Abstract
A kind of improvement structure of split-type structure stator core, including cricoid stator core, annular iron core base, it is characterized in that cricoid stator core is formed by connecting by several pairs of segmental core units, each pair of segmental core unit includes negative segmental core unit, positive segmental core unit, the top of negative segmental core unit two sides is symmetrical arranged fluted, the two sides of negative segmental core unit lower part have been symmetrically arranged tongue-and-groove, the top of positive segmental core unit two sides is symmetrical arranged fluted, the two sides of positive segmental core unit lower part have been symmetrically arranged tenon, several pairs of segmental core units form cricoid stator core to head and the tail mortise-tenon joint, annular iron core base interference is inlayed into cricoid stator core inner hole.The utility model is compared with the prior art.It is interchangeable, conveniently with assembling, and be able to achieve split-type stator core and be connected with each other fastening sufficiently, point valve iron core unit is avoided the problem that because of the advantages of direction change generation cannot assemble.
Description
Technical field
The utility model relates to motor technologies.
Background technique
With the continuous promotion of manufacturing technology, motor manufacturing technology is also being constantly progressive with motor process technology.People couple
The requirements such as motor volume, weight, performance, service life are also higher and higher.Split-type stator core makes mould because its motor copper factor is high
Has size small, stock utilization is high, the low advantage of input cost, and many electrical machinery plants of attraction slowly developed implementation, example in recent years
As: technology disclosed in Chinese patent CN201710517833.9, single segmental core unit are respectively designed with tenon and tenon
Slot realizes that split-type stator core head and the tail are connected with each other the purpose of fastening.
Above-mentioned technology the problem is that: due to tenon and tongue-and-groove design in same segment core unit, coiling
It needs employee to distinguish the obverse and reverse position of iron core, just can guarantee and realize mortise-tenon joint between adjacent segmental core unit.But
If employee can not exchange, not note that will lead to adjacent segmental core unit tenon and tongue-and-groove does not correspond to generate not
Non-defective unit.Therefore what Chinese patent CN201710517833.9 was introduced is a kind of connection structure method of split-type inner-stator iron core,
But there is no the interchange issues for solving to assemble in production.
Summary of the invention
It is interchangeable, conveniently that the purpose of the present utility model is to provide a kind of assembly, and is able to achieve split-type stator core
It is connected with each other fastening sufficiently, avoids the problem that point valve iron core unit because the split-type structure that direction change, which generates, to assemble is fixed
The improvement structure of sub- iron core.
The utility model is realized in this way: including cricoid stator core, annular iron core base, special feature exists
It is formed by connecting in cricoid stator core by several pairs of segmental core units, each pair of segmental core unit includes negative segmental core list
Member, positive segmental core unit, the top of negative segmental core unit two sides are symmetrical arranged fluted, and groove is used for around stator coil,
The two sides of negative segmental core unit lower part have been symmetrically arranged tongue-and-groove, and negative segmental core unit laminates system by several punchings
It is symmetrical arranged at, the top of positive segmental core unit two sides fluted, groove is used under stator coil, positive segmental core unit
The two sides in portion have been symmetrically arranged tenon, and positive segmental core unit is stacked by several punchings, negative segmental core unit
The tongue-and-groove of side a pair of of segmental core unit of composition chimeric with the tenon of positive segmental core unit side, several pairs of segmental core lists
Member forms cricoid stator core to head and the tail mortise-tenon joint, and annular iron core base interference is inlayed into cricoid stator core inner hole
It is interior.
Beneficial effect
1, segmental core unit does not have point of front and back sides, therefore, the front and back sides interchangeable assembling of single segmental core unit；
2, fan-shaped stator core unit can be separated from stator core, both facilitate coiling, improve motor copper factor, and really
It is uniform to protect Distribution of Magnetic Field；
3, stock utilization can be improved, reduce motor manufacturing cost.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is the structural schematic diagram of segmental core unit pair.
Specific embodiment
The utility model is described in further detail now in conjunction with drawings and examples:
The utility model is realized in this way: including cricoid stator core a, annular iron core base 1, special feature
It is that cricoid stator core a is formed by connecting by several pairs of segmental core units, as shown in Fig. 2, each pair of segmental core unit includes
Negative segmental core unit 2, positive segmental core unit 3, the top of negative 2 two sides of segmental core unit is symmetrical arranged fluted 2a, recessed
Slot 2a is used for around stator coil, and the two sides of negative 2 lower part of segmental core unit have been symmetrically arranged tongue-and-groove 2b(shape such as: dovetail
Shape, arc-shaped etc.), negative segmental core unit 2 is stacked by several punchings, the top pair of positive 3 two sides of segmental core unit
Claiming to be arranged fluted 3a, the groove 3a of positive segmental core unit 3 is used for around stator coil, and the two of positive 3 lower part of segmental core unit
Side has been symmetrically arranged tenon 3b(shape such as: dovetail shaped, arc-shaped), positive segmental core unit 3 is folded by several punchings
It is pressed into, the tongue-and-groove 2b of negative 2 side of segmental core unit composition chimeric with the tenon 3b of positive 3 side of segmental core unit is a pair of to fan
Shape iron core unit, several pairs of segmental core units form cricoid stator core a, annular iron core base to head and the tail mortise-tenon joint
1 interference is inlayed into cricoid stator core a inner hole.
