The explanation of the loop length of each winding turns of＜the 2 winding layers W2 〉

The 2nd winding layers W2 finished at the winding process of the 1st winding layers W1 the back is overlapping reels on it.Each winding turns of the 2nd winding layers W2, even in each grooving 22, in addition at the end face of armature core 21, also be that the overlapping coiling of each winding turns with the 1st winding layers W1 forms, thereby the loop length of each winding turns of the 2nd winding layers W2, all greater than the winding turns T14 among the 1st winding layers W1, the loop length of T24 with maximum coil length.

In addition, the coiling zone W21 of the 2nd winding layers W2, winding turns T15, T16 till will be from No. 1 to No. 4, T17, T18 reel successively continuously and form, and in addition, the regional W22 that winds the line reels winding turns T25, T26, T27, T28 till from No. 1 to No. 4 successively continuously and forms.No. 1 winding turns T15 of regional W21 of winding the line is wound on No. 4 last winding turns T14 of the regional W11 of coiling continuously, and No. 1 winding turns T25 of the regional W22 that winds the line is wound on No. 4 last winding turns T24 of the regional W12 of coiling continuously.On the left end face of armature core 21, the part of No. 2 winding turns T16, T26 is overlapped No. 1 winding turns T15, T25 reels lastly, the part of No. 3 winding turns T17, T27 is overlapped these No. 2 winding turns T16, T26 reel lastly, and the part of No. 4 winding turns T18, T28 is overlapped No. 3 winding turns T17, T27 reel lastly.Therefore, when the loop length with each winding turns T15, T16, T17, T18 and T25, T26, T27, T28 is made as t15, t16, t17, t18 and t25, t26, t27, t28, then become the relation of t15＜t16＜t17＜t18, in addition, become the relation of t25＜t26＜t27＜t28.

＜to the explanation of the deviation of the resistance value of the 1st, the 2nd winding assembly U1, U2 〉

The 1st winding assembly U1 is made of the coiling zone W21 of coiling zone W11, the 2nd winding layers W2 of the 1st winding layers W1.These wind the line regional W11, W21, mutually continuously, and overlapped coiling.Each winding turns T11, T12, loop length t11, the t12 of T13, T14, t13, the t14 of regional W11 of winding the line becomes the relation of t11＜t12＜t13＜t14, in addition, the relation that each winding turns T15, T16, loop length t15, the t16 of T17, T18, t17, the t18 of regional W21 become t15＜t16＜t17＜t18 that winds the line is very important.Winding turns T11, T18 connects between adjacent commutator segment is to h-a mutually side by side, winding turns T12, T27 connects between adjacent commutator segment is to g-h mutually side by side, winding turns T13, T26 connects between adjacent commutator segment is to f-g mutually side by side, winding turns T14, T15 connects between adjacent commutator segment is to e-f mutually side by side, thereby according to the relation of above-mentioned loop length, each adjacent commutator segment is between the a-h, adjacent commutator segment is between the g-h, adjacent commutator segment between the f-g and adjacent commutator segment the combined resistance value of each coil between the e-f is become the more value of homogeneous.

In addition, the 2nd winding assembly U2 is made of the coiling zone W22 of coiling zone W12, the 2nd winding layers W2 of the 1st winding layers W1.These wind the line regional W12, W22, mutually continuously, and overlapped coiling.Also identical for the 2nd winding assembly U2 with the 1st winding assembly U1, realize the homogenization of resistance value.Loop length t21, t22, t23, the relation that has t21＜t22＜t23＜t24 between the t24, in addition, loop length t25, t26, t27, the relation that has t25＜t26＜t27＜t28 between the t28, thereby the winding turns T21 that between adjacent commutator segment is to d-e, connects side by side, the combined resistance value of T28, the winding turns T22 that between adjacent commutator segment is to c-d, connects side by side, the combined resistance value of T27, the winding turns T23 that between adjacent commutator segment is to b-c, connects side by side, the combined resistance value of T26, the winding turns T24 that between adjacent commutator segment is to a-b, connects side by side, the combined resistance value of T25 becomes the more value of homogeneous.

