Specific embodiment
As shown in Figure 1, the machine winding proposed in the utility model embodiment, which can apply turns in stator
On son.The machine winding includes polyphase windings, and the umber of turn at least two different phases is not identical, with the umber of turn in phase
It is identical.
As depicted in figs. 1 and 2, the stator proposed in the utility model embodiment, the stator include stator core 10 and determine
Sub- winding 20, stator core 10 include cricoid stator yoke 11 and be arranged on the inner wall of stator yoke 11 along the stator core
Circumferentially spaced multiple stator tooths 12, stator winding 20 are wrapped on stator tooth 12.
Stator winding 20 in the present embodiment uses above-mentioned machine winding, i.e. the stator winding 20 includes polyphase windings,
Umber of turn at least two different phases is not identical, identical with the umber of turn in phase.
The winding number of phases 20 is at least two-phase, can be two-phase, three-phase, four phases, five mutually even more.At least two different phases
In umber of turn it is not identical, it is identical with the umber of turn in phase.
In the present embodiment, which is three-phase (such as A phase, B phase and C phase), the winding turns in these three different phases
Number it is not identical, i.e., the umber of turn in A phase and the umber of turn in B phase, C phase be not identical, the umber of turn in B phase in C phase
Umber of turn it is also not identical.For example, the umber of turn in A phase is N1, the umber of turn in B phase is N2, the winding turns in C phase
Number is N3, N1 ≠ N2 ≠ N3.
In the present embodiment, the quantity of stator tooth 12 is nine, with three stator tooths 12 in phase, differs 120 ° between any two
Setting.For in Fig. 2, three stator tooths of serial number 1,4 and 7 differ 120 ° between any two, are A phase；Serial number 2,5 and 8
Three stator tooths, between any two differ 120 °, be B phase；Three stator tooths of serial number 3,6 and 9, differ between any two
120 °, be C phase.Serial number 1,4 is identical with the umber of turn on 7 stator tooth, is N1；On the stator tooth of serial number 2,5 and 8
Umber of turn it is identical, be N2；Serial number 3,6 is identical with the umber of turn on 9 stator tooth, is N3.Phases different in this way
