Machine equipment has very big quantity required and very high prescription.
Existing motor, in order to mitigate the complete vehicle weight of electric automobile, its motor adopts aluminum alloy casing, due to aluminum
The coefficient of expansion be more than ferrum the coefficient of expansion, therefore, in motor operation, usually can make motor temperature raise, lead to stator ferrum
Core support expanded by heating.The coefficient of expansion due to support is more than the coefficient of expansion of stator core, in order to prevent in running
Stator is relatively rotated with support, needs support and stator are positioned.
Existing method using beating top wire hole on support, is positioned by jackscrew, this method not only increases mostly
Parts and processing, assembly process and difficulty, lose time, and so that production cost is increased, meanwhile, motor is long-time use after
Loosening the manifesting of jackscrew easily occurs, still can not tackle the problem at its root.
Utility model content
This utility model has designed and developed the location structure of a kind of motor stator and support, recessed using positioning convex and positioning
Groove cooperates, and stator and support are fixed, and can overcome the motor stator that temperature raises and causes in running
The problem relatively rotating with support.
This utility model provide technical scheme be：
A kind of motor stator and the location structure of support, including：
Rotor；
Stator punching, its periphery circle is provided with positioning convex, can position；
Support, it is internally provided with detent, can cooperate with described positioning convex, and it is fixed with stator circumference to realize
Position；
Wherein, the shape of described positioning convex and described detent includes：One of semicircle, trapezoidal, rectangle.
Preferably, described stator punching inner circumferential circle is equidistantly provided with multiple slot for windings.
Preferably, the shape of described positioning convex and described detent is using semicircle.
Preferably, upper end cover and bottom end cover are also included, it is separately positioned on the axial both sides of described stator.
Preferably, the upper setting notch at equal intervals of described stator punching periphery circle.
Preferably, described rotor is fixedly connected with axle.
Preferably, described stator punching adopts silicon steel material.
Beneficial effect described in the utility model：Stator punching periphery circle arranges bulge-structure, stator punching is folded
Press and form the stator with positioning convex, and the detent of stator and inboard wall of base is cooperated, realize the week of stator
To positioning, in stator punching lamination process, the bulge-structure on stator punching can play the effect of mistake proofing, rushes when making to laminate
The burr direction of piece is consistent.Using this kind of location structure, it is prevented from motor and raises with temperature in running and produce
Support expanded by heating, leads to stator to relatively rotate with support, can substitute intrinsic jackscrew positioning mode, simple to operate,
The saving time, improve the running efficiency of motor.This apparatus structure is simple, and positioning is reliable, easy to use, with low cost, is suitable for big
The popularization of scope and use.
Brief description
Fig. 1 is the structural representation of motor described in the utility model.
Fig. 2 is the structural representation of stator punching described in the utility model.

Specific embodiment
Below in conjunction with the accompanying drawings this utility model is described in further detail, to make those skilled in the art with reference to explanation
Book word can be implemented according to this.
As Figure 1-3, this utility model provides the location structure of a kind of motor stator and support, including support 30, its
For column structure, inner hollow, the inwall of support 30 is provided with the detent 31 of outer wall depression；Stator punching 21, its
For circular configuration, periphery circle is provided with positioning convex 211, multi-disc identical stator punching 21 is laminated on according to identical direction
Together, form stator 20, positioning convex 211 can be cooperated with the detent 31 on support 30, realizes the circumference of stator
Positioning.During stator punching 21 laminates, the direction that stator punching burr laminates can be made consistent, energy in lamination process
Enough play the effect of mistake proofing.
The inner circumferential circle of stator punching 21 is provided with multiple winding teeth 213 towards center of circle direction at equal intervals, adjacent
Form slot for winding between winding tooth, being capable of wound around coil.The periphery of stator punching 21 circle is provided with multiple interior at equal intervals
To groove 212, as a kind of preferably, this utility model select 6 in groove 212.
Upper end cover 10 and bottom end cover 50 are symmetricly set on the axial both sides of stator, and match with support 30；Rotor 60 energy
Enough and stator 20 cooperates and realizes electric energy and the mutual conversion of mechanical energy, mechanical energy and electric energy, simultaneously stator 20 and motor
Axle is fixedly connected.
The shape of positioning convex 211 of the present utility model and detent 31 includes in semicircle, trapezoidal, rectangle
