle/circles, totally 12 circles.Therefore every groove has three layers of winding in the stator.The winding number of plies is many in this motor stator, and armature winding and humorous wave winding can't form no mutual inductance position, influences the dynamic electrical performance of motor.
Summary of the invention
The purpose of this utility model provides a kind of Dispersal Type Single Or Double-layer Three-phase Alternating-current Winding Generator, and its armature winding and humorous wave winding form no mutual inductance, make simultaneously in the every groove of stator and have only double-layer winding, and other electrical property of armature winding can not reduce.
The utility model is achieved like this, it comprises stator and rotor, it is characterized in that: number of stator slots is 48 grooves, number of poles is 4 utmost points, and the number of phases is 3 phases, and the parallel branch number is 2, threephase armature winding span has three kinds, is respectively 1-12,2-11,4-9, and the every circle of the number of turn is respectively 5,9,4 from big span to little span, three phase windings like this are in stator 48 grooves, it is individual layer that 24 grooves are arranged, and 24 grooves is arranged for double-deck, the coil of three kinds of spans,, not dispersal type by groove number successively arrangement.Single-phase humorous wave winding span is 1-4, and the parallel branch number is 1, down in 24 individual layer grooves of stator armature winding.This two covers winding of threephase armature winding and single-phase humorous wave winding only constitutes double-layer winding in the stator in 48 grooves like this, and 30 ° of the center line mutual deviations of humorous wave winding and armature form no mutual inductance relation, and are noiseless mutually.
The utility model has the advantages that: armature winding of (1) motor and humorous wave winding form no mutual inductance relation, and noiseless mutually, the dynamic electrical performance of motor is good; (2) the line voltage-form distortion rate of the threephase armature winding of motor has good electric property less than 2%; (3) Electro Magnetic Compatibility is good.
Description of drawings
Fig. 1 is a three-phase developed winding diagram of the present utility model;
Embodiment
With the 90KW generator is example, and as shown in Figure 1, U, V, W, N go out wire tag for the threephase armature winding among the figure, the three-phase and four-line standard, and S1, S2 are humorous wave winding outlet mark, S3 is the tapped mark of humorous wave winding.Generator unit stator 48 grooves, number of poles is 4 utmost points, the number of phases is 3 phases, the armature winding three-phase, the parallel branch number is 2, and the number of turn is respectively 5,9,4 circles, and the threephase armature winding of Xing Chenging is called dispersal type list Double-layer AC winding like this, also being in the groove 2,3,6,7,10,11,14,15,18,19,22,23,26,27,30,31,34,35,38,39,42,43,46,47, having only one deck armature winding in totally 24 grooves, is double-deck armature winding in all the other 24 grooves.And humorous wave winding coil span is y=1-4, and the parallel branch number is 1, and it is down in the groove of above-mentioned individual layer armature winding.
This arranged makes in the stator slot two cover windings only form double-layer winding, there are not three layers of winding, saved layer insulation and rolled off the production line man-hour, and shortened stator winding end, and 30 ° of electrical degrees of the central axis inequality of the central axis of humorous wave winding and armature winding, then the triple-frequency harmonics winding has formed no mutual inductance relation for differing from 30 ° * 3=90 °.According to span y=1-12,2-11,4-9, the fundamental wave winding coefficient of the armature winding that the number of turn 5,9,4 is arranged with arrange by the number of turn 4,5,4,5, the fundamental wave winding coefficient of two double-deck armature winding that change that span y=1-10 arranges is respectively 0.8848 and 0.8726, and the mechanical pitch of single two layer winding equivalence is (5 * 11+9 * 9+5 * 4)/18=8.667, also lack than 9 of y=1-10, so the two fundamental voltage performance is suitable, and these two kinds of armature winding harmonic contents also are suitable.The advanced development result, the line voltage-form distortion rate is less than 2%, and the phase voltage waveform aberration rate has good electric property less than 5%.The basic electrical characteristics of the double-deck armature winding of this dispersal type list are not less than former in the number of turn 4,5,4,5 arrangements, and span is two repeatedly two layer winding that y=1-10 arranges.So just reached the purpose of invention comprehensively.
