Abstract
The utility model discloses a stator for an elevator tractor. The stator comprises windings and an iron core, wherein the iron core comprises a fastening bolt (2), a bushing (3) and a plurality of sectorial stator teeth (1) which are closely arranged along the circumferential direction; and each stator tooth (1) is wound with an independent winding (4) and is fixedly fastened on the bushing (3) through the fastening bolt (2). Due to the structure, the whole stator is formed by combining a plurality of stator units, the length of the end part of an armature winding is greatly shortened, and the thickness of a motor body is reduced, so that the stator for the elevator tractor can adapt to the arrangement of machine roomless and small machine room elevators and reduces the material cost at the same time.
Description
Technical field
The utility model relates to the elevator technology field, specifically is a kind of stator that is applicable to the elevator traction machine of magneto.
Background technology
Along with elevator does not have the development of machine room and small room technology, be more little good more to the volume requirement of elevator traction machine, can reduce floor space like this, also be Bao Yuehao more particularly to the thickness requirement of traction machine.And that the approach that reduces volume only reduces the thickness of magneto body is the most economical and the most practical.Most employings is the cooperation of multipole multiple-grooved between the traction machine stator of prior art and the rotor; Stator armature adopts distributed winding to arrange; Like this stator armature end line length generally at 30cm between the 40cm; Thereby make stator armature bigger, make the technical development of magneto body thickness attenuation receive restriction to a certain extent in the interior occupation space.In addition, the distributed winding of multiple-grooved arranges that brought a lot of inconvenience to rule, the labour intensity of rule is big, production efficiency is low.Also have, the stator core of prior art is that the silicon steel sheet with full wafer is stamped to form, and the stator copper factor of this structure is on the low side, therefore, can cause the waste of silicon steel sheet bigger, and the while volume of motor is also bigger.
The utility model content
The utility model technical problem to be solved is; Provide a kind of and can make the attenuation of motor body thickness; Thereby reduce motor volume, thereby can be used to not have the layout of machine room and small room elevator, the stator of the elevator traction machine of reduced material cost simultaneously, enhancing productivity.
For solving the problems of the technologies described above; The stator of the elevator traction machine that the utility model provides; Comprise winding and iron core; Described iron core comprises fastening bolt, lining and a plurality of along the circumferential direction compact arranged fan-shaped stator tooth, all be wound with winding on described each stator tooth, and each stator tooth is fixed tightly on the lining through fastening bolt all.
After adopting above structure, the utility model compared with prior art has the following advantages: because stator core is made up of a plurality of fan-shaped stator tooths; All be wound with winding on each stator tooth, in other words, whole stator is combined by a plurality of stator units; Be monodentate unicoil stand alone type winding, the length of armature end-connections is shortened greatly, shortened the thickness of motor body; Make its layout that can adapt to no machine room and small room elevator, also reduced material cost simultaneously; In addition, this stator tooth of forming by a plurality of unit tooth, the production efficiency of its coiling can be improved, thereby realizes bigger copper factor.
As improvement, between the axis hole of described clamping bolt and stator tooth for closely cooperating.Cooperating between the axis hole of described clamping bolt and stator tooth adopted H8/f7.After adopting this closely cooperating; Make clamping bolt and stator tooth close-fitting on the one hand diametrically; On axial end, also make clamping bolt and stator tooth close-fitting on the other hand; Thereby guaranteed closely cooperating between stator tooth and the lining effectively, thereby received the influence of electromagnetic force when avoiding load running and produce vibration.
As further improvement, the winding slot on the described stator tooth is a straight trough, and promptly the bottom land of winding slot is parallel at length direction with stator tooth.After adopting this structure, cancelled the flume structure of complicacy in the prior art, made simplified processing technology, helped enhancing productivity.
As further improving, the number of degrees of the segment angle of described stator tooth are 360 ° of numbers divided by stator tooth.After adopting this relational expression, the faying face of adjacent two stator tooths can more be fitted.

Wherein: 1, stator tooth; 2, fastening bolt; 3, lining; 4, winding; 5, winding slot; A, segment angle.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is done explanation in further detail.
Structural representation by the stator of the utility model elevator traction machine of Fig. 1～shown in Figure 3 can be known; It comprises winding and iron core; Described iron core comprises fastening bolt 2, lining 3 and a plurality of along the circumferential direction compact arranged fan-shaped stator tooth 1; All be wound with independently winding 4 on described each stator tooth 1, and each stator tooth 1 is fixed tightly on the lining 3 through fastening bolt 2 all.This monodentate unicoil stand alone type winding has changed traditional wire insertion technology, and directly around to stator core, copper factor can reach 80% with line.
Between the axis hole of described fastening bolt 2 and stator tooth 1 for closely cooperating.In the present embodiment, this cooperates employing H8/f7.
The number of degrees of the segment angle A of described stator tooth 1 are 360 ° of numbers divided by stator tooth 1.Each stator tooth 1 leans on the angle of segment angle to cooperate splicing on the lining 3 of stator; Be placed on the base together; Be limited in each stator tooth in the endoporus of the core that rises with the core that rises, ringfeder presses down the core dimensional contraction that rises is close to circle in all stator tooths on the lining of stator, and fixes with fastening bolt again; Take off rise core and ringfeder, the roundness tolerance after splicing is accomplished like this can reach 0.08mm.
