Description
Technical field
The present invention relates to technical field of motors, and in particular to a kind of stator core construction and a kind of motor.
Background technology
Stator core is the important component of motor, and stator core generally by stator yoke and is formed in stator yoke
The stator teeth composition of circumference.With market development, the requirement for the high-effect low power consuming of motor is also stepped up, in order to realize
This purpose, with reference to Fig. 3, from design of electrical motor angle for, reduction the close iron loss that can effectively reduce of stator magnet reach reduction energy
The purpose of consumption, so as to improve the efficiency of motor.And on the premise of motor block dimension is basically unchanged, increase the axle of stator core
Be then to length effective reduction stator magnet it is close have individual effective means.The stator core of prior art is by the way of punching is stacked
Constitute, to improve electric efficiency, those skilled in the art realize often through the mode of the overall length for increasing stator core
The close purpose of stator core magnetic is reduced, but following defect is then easily produced after stator core length increase：1st, due to stator iron
The length of core is long, and the heat produced in the motor course of work in stator core is not easy export, therefore causes motor radiating to be imitated
Fruit is deteriorated；2nd, rotor is rotated around a fixed rotating shaft in the ideal situation, and in practical work process, because motor is unavoidable
Shake, therefore also unavoidable produced because of vibrations tilts and deviates ideal position for the rotating shaft, also can which results in rotor
Produce lateral deviation.When rotor deviate constant preferable rotating shaft angle, rotor and stator teeth gap it is constant on the premise of, stator core
Length is longer, and also easier and stator core the stator teeth of rotor, which is hung, to be rubbed, therefore longer stator core will cause frequency
Numerous sweeps thorax phenomenon.
The content of the invention
Therefore, the technical problem to be solved in the present invention be to overcome in the prior art long stator iron core structure be easily caused electricity
Machine radiating effect is deteriorated, and frequently sweeps the technological deficiency of thorax, so that it is good to provide a kind of motor radiating effect, it is not easy to sweep thorax
Stator core construction and motor.
In order to solve the above technical problems, the present invention provides a kind of stator core construction, including stator yoke, and described fixed
Multigroup stator teeth of the inner periphery array arrangement in sub- yoke portion, the length direction of the stator teeth is along the stator yoke
It is axially extending, the length being shorter in length than with the stator yoke of at least one set of stator teeth.
In said stator core structure, stator teeth described in every group is axially isometric.
In said stator core structure, the stator yoke is axially isometric.
In said stator core structure, cylindrical a diameter of 101.09-101.14mm where the stator yoke；It is described fixed
A diameter of 53.1-53.6mm of inner circle where sub- teeth portion.
Some detents, the detent are provided with said stator core structure, on the stator yoke is cylindrical
Groove top radially to the cylindrical size of the stator yoke of opposite side to cut root size, the root size of cutting is
100.23-100.28mm。
In said stator core structure, the detent radially corresponds setting with stator teeth described in every group.
In said stator core structure, the stator teeth is nine groups.
In said stator core structure, constituted if the stator core construction stacks fixation by dried layer punching sheet unit.
The present invention also provides a kind of motor, including above-mentioned stator core construction.
Technical solution of the present invention, has the following advantages that：
1. in the stator core construction that the present invention is provided, stator teeth is set to be shorter than the length of stator yoke, in stator
In the case that teeth portion length is constant, only increasing the length of stator yoke contributes to the magnetic for reducing stator core close, so as to reduce electricity
Iron loss in machine running, improves motor operation efficiency.
2. in said stator core structure, due to reduce magnetic it is close while, the physical length of stator teeth does not increase
Plus, therefore the stator core construction of the present embodiment will not be made easily to occur the situation for sweeping thorax when in use.
3. in said stator core structure, because the length of stator teeth is constant, the length increase of stator yoke, and due to
Produced by heat is the part being engaged as rotor and stator teeth, therefore the stator core construction of the present embodiment is not interfered with
Radiating effect.
4. in said stator core structure, with being reduced in the prior art using overall increase stator teeth and stator yoke
The close mode of magnetic is compared, additionally it is possible to obvious to save punching material, so as to play cost-effective effect.

Embodiment 1
Technical scheme is clearly and completely described below in conjunction with accompanying drawing.
With reference to Fig. 1 and 2, the present embodiment provides a kind of stator core construction, is widely used in motor, including circumferentially battle array
Arrange multigroup stator teeth 2 of arrangement, and the stator yoke 1 that stator teeth 2 is connected, the length direction edge of stator teeth 2
The axially extending of stator yoke 1, wherein, the length of the length stator yoke 1 of the stator teeth 2.Stator yoke 1 and stator
Teeth portion 2 stacks fixed punching sheet unit by multi-disc and constituted, formed on punching sheet unit stator teeth unit, stator yoke unit or
Stator yoke unit is only formed, stacks after fixing to form the stator teeth 1 and stator teeth 2.Be present in one end or
Stator yoke unit is only formed in the punching sheet unit at two ends, so that the length of stator yoke 1 is longer than stator teeth 2
Length.Every group of stator teeth 2 is axially isometric；And stator yoke 1 is axially isometric.The group number of stator teeth 2 is nine groups.
