Description
Technical field
The utility model is related to a kind of stator core, belongs to power equipment accessory technical field.
Background technology
Motor is widely used in household electrical appliances and industrial circle as the core drive of modern society.Stator slice structure is in electricity
Using more in machine, there is silicon steel sheet utilization rate height, small volume, efficiency high.At present, motor conventional in prior art
Exist.Heat sinking function is poor, be not easy positioning, the problems such as easily slide.The other connection side between each stator tooth of existing stator core
Formula also affects the stability and service life of stator core.
Utility model content
The utility model provides a kind of stator core, solves in prior art that stator core heat sinking function is poor, is difficult calmly
Position, the problem that stability is poor, service life is short.
The technical solution adopted in the utility model is：
A kind of stator core, by the stator tooth connection of 8 units ring-type is constituted, and yoke portion 2, tooth is contained on the stator tooth 1
Portion 3, crown 4, key teeth 5, air vent 6, convex fitting portion 7, recessed fitting portion 8, locating slot 9, welding groove 10；Stator tooth 1 is by plural number
Individual core lamination stack closed assembly is combined；In the bottom of stator tooth 1, teeth portion 3 is in the upper surface in yoke portion 2, teeth portion 3 in the yoke portion 2
It is above crown 4, crown 4 is above key teeth 5；The number of the air vent 6 is one, in the teeth portion 3 of stator tooth 1；Institute
State stator tooth 1 to be connected with each other by convex fitting portion 6 and recessed fitting portion 7；Locating slot 9, welding groove after the stator tooth connection of unit
10 along stator core body outer wall circumference be distributed.
There is one layer of antirust oil reservoir outside the stator core.
The utility model beneficial effect：
The stator core that the utility model is provided, in stator tooth air vent is provided with, and plays thermolysis, prevents iron core local
Coil near overheated easily burns；Constituted using multiple stator tooths, make adjacent two fixed by recessed fitting portion and convex fitting portion
Sub- tooth connection, expands its bonded area, improves the stability of combination, expands groove area；Iron core be provided with locating slot and
Welding groove so that the iron core accurate positioning, it is stable.The utility model simple structure, it is convenient and practical.

Specific embodiment
As shown in Figure 1-2 a kind of iron core, a kind of stator core, by 8 unit stator tooth connections ring-type, the stator are constituted
Contain yoke portion 2, teeth portion 3, crown 4, key teeth 5, air vent 6, convex fitting portion 7, recessed fitting portion 8, locating slot 9, welding groove on tooth 1
10；Stator tooth 1 is combined by a plurality of core lamination stack closed assemblies；In the bottom of stator tooth 1, teeth portion 3 is in yoke in the yoke portion 2
The upper surface in portion 2, teeth portion 3 is above crown 4, and crown 4 is above key teeth 5；The number of the air vent 6 is one, stator tooth 1
Teeth portion on；The stator tooth 1 is connected with each other by convex fitting portion 6 and recessed fitting portion 7；Positioning after the stator tooth connection of unit
Groove 9, welding groove 10 are distributed along the outer wall circumference of stator core body.
There is one layer of antirust oil reservoir outside the stator core.
Although the utility model is disclosed as above with preferred embodiment, it is not limited to the utility model, any
Person skilled in the art, in without departing from spirit and scope of the present utility model, can do various changes and modification, therefore this
The protection domain of utility model should be with what claims were defined.
Claims (2)