Fig. 5 is the figure of each adjacent commutator segment of expression example 1 to the deviation of the resistance value of the armature winding between a-h, g-h, f-g, e-f, d-e, c-d, b-c, the a-b 25.In Fig. 5, each resistance value of establishing winding turns T11, T12, T13, T14, T15, T16, T17, T18 is respectively R11, R12, R13, R14, R15, R16, R17, R18.If each resistance value of winding turns T21, T22, T23, T24, T25, T26, T27, T28 is respectively R21, R22, R23, R24, R25, R26, R27, R28.In addition, establish each adjacent commutator segment each combined resistance value between a-h, g-h, f-g, e-f, d-e, c-d, b-c, the a-b is respectively Rah, Rgh, Rfg, Ref, Rde, Rcd, Rbc, Rab.

Resistance value R11, R12, R13, R14 increase to R14 from R11 successively according to the relation of t11＜t12＜t13＜t14, and in addition, resistance value R15, R16, R17, R18 increase to R18 from R15 successively according to the relation of t15＜t16＜t17＜t18.Combined resistance value Rah, Rgh, Rfg, Ref are respectively the combined resistance value arranged side by side of resistance value R11 and R18, R12 and R17, R13 and R16, R14 and R15, but from resistance value R11 to the increase direction of R14 with opposite to the increase direction of R18 from resistance value R15, thereby the deviation of the combined resistance value Rah of the 1st winding assembly U1, Rgh, Rfg, Ref can be suppressed in less below 10%.

Equally, resistance value R21, R22, R23, R24 increase to R24 from R21 successively according to the relation of t21＜t22＜t23＜t24, and in addition, resistance value R25, R26, R27, R28 increase to R28 from R25 successively according to the relation of t25＜t26＜t27＜t28.Combined resistance value Rde, Rcd, Rbc, Rab are respectively the combined resistance value arranged side by side of resistance value R21 and R28, R22 and R27, R23 and R26, R24 and R25, but from resistance value R21 to the increase direction of R24 with opposite to the increase direction of R28 from resistance value R25, thereby the deviation of the combined resistance value Rde of the 2nd winding assembly U2, Rcd, Rbc, Rab can be suppressed in less below 10%.

Fig. 6 represents the deviation of resistance value of the armature winding of traditional direct current machine.In this Fig. 6, in order to compare, identical with example 1, the grooving number is 8, making armature is 2 layers of internal layer side winding layers and outer layer side winding layers, these internal layer side winding layers and outer layer side winding layers are all with overlapping winding method, and between each commutator segment, lower floor's winding turns of 20 circles is connected side by side with the upper strata winding turns of 20 circles.Internal layer side winding layers staggers 8 each winding turns to each 1 grooving pitch successively on one side and reels on one side towards the direction of stipulating.The outer layer side winding layers is on this internal layer side winding layers, Yi Bian Yi Bian 8 each winding turns each 1 grooving pitch ground are successively staggered towards identical prescribed direction reel.

In this Fig. 6, the resistance value R11 to R18 of each winding turns between each commutator segment of internal layer side winding layers, increase towards right successively to R18 from R11, in addition, the resistance value R21 to R28 of each winding turns between each commutator segment of outer layer side winding layers also is to increase to right successively to R28 from R21.Combined resistance value Rah between each commutator segment of the direct current machine that this is traditional, Rgh, Rfg, Ref, Rde, Rcd, Rbc, Rab, in Fig. 6, increase successively towards right, thereby adjacent commutator segment is a minimum value to the combined resistance value Rah between the a-h, adjacent commutator segment is a maximum to the combined resistance value Rab between the a-b, and its deviation reaches 40%.

In this example 3, (n+1-m) the winding turns of m number (m from 1 to 8) in the individual winding turns of the n of the 1st winding layers W1 (n=8) and n the winding turns of the 2nd winding layers W2 number winding turns becomes and the identical relation of adjacent commutator segment to being connected, its result, can suppress combined resistance value Rag, Rgh ..., Rab deviation, can suppress the torque ripple in the direct current machine rotation.

