Abstract
The utility model discloses a stator punching sheet adopting an embedded type structure, which comprises an internal stator and an external stator. The internal stator is arranged inside the external stator through the embedded type structure. The embedded type structure comprises a plurality of stator teeth arranged on the outer peripheral face of the internal stator and radial slots arranged on the inner peripheral face of the external stator. When used for motor production, the stator punching sheet adopting the above-mentioned technical scheme can first make windings sleeved inside the stator teeth of the internal stator. Then the external stator and the internal stator are laminated together with the windings through a pressing machine. The production efficiency is high.
Description
Technical field
The utility model relates to the motor stator field, specifically, specially refers to a kind of stator punching that adopts the inserted type structure.
Background technology
The general fluting of the stator punching of servomotor is more, causes the stator built-in line difficulty, and labour intensity is large, and efficiency is low, high to the requirement of operative employee's skills involved in the labour, is not easy to use automatic coil winding machine production, coil inserting apparatus rule even not easy to use.
In order to address the above problem, a kind of split-type piece lamination structure is arranged in prior art, this kind along the circumferential direction is divided into some pieces by stator punching, and each piece includes stator tooth for the coiling winding.The stator punching of this kind of structure has been exempted the stator built-in line operation when producing, and production efficiency is improved greatly.
But the defect of this kind of stator laminating structure is: during coiling, winding must reduce the production efficiency of coiling on piece, has improved the requirement to spooling equipment.Increased the amalgamation operation during assembling one, need to weld with laser welder, production cost has been increased more; The precision of assembling guarantees by frock, has improved the requirement to frock.
The utility model content
The purpose of this utility model is for above-mentioned the deficiencies in the prior art, provides a kind of simple in structure, and production process is easy, can be more suitable for the stator laminating structure of servomotor.
The technical problem that the utility model solves can realize by the following technical solutions:
A kind of stator punching that adopts the inserted type structure is characterized in that:
Described stator punching comprises internal stator and external stator, and described internal stator is installed on the inside of external stator by the inserted type structure, and described inserted type structure comprises the some stator tooths that are arranged at the internal stator outer peripheral face and the radial slot that is arranged at the external stator inner peripheral surface.
Adopt the stator punching of technical solutions of the utility model, can first winding be inserted in the stator tooth of internal stator being applied to when motor is produced, then with press, external stator is pressed to together with winding with internal stator, thereby complete the assembling of stator punching.
Further, the spacing of described some stator tooths equates and some stator tooths are distributed on the same level line.
Further, described radial slot is all identical with quantity and the size of stator tooth.
Further, the main body of described external stator and internal stator is loop configuration, and the cross section of described loop configuration is circle or rectangle.
Further, described stator tooth and radial slot are provided with insulation framework.
Compared with prior art, the beneficial effects of the utility model are as follows:
1) adopt the inserted type structure to connect, more simple than traditional split-type piece structure, packaging efficiency is higher, is more applicable for the production of servomotor.
2) easy to assembly, equipment, frock are not had to special requirement, production efficiency is high.
3) use skeleton to do slot liner and winding overhang insulation, reduced the height of winding overhang, reduced the enamelled wire consumption, reduced cost, reduced copper loss.
4) due to the change of insulation mode, and, without hand insertion, the insulation property of motor improve greatly.

The external stator schematic diagram of the stator punching that Fig. 3 is employing inserted type structure described in the utility model.
Number in the figure explanation: 100. external stator 110. radial slot 200. internal stator 210. stator tooths
Embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with embodiment, further set forth the utility model.
Referring to Fig. 1, Fig. 2 and Fig. 3, a kind of stator punching that adopts the inserted type structure described in the utility model, stator punching comprises external stator 100 and internal stator 200, described internal stator 200 is installed on the inside of external stator 100 by the inserted type structure, the inserted type structure comprises the some stator tooths 210 that are arranged at internal stator 200 outer peripheral faces and the radial slot 110 that is arranged at external stator 100 inner peripheral surfaces.Can first winding be inserted in the stator tooth 210 of internal stator 200 being applied to when motor is produced, then with press, external stator 100 be pressed to together with winding with internal stator 200, thereby complete the assembling of stator punching.
The spacing of described some stator tooths 210 equates, and some stator tooths 210 are distributed on the same level line, thus make whole stator punching stressed evenly.
Described radial slot 110 is all identical with quantity and the size of stator tooth 210, by adopting this kind of design, has guaranteed compactness and fastness that external stator 100 is connected with internal stator 200.
The main body of described external stator 100 and internal stator 200 is loop configuration, and the cross section of described loop configuration is circle or rectangle, thereby has promoted wide usage of the present utility model.
Described stator tooth 210 and radial slot 110 are provided with insulation framework, have reduced the height of winding overhang, have reduced the enamelled wire consumption, have reduced cost, have reduced copper loss.
Above demonstration and described basic principle of the present utility model and principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; that in above-described embodiment and specification, describes just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
