Abstract
The utility model provides a structure of a motor stator. Connection parts among stator tooth parts in the prior art are removed, thereby forming narrow middle parts. The middle parts absorb forces generated by interference in a fixed part iron core, thereby preventing the deformation of a wheel-shaped stator tooth part structure. In the structure of the motor stator in the utility model, conical tooth parts are arranged in a manner of facing two sides of an inner peripheral position of all the stator tooth parts respectively. And among the neighboring conical tooth parts, no connection part exists, but the narrow middle parts used for bearing the forces generated by the interference in the fixed part iron core are formed.
Description
Technical field
The utility model relates to the stator structure of motor; Be mainly; With being installed in coupling part (generally being referred to as bridge joint) the length vanishing on the circumferencial direction between inboard each stator teeth of colyliform stator tooth wheel body of colyliform fixed part iron core; And utilize connecting of adjacent round conial tooth part formation than part between detail; Bear the perturbed force that is produced when colyliform stator tooth wheel body is installed in this way in the fixed part iron core, and realize the colyliform stator tooth wheel body simple installationization in the fixed part iron core with this new mode of ameliorating.
Background technology
The motor stator structure of the same type that was in the past adopted is generally like the structure among Fig. 3.Just shown a part among Fig. 3, through being pressed into process Installation colyliform stator tooth wheel body 2, the outer peripheral face 3a of each stator teeth 3 of this colyliform stator tooth wheel body 2 links to each other with the inner peripheral surface 1a of fixed part iron core 1 again in the inboard of colyliform fixed part iron core 1.Length on above-mentioned each stator teeth 3 circumferencial direction C is the represented zone of symbol A; Along connecting each stator teeth 3; The zone that the length of bridging part 4 circumferencial direction C between 3 is represented for symbol B; Length along these bridging part 4 radial directions is the represented zone of symbol D, and is as shown in the figure, and these length all are appointments.Between each stator teeth 3,3, form tooth portion groove 5 simultaneously.
Motor stator in the past adopts said structure, thereby has following problem.Between each stator teeth; Have the coupling part that possesses designated length on the radial direction, same in a circumferential direction existence possesses the coupling part of designated length, thereby forms bridging part; Therefore when being pressed into colyliform stator tooth wheel body in the fixed part iron core; Each stator teeth be difficult to absorb that radial direction etc. produced more energetically, the perturbed force between the fixed part iron core just makes colyliform stator tooth wheel body after the assembling distortion etc. occur and finally causes its bad characteristic.
The utility model content
The utility model purpose: the utility model aims at solving above-mentioned problem, is purpose with the motor stator that following structure is provided.With being installed in coupling part (generally being referred to as bridge joint) the length vanishing on the circumferencial direction between inboard each stator teeth of colyliform stator tooth wheel body of colyliform fixed part iron core; And utilize connecting of adjacent round conial tooth part formation than part between detail; Bear the perturbed force that is produced when colyliform stator tooth wheel body is installed by this way in the fixed part iron core, and realize the colyliform stator tooth wheel body simple installationization in the fixed part iron core with this new mode of ameliorating.
Technical scheme: the motor stator in the utility model is by colyliform fixed part iron core; Be installed in said fixing portion iron core inboard is integrally formed the formula structure by a plurality of stator teeths colyliform stator tooth wheel body; Thereby the tooth portion groove that each stator teeth outer peripheral face is connected and is forming between each stator teeth with fixed part iron core inner peripheral surface; The stator coil that is installed on above-mentioned each tooth portion groove constitutes; In this motor stator structure; Possess the paired round conial tooth part with cone part that in each stator teeth both sides, all positions and configuration are along the circumferential direction arranged, the circumferencial direction coupling part length vanishing between adjacent stators tooth portion circle conial tooth part is integrally formed built up structure through thinner mid portion; Simultaneously, above-mentioned cone partly forms tooth portion groove.
Beneficial effect:, therefore can obtain following effect because the structure of the motor stator in the utility model has adopted above structure.Coupling part in the past no longer is set between each stator teeth of colyliform stator tooth wheel body; Each the circle conial tooth part that possesses the cone part directly is connected to form thinner mid portion; Thereby elasticity of utilizing this thin part absorbs colyliform stator tooth wheel body is pressed into the perturbed force that is produced to the fixed part iron core process; Prevent stator deformability bad characteristic etc., implementation structure is stable.

Embodiment
Below, will describe together with the suitable application form of accompanying drawing this motor stator structure utility model.In addition, will utilize the prosign mark to describe with the identical or equal part of example in the past.In Fig. 1 and Fig. 3, the part shown in the symbol 1 is the fixed part iron core of being made up of colyliform cascade type structure, adopts to be pressed into the inboard that colyliform stator tooth wheel body 2 that technology etc. will possess a plurality of stator teeths 3 is installed in this fixed part iron core 1.
Each stator teeth 3 outer peripheral face 3a of above-mentioned colyliform stator tooth wheel body 2 are connected with the inner peripheral surface 1a of fixed part iron core 1, and stator coil 10 is installed on this stator teeth 3, and this stator coil 10 is positioned in the tooth portion groove 5 between each stator teeth 3,3.
In the bottom of above-mentioned each stator teeth 3 on all positions 11, along the circumferential direction layout circle conical section 12 is positioned at the paired cone tooth portion 13 of tooth portion groove 5 towards the inboard.Length range on this stator teeth 3 circumferencial direction C is shown in the symbol A that has comprised each circle conial tooth part 13,13.Simultaneously, the length of the circumferencial direction C coupling part B that each circle conial tooth part of adjacent stators tooth portion 3,3 is 13,13 is zero and carries out the integral type connection, forms the bridging part complete obiteration through this coupling part B, is nought state.Promptly shown in the enlarged drawing of Fig. 2; The B of coupling part in the past that shows among Fig. 3 is banned fully; Each circle conial tooth part 13 directly links to each other, and form be positioned between each circle conial tooth part 13,13, be equivalent to coupling part B in the past, more than other parts tiny than part between detail 20.
Adopt above structure; Above-mentioned colyliform stator teeth 2 is being pressed in the process that is mounted in the fixed part iron core 1; When the perturbed force of 1 of fixed part iron core was applied to each stator teeth 3, the unisexuality effect that the thin part 20 in centre between each circle conial tooth part 13,13 is produced can absorb and bear this perturbed force; Prevent that distortion (permanent stress distortion etc.) from appearring in colyliform stator teeth 2, prevent that changing or deterioration from appearring in characteristic.