[example 4]

In example 1～3, each winding turns T11～T18 of armature winding 25 and the winding number N of T21～T28 are 20 identical circles, but in the example 4, in the 1st, the 2nd winding layers W1, W2, make the winding number N that is slightly smaller than the winding turns of reeling previously near the winding number N of last winding turns of reeling.

Such as, all be taken as 20 with constituting the winding turns T11～T14 of the 1st winding layers W1 of internal layer side of the 1st winding assembly U1, U2 of example 1 and the winding number N of T21～T24, winding turns T15～T18 till No. 1 to No. 4 of the 2nd winding layers W2 of outer layer side and the winding number N of T25～T28 are taken as 18,19,20,20.Specifically, the winding number of the 2nd winding layers W2 No. 1 winding turns T15, T25 is that the winding number of 18, No. 2 winding turns T16, T26 is 19.

In Fig. 5, adjacent commutator segment to combined resistance value Rbc, the Rab of combined resistance value Rfg, the Ref of f-g, e-f and b-c, a-b greater than the right combined resistance value of other adjacent commutator segments, but by regulating the winding number of winding turns T15, T25 and T16, T26, these combined resistance values can be further reduced, the deviation of combined resistance value can be further suppressed.

In example 1, the winding number of No. 3 winding turns T13, the T23 of the 1st winding layers W1 of internal layer side is adjusted to 19, it also is effective that the winding number of its No. 4 winding turns T14, T24 is adjusted to 18.This occasion, the winding number of other winding turns all is taken as 20.

Be applicable to example 2,3 too by next synthetic resistance value is regulated of the adjusting of winding number N.In example 3, from the 1st winding layers W1 of internal layer side from No. 1 to No. 5 till the winding number of winding turns all be 20, the winding number of its No. 6 winding turns T16 is adjusted to N=19, the winding number of its No. 7 winding turns T17 is adjusted to N=18, the winding number of its No. 8 winding turns T18 is adjusted to N=17, also is effective.Again, in example 3, the winding number of its No. 1 winding turns T21 is adjusted to N=17, and the winding number of its No. 2 winding turns T22 is adjusted to N=18, and the winding number of its No. 3 winding turns T23 is adjusted to N=17, and it also is effective that the winding number of other winding turns is adjusted to 20.

[other examples]

From example 1 to 4, the grooving number all is 8, but the present invention is equally applicable to have in addition the direct current whirler of any grooving number.Especially, grooving is counted S in the occasion below 12, because reduce to cut apart simultaneously the number of the winding assembly of reeling, torque ripple increases.Fig. 9 is the figure of this trend of expression, and transverse axis is that grooving is counted S, and the longitudinal axis is torque ripple %.The characteristic Y1 of solid line is a characteristic of utilizing the direct current machine of traditional method for winding, and the characteristic Y2 of dotted line is a characteristic of utilizing the direct current machine of method for winding of the present invention.Especially, grooving is counted S in the scope below 12, and traditional method for winding sharply increases torque ripple, and method for winding of the present invention can suppress the increase of this torque ripple.

Count S for grooving, be not limited to even number, the present invention is also applicable to the direct current whirler with odd number grooving.But, grooving is counted the occasion that S is an even number, and the excitatory power radially that armature winding 26 causes is in the relation of cancelling out each other in symmetrical position with respect to the axis of rotating shaft 10, can further reduce the influence of torque ripple, so preferably be taken as even number.

In addition, for winding mode, example 1 to 4 all is overlapping winding method, but is equally applicable to the waveform winding method.The waveform winding method, n the winding turns of reeling successively till the winding layers of internal layer side and the winding layers of outer layer side also have from No. 1 to n number respectively, respectively with a winding turns part of reeling the previously following winding turns of reeling overlappingly, its loop length has the trend that increases successively, so can be suitable equally.
