Abstract
The invention relates to the technical field of motors, in particular to a motor. The motor comprises a stator assembly, end covers, protrusions and grooves. The protrusions are arranged on one of the stator assembly and the end covers, and the grooves are formed in the other of the stator assembly and the end covers. The stator assembly and the end covers are matched through fool-proof structures formed by inserting the protrusions and the grooves. The fool-proof structures formed by the protrusions and the grooves are arranged between the stator assembly and the end covers, and the problem of rework caused by wrong mounting of an end cover in the assembly process can be avoided. Meanwhile, due to the fact that the protrusions and the grooves are arranged, the contact area between the end covers and the stator assembly is increased, heat of the stator assembly can be transferred to the end covers through the cooperation of the protrusions and the end covers and finally emitted out through the end covers, and the heat radiation efficiency of the stator assembly is improved.

Specific embodiment
Technical scheme is further illustrated below in conjunction with the accompanying drawings and by specific embodiment.
As shown in Figures 3 to 6, present embodiments provide for a kind of motor, the motor includes stator module 1 and end cap 2, with
And raised 3 and groove 4.Raised 3 are arranged on one of stator module 1 and end cap 2, and groove 4 is arranged on another.
By being plugged with the error-proof structure for being formed carries out from raised 3 and groove 4 between stator module 1 and end cap 2.
In the present embodiment, the fool proof by being provided with raised 3 and the formation of groove 4 between stator module 1 and end cap 2 is tied
Structure, can prevent end cap 2 in assembling process, because of the wrongly installed rework problems for causing.Simultaneously as raised 3 and the setting of groove 4
Put, the contact area between end cap 2 and stator module 1 is increased, the heat of stator module 1 can be made by raised 3 and groove 4
Cooperation be transferred on end cap 2, finally by end cap 2, heat is distributed, improves the radiating efficiency of stator module 1.
The specific version of error-proof structure, motor includes multiple raised 3, and divides in one-to-one corresponding with multiple raised 3
The groove 4 of cloth, multiple raised 3 with respect to stator module 1 or end cap 2 center in non-centrosymmetry be distributed.Correspond herein
Distribution is referred to：Projection 3 and 4 quantity of groove and shape are in one-to-one form, that is to say, that each raised 3 equal energy insertion
In one groove 4 corresponding thereto.
Multiple raised 3 structures are identical, and multiple raised 3 heterogeneous are distributed on stator module 1 or end cap 2.Pass through
Multiple raised 3 heterogeneous be distributed on stator module 1, thus, it is possible to guarantee between stator module 1 and end cap 2 only one kind
Fit form, thus prevent in the assembling process of end cap 2, wrongly installed problem occurs.
For convenience of description, be distribution situation that raised 3 and groove 4 is limited with raised 3 facilities herein, because
Projection 3 and groove 4 are corresponding distributions, and both cooperate.As long as the position of one of them determines, another
Position should also be determination.Such as, raised 3 are arranged on stator module 1, and corresponding groove 4 is provided in end cap 2 certainly
On, raised 3 is non-equally distributed, and groove 4 is also non-uniform Distribution accordingly.
Specifically, the projection 3 of multiple non-uniform Distribution is provided with stator module 1, is provided with accordingly many on end cap 2
The groove 4 of individual non-uniform Distribution.
In the present embodiment, the form that another projection 3 and groove 4 are arranged is additionally provided.At least include two kinds of knots
The projection 3 of structure pattern.Structural style herein refers to size, shape etc..Due to the difference of the structural style between projection 3,
Multiple raised 3 can be uniformly distributed, it is also possible to uneven distribution.
Specifically, with reference to Fig. 5, Fig. 6, the axial end of stator module 1 has along the circumferential direction been uniformly arranged 5 projections 3, end
Lid 2 arranges fluted 4 in corresponding position.The cross section of above-mentioned 5 projections 3 is all in sector, but each not phase of raised 3 size
With, the form that the projection 3 of this kind of version and groove 4 coordinate, in assembling process, only a kind of fit form, will not go out
Existing anti-loaded situation.Except above-mentioned situation, in 5 projections 3, wherein 4 circular protrusions 3, one is square protruding 3, this kind of convex
The form of 3 and the cooperation of groove 4 is played, is not in equally anti-loaded situation.
After projection 3 and groove 4 are mutually inserted, there are two kinds of fit forms：
It is fitted close between raised 3 and groove 4, this kind of fit form can be improved between end cap 2 and stator module 1 and be coordinated
Compactness.
Raised 3 and after groove 4 plugs, there is gap between the two, this kind of raised 3 and groove 4 fit form, permissible
The grafting being easy between raised 3 and groove 4.Projection 3 and the specific fit form of groove 4, can be selected according to actual needs
Select.
Raised 3 cross section is circular, fan-shaped or triangle, and corresponding groove 4 also has corresponding shape, certainly convex
3 and groove 4 is played, is also not excluded for that there is other structures form.
End cap 2 includes drive end bearing bracket and rear end cap, is at least provided with error-proof structure between rear end cap and stator module 1, wherein,
Raised 3 are arranged on stator module 1, and groove 4 is arranged on rear end cap.In this embodiment, it is preferred that in rear end cap and calmly
Between sub-component 1, error-proof structure is set, because being provided with encoder 5 on rear end cap, the position of encoder 5 is to determine, needs
Prevent rear end cap from anti-loaded problem occur.
Motor also includes screw, is fastened by screw between end cap 2 and motor case 6.End cap 2 is by screw and motor machine
Shell 6 is fixed so that projection 3 can limit stator module 1 with the cooperation of groove 4 and rotate with respect to motor case 6, especially for
Heavy-duty motor, the structure income is bigger, the reliability of lifting motor.
The know-why of the present invention is described above in association with specific embodiment.These descriptions are intended merely to explain the present invention's
Principle, and limiting the scope of the invention can not be construed to by any way.Based on explanation herein, the technology of this area
Personnel associate other specific embodiments of the present invention by need not paying performing creative labour, these modes fall within
Within protection scope of the present invention.
