Abstract
The utility model discloses a spliced motor stator core, which is characterized by comprising a plurality of iron core blocks (1) separated along peripheral direction and extended along radial direction, wherein the iron core block (1) comprises an arc-shaped back iron (5) and a wrapping post (4) arranged at an inner side of the back iron (5), one end of the back iron (5) is provided with a boss (2), and the other end is provided with a groove (3) which mates with the boss (2). In the utility model, a plurality of iron core blocks are spliced to be the stator core, each iron core block carries out sheet-punching as an independent unit to benefit layout of the punched sheet, therefore, utilization rate of the material is improved, and 20% of material is saved compared with that of the traditional sheet-punching mode. Besides, straight coiling method can be applied to an individual iron core, coiling is more convenient and reliable, substantially improving production efficiency. At the same time, coiling quality is improved, and one-time quality rate is increased.
Description
Technical field
The utility model relates to a kind of stator component of direct current machine, particularly a kind of spliced motor stator core.
Background technology
The stator core of conventional direct current machine is a completely circular structure, adopts the mode of whole punching, makes that the utilance of silicon steel sheet is lower; And the winding mode of conventional completely circular structure stator core is interior around formula, and production efficiency is not high, and the disposable qualification rate of coiling is lower.
The utility model content
The purpose of this utility model is, a kind of spliced motor stator core is provided.The utility model can not only be saved material, can also enhance productivity and the qualification rate of disposable production.
The technical solution of the utility model: a kind of spliced motor stator core, it is characterized in that: comprise the some iron core pieces that radially extend that along the circumferential direction separate, the iron core piece comprises the back iron of circular arc and is arranged on the wrapping post of back iron inboard, back iron one end is provided with boss, and the other end is provided with the groove that cooperates with boss.
In the aforesaid spliced motor stator core, the piece number of described iron core piece is 2～12.
In the aforesaid spliced motor stator core, the piece number of described iron core piece is 4.
In the aforesaid spliced motor stator core, the back iron inboard of described iron core piece is provided with 3 wrapping posts.
Compared with prior art, the utility model adopts some iron core pieces is spliced to form stator core, every iron core piece as one independently the unit carry out punching, the discharge that helps punching, improved the utilance of material, compared with traditional punching mode, material can save 20%; In addition, independent iron core piece can adopt the winding mode of directly-wound, and it is convenient, reliable to wind the line, and has improved production efficiency greatly, can also improve the quality of coiling simultaneously, improves disposable qualification rate.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the structural representation of the utility model iron core piece.
Being labeled as in the accompanying drawing: 1-iron core piece, 2-boss, 3-groove, 4-wrapping post, 5-back iron.
Embodiment
Below in conjunction with drawings and Examples the utility model is further described, but not as the foundation to the utility model restriction.
Embodiment.A kind of spliced motor stator core, constitute as illustrated in fig. 1 and 2, it is characterized in that: comprise the some iron core pieces 1 that radially extend that along the circumferential direction separate, iron core piece 1 comprises the back iron 5 of circular arc and is arranged on the wrapping post 4 of back iron 5 inboards, back iron 5 one ends are provided with boss 2, and the other end is provided with the groove 3 that cooperates with boss 2.
Reasonable is that the piece number of described iron core piece 1 is 2～12.
Be more preferably, the piece number of described iron core piece 1 is 4; The back iron inboard of described each iron core piece 1 is provided with 3 wrapping posts 4.
The utility model will evenly be divided into 4 iron core pieces with the stator core of full circle, and every iron core piece has 3 wrapping posts, and the wrapping post of each iron core piece winds the line, and the iron core piece that will wind line again carries out head and the tail and is spliced to form a stator.By stator skeleton stator is compressed installation at last.
