Abstract
The utility model relates to an improved internal structure of a motor, particularly to a block-type motor stator lamination. The utility model adopts the following technical scheme: the block-type motor stator lamination comprises yoke parts and a tooth parts, and is characterized in that each yoke part is divided into at least two parts in the circumferential direction. Specifically, the block-type motor stator lamination can be designed as I-shaped structures formed by each independent part of each yoke part and teeth inside each tooth part, and the two end faces of each yoke part of each the I-shaped structure adopt radial straight edges along the outer margin of each yoke part. By virtue of the structure, the whole lamination comprises the minimal units which are conveniently processed, moreover, and the I-shaped structures can be reasonably laid on a strip-shaped sheet during the processing, thereby achieving the purpose of reducing the cost to the utmost extent on the basis of easy processing of the motor stator lamination.
Description
Technical field
The utility model relates to the internal structure of motor and improves specifically a kind of assembled piece type motor stator punching.
Background technology
The manufacture method of traditional motor stator punching all is a drawing, stator core is by the riveting moulding that superposes, its shortcoming is that the blanking of stator core part in the process of drawing has just become waste material, caused the waste of material, the iron core part also needs other permanent-magnet materials to fill, need special-purpose coil winding machine in the coiling process and just can finish, and threading speed is slow, inefficiency.
Summary of the invention
For solving the problems of the technologies described above, the utility model provides a kind of assembled piece type motor stator punching, adopts the form of punching piece to make motor stator, and need not make stator core separately, has saved material, has improved production efficiency.
The technical solution of the utility model comprises its yoke portion and tooth portion, it is characterized in that: its yoke portion is along circumferentially being divided into two parts at least, and the tooth of position correspondence is structure as a whole with corresponding yoke portion.This structure can it constitutes according to the design rational in infrastructure of different punchings, thereby realizes reasonable cloth, the purpose that reduces waste material, reduces cost.
Specifically, the tooth that the utility model can be designed in each independent parts of yoke portion and the tooth portion constitutes worker's shape structure, and two end faces of each worker's shape structure yoke portion are along its outer rim straight flange radially.This structure makes whole punching be made up of the minimum unit of being convenient to process, and, the processing of this worker's shape structure can be on the bar shaped sheet material reasonable cloth, thereby on the basis that guarantees handling ease, realize the purpose that reduces cost to greatest extent.
In said structure, can adopt multiple mode that adjacent two worker's shape Stability Analysis of Structures are connected, comparatively simply be following mode: the groove that has projection on two end faces of each worker's shape structure yoke portion respectively and adapt to projection, the projection and the groove of adjacent two worker's shape structures combine.
The utility model has adopted silicon steel sheet has been struck out a plurality of splitting modes making motor stator punchings that include the stator punching piece of stator teeth and yoke portion, and wind the line at stator teeth, therefore all stator punching pieces have replaced stator core, and need not make stator core in addition, material and copper cash have greatly been saved, it is convenient to wind the line before combination, is fit to mechanized operation, has improved production efficiency.
Description of drawings
Fig. 1 adds the cloth figure in man-hour for embodiment worker's shape structure;
Fig. 2 is the structure chart of embodiment user mode;
Fig. 3 is the figure of worker's shape structure;
Wherein, 1, worker's shape structure, 2, groove, 3, yoke portion, 4, projection, 5, tooth portion.
Embodiment
As shown in the figure, present embodiment comprises yoke portion 3 and tooth portion 5, and tooth portion 5 is made up of one group of tooth.Yoke portion 3 circumferentially is divided into a plurality of separate parts along it, and each part and a tooth constitute worker's shape structure 1.The end face of yoke portion 3 each independent parts is along its outer marginal circumference straight line radially, the groove 2 that has projection 4 on the both ends of the surface respectively and adapt with projection 4.The projection 4 of adjacent two worker's shape structures cooperates with groove 2, and it is interconnected.Interval between worker's shape structure 1 tooth constitutes the gap between each tooth of present embodiment.
