Least common multiple is 48；The existing number of poles of 72 groove 24 pole non-brush permanent-magnet DC motors and the least common multiple of groove number are 72, can
With it is evident that number of magnetic poles provided by the present invention and groove array close (even minimum number) can significantly improve first-harmonic frequency
Rate, makes torque fluctuation amplitude be obviously reduced.
When design factor K value is 2, the value of quantity Z of described groove is 57, the quantity of magnetic pole be 14,57 groove 14 poles forever
The number of poles of magnetic DC brushless motor and the least common multiple of groove number are 798, the raising fundamental frequency that can become apparent from, to reduce
Cogging torque.
Still according to aforementioned exemplary, each winding distribution situation in groove is described when being 2 with design factor K value.
In the present invention, it is that the groove being wherein positioned at groove upper strata of U phase winding coil is all labeled as U, by V phase winding
Coil while the groove being positioned at groove upper strata is all labeled as V, by the equal labelling of the groove being positioned at groove upper strata of W phase winding coil
For W.
When concrete coiling winding coil, it is with the first groove for U phase winding starting point, with the 4th groove for V phase winding starting point, with
7th groove is W phase winding starting point.So, each groove being provided with winding coil is sequentially distributed as follows:
From the first groove, there is the groove combination UUWVV of M1 group, now, according to M1=Z-4*2P=57-4*14=1, it is known that have
1 group groove combination UUWVV, be disposed with in the most front 5 grooves U phase winding, U phase winding, W phase winding, V phase winding, V phase around
Group, and wherein the laying respectively at of the winding coil of above-mentioned U phase winding, U phase winding, W phase winding, V phase winding, V phase winding
Upper strata in front 5 grooves.Owing to the span of winding short distance winding involved in the present invention is 4, then the U phase in above-mentioned 5 grooves
Winding, U phase winding, W phase winding, V phase winding, the another side of winding coil of V phase winding i.e. lay respectively at the 4th groove, the 5th groove,
In 6th groove, the 7th groove, the 8th groove, and the another side of these coils is positioned at the lower floor of respective groove.
In like manner, there is the groove combination UWVV of M2 group, understand according to the computing formula of M2 and have M2=4, i.e. have the groove of four groups to combine
UWVV, order is distributed in the 6th groove to the 21st groove successively.
In like manner, there is the groove combination UWWV of M3 group, understand according to the computing formula of M3 and have M3=5, i.e. have the groove of five groups to combine
UWWV, order is distributed in the 22nd groove to 41 grooves successively.
In like manner, there is the groove combination UUWV of M4 group, understand according to the computing formula of M4 and have M4=4, i.e. have the groove of four groups to combine
UUWV, order is distributed in the 42nd groove to the 57th groove successively.
Thus, can show that 57 grooves are interior around group distribution list, the most as shown in table 1
Table 1
According to the relation between phase sequence labelling and the corresponding groove number described in above-mentioned table 1, it may be determined that go out in each groove around
Group distribution situation.
Wherein, the groove on the upper strata being wherein in each groove of U phase winding coil has: 1,2,6,10,14,18,22,
26、30、34、38、42、43、46、47、50、51、54、55；Corresponding, it is 4 according to winding coil span, it is known that U phase winding line
The another side of circle is respectively at the lower floor of following each groove successively: 4,5,9,13,17,21,25,29,33,37,41,45,46,49,
50、53、54、57、1.And by can get the U phase winding coil scattergram in each groove as shown in Figure 1 above.Can from Fig. 1
To find out, U phase winding coil with the 1st groove for U phase starting point, i.e. the power line of U phase, can regard the 1st groove as electric current enter to, will draw
To connecting terminal of motor.U phase winding be positioned at the coil of the 1st groove while being in the upper strata (indicated by the solid line) of the 1st groove, according to around
Group coil spread is 4, and the relative another side of described 1st slot coil is around the 4th groove, and is positioned at the lower floor of the 4th groove (by void
Line represents).It should be noted that in same groove, it is not necessary to an only phase winding coil, entirely possible another phase of existence around
Group coil.No matter whether the winding coil in same groove is same phase, is required to be positioned at the homophase of same groove in the present invention
The sense of current of winding coil wants consistent, and, further requirement is positioned at the sense of current of the homophase winding coil of adjacent slot
Also want consistent, and as standard coiling winding coil in each groove.It is to say, only consider when each winding coil is connected
The sense of current, and do not do head and the tail relation agreement.
As it is shown in figure 1, the relative another side in one side of described 1st slot coil is around the 4th groove, and it is positioned at the lower floor of the 4th groove,
Its sense of current can be considered to.Because being wound with two U phase winding coils of continuous print in the 1st groove, the 2nd groove, therefore sequentially,
The another side of winding coil from the 4th groove out after enter again the upper strata of the 2nd groove.It can be seen that the 1st adjacent groove and the 2nd groove, with
The sense of current of phase winding U phase winding coil is identical.The another side of the U phase winding coil come in from the 2nd groove goes out from the 5th groove
Come, and be positioned at the lower floor of the 5th groove.So, for the 1st groove, the 2nd groove, U phase winding coil be into；For the 4th groove,
For 5th groove, U phase winding coil be out to.From the 5th groove out after, coil should connect the coil that the 6th groove is corresponding, but, by
In the 5th groove for go out to, principle that should be identical according to the sense of current of the homophase winding coil of adjacent two grooves, the 6th groove also should
For go out to, then, the end of a thread of the 5th groove is connected to the 9th groove, make the 9th groove for enter to, then coil is returned from the 6th groove.With this type of
Push away, till the U whole coiling of phase winding coil is completed.
In like manner, V phase winding coil starts coiling from the 4th groove, and the upper strata of the 4th groove is V phase starting point and power line, the company of extraction
It is connected on connecting terminal of motor.7th groove is W phase starting point and power line, and same extraction is connected on connecting terminal of motor.So far,
The equal coiling of three-phase windings coil is complete, forms winding scattergram as shown in Figure 2.
Although embodiment of the present invention are disclosed as above, but it is not restricted in description and embodiment listed
Using, it can be applied to various applicable the field of the invention completely, for those skilled in the art, and can be easily
Realizing other amendment, therefore under the general concept limited without departing substantially from claim and equivalency range, the present invention does not limit
In specific details with shown here as the legend with description.
