Embodiment
It should be noted that in the case where not conflicting, the feature in embodiment and embodiment in the present invention can phase
Mutually combination.Describe the present invention in detail below with reference to the accompanying drawings and in conjunction with the embodiments.
In order that those skilled in the art more fully understand the present invention program, below in conjunction with the embodiment of the present invention
Accompanying drawing, the technical scheme in the embodiment of the present invention is clearly and completely described, it is clear that described embodiment is only
The embodiment of a part of the invention, rather than whole embodiments.Based on the embodiment in the present invention, ordinary skill people
The every other embodiment that member is obtained under the premise of creative work is not made, it should all belong to the model that the present invention protects
Enclose.
It should be noted that term " first " in description and claims of this specification and above-mentioned accompanying drawing, "
Two " etc. be for distinguishing similar object, without for describing specific order or precedence.It should be appreciated that so use
Term can exchange in the appropriate case, so as to embodiments of the invention described herein.In addition, term " comprising " and " tool
Have " and their any deformation, it is intended that cover it is non-exclusive include, for example, containing series of steps or unit
Process, method, system, product or equipment are not necessarily limited to those steps clearly listed or unit, but may include without clear
It is listing to Chu or for the intrinsic other steps of these processes, method, product or equipment or unit.
In the present invention, based on winding sequence of the prior art, by the more grooves of 3 phase, 2 pole 24 of the prior art
Technical scheme stator inductance surveyed, find A, B, C three pole reactors are sequentially reduced, and A compares substantially big 5%, the B of B phases
Substantially big by 3% compared to C phases, three pole reactor maximum deviation is up to 8%.
By the research repeatedly and test to three phase electric machine shortcoming of the prior art, discovery causes three-phase in the prior art
The main reason for motor defect is：A phase windings elder generation rule, during embedding complete and then embedding B phase windings, A phase windings have to B phase windings
Certain interference, B phase windings are caused can not to be all pressed onto trench bottom.Similarly, when embedding C phase windings, A phases, B phase windings are all to C
Phase winding has certain interference.Which results in A, B, C three pole reactors are sequentially reduced, and the increase of three pole reactor degree of asymmetry.Generally, it is right
This inductance difference can be improved by automated machine shaping in small machine.But for Large-power High-Speed motor, due to motor
And radical of having mercy on is more, the reasons such as stator core is larger, automated machine coiling, shaping can not be used.
Therefore, want to improve motor inductances by adjusting the groove depth between different phases in the inventive solutions
Symmetry.
