Description
Technical field
The utility model belongs to design of electrical motor field, is specifically related to a kind of three-phase double salient-pole electric machine armature winding structure.
Background technology
Double salient-pole electric machine is a kind of new special motor grown up in recent years, its rotor is tooth slot structure, concentrated armature winding and excitation winding stator be equipped with, windings in series on the stator tooth that space is relative forms a phase, without winding on rotor, structure is simple, dependable performance, therefore the application of double-salient-pole is more and more extensive, also proposes more and more higher requirement to the performance of double-salient-pole simultaneously; But due to the design feature of double-salient-pole itself, the placement as stator grooved, excitation winding cause double salient-pole electric machine itself structure asymmetric, the problem such as cause armature electric current asymmetric, and then cause the decline of motor performance.
Utility model content
Utility model object: the utility model solves the problems referred to above, proposes a kind of three-phase double salient-pole electric machine armature winding structure, improves the asymmetric of armature supply, improves motor output torque, reduces torque pulsation, and then improves the performance of motor.
Technical scheme: a kind of three-phase double salient-pole electric machine armature winding structure, comprises excitation winding, armature winding and stator poles, and described toothed stator pole has several, surrounds circle, is provided with stator slot between adjacent stator pole; Described armature winding by stator slot around in stator poles; An excitation winding is provided with in described two stator slots of being often separated by; The number of turn of the armature winding that the stator poles of described excitation winding both sides is wound around is greater than the number of turn of the armature winding that the stator poles away from excitation winding is wound around.
Particularly, have in a stator slot in described every three stator slots and be provided with excitation winding.
Particularly, described stator poles is often separated by two phases in series.
Particularly, described stator poles has 6 × and N number of, wherein N=1,2,3....
Beneficial effect: compared with identical with prior art each phase winding number of turn, the number of turn of the armature winding away from excitation winding is less than the number of turn of the armature winding of excitation winding both sides by the utility model, by the layout of this armature winding, make armature electric current more symmetrical, the Driving Torque of motor have also been obtained raising, the torque pulsation of motor reduces, and the performance of motor is improved.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the utility model armature winding series connection schematic diagram.
Embodiment
Below in conjunction with embodiment, illustrate the utility model further.
As shown in Figure 1-2, for three-phase 12/8 electric excitation biconvex electrode electric machine, a kind of three-phase double salient-pole electric machine armature winding structure, comprise excitation winding 1, armature winding 2 and stator poles 3, stator poles 3 is dentation, surround a circle by 12 toothed stator poles 3, be provided with stator slot 4 between adjacent stator pole 3, armature winding 2 passes through stator slot 4 around in stator poles 3; Often be separated by two stator slots 4 and be provided with an excitation winding 1, namely have in a stator slot 4 in every three stator slots 4 and be provided with excitation winding 1; The number of turn of armature winding 2 that the stator poles 3 of excitation winding 1 both sides is wound around is greater than the number of turn of the armature winding 2 that the stator poles 3 away from excitation winding 1 is wound around.
A, A1, A2, A3 A phase in series, B, B1, B2, B3 B phase in series, C, C1, C2, C3 C phase in series.
A, B, C threephase armature winding 2 number of turn is respectively Wa, Wb, Wc, the C phase winding number of turn away from excitation winding 1 is reduced, A, B phase keeps identical, i.e. Wa=Wb>Wc, and difference has the identical number of turn with each phase winding of double salient-pole electric machine of the prior art.When motor threephase armature winding 2 number of turn is not identical, be less than A, B two-phase armature supply of excitation winding 1 both sides away from the C phase armature supply of excitation winding 1 during stable state, when C phase armature winding 2 is reduced, the self-induction of C phase reduces, when motor powered works, the armature supply climbing of C phase improves, the current effective value of C phase improves, in this way, can make up the asymmetric impact brought of this body structure of part motor, and then the current-symmetrical degree of motor is improved, simultaneously, the Driving Torque of motor improves, and the performance of motor obtains larger improvement.
