Abstract
The utility model discloses a stator comprising an iron core. The iron core comprises a plurality of independent iron core sub-blocks. The iron core sub-blocks are kept together through an insulation sleeve. A machine casing is arranged outside the insulation sleeve. According to the stator of the utility model, a converse chamfer is arranged on the bottom end of the insulation sleeve. After the converse chamfer is arranged, the stator can enter the inner portion of the machine casing very smoothly. The disability rate can drop to 0.2%, and the success rate is substantially raised. The stator of the utility model is simple in structure and high in safety performance. The stator is suitable for being widely promoted.
Description
Technical field
The utility model relates to a kind of motor stator, is specifically related to a kind of chamfering stator.
Background technology
stator is the actionless part of motor, stator is by stator core, stator winding and several three parts form, the Main Function of stator is to produce rotating magnetic field, very simple of the structure of stator, usually by iron core, coil, skeleton, lead-in wire, extension spring forms, stator has two kinds of modes of connection, a kind of is 4 line formulas, the rotor series winding is connected between 2 stator winding, a kind of is 2 line formulas, connect with the rotor series winding again after connecting with the rotor series winding again after 2 stator winding connect, (2 lead-in wires at 4 line formula diagonal angles are connected together), two kinds of mode of connection differences, but can be general.
But while at present stator being put into casing, stator is not easy to enter casing, often causes scrapping of stator and casing, and scrappage reaches 5%, causes high cost, is unfavorable for large-scale production.
Be 200520026683.4 as application number, the applying date is 2005.7.15 " motor stator ", this stator will be arranged to helicitic texture for the inner peripheral surface of the through hole that dispels the heat, enlarge the area of dissipation in through hole, also reduced the refrigerant mobile speed of section within it, improved the radiating efficiency of motor, reached raising electric efficiency purpose, but still there are the problems referred to above in this motor stator, and in production process, scrappage is too high, is unfavorable for large-scale production.
The utility model content
For the present situation of above-mentioned prior art, technical problem to be solved in the utility model is to provide a kind of chamfering stator that can reduce scrappage.
The utility model solves the problems of the technologies described above the technical scheme that adopts: a kind of stator, comprise iron core, and described iron core comprises a plurality of independently iron core piecemeals, and described iron core piecemeal keeps together by insulating case, and this insulating case outside is provided with casing.
Further, described insulating case bottom is provided with chamfering, and this chamfering is 45 degree.
Compared with prior art, the utility model has the advantage of: the utility model is by in the insulating case bottom, chamfering being set, and after chamfering was set, stator can enter in casing very wellly, and scrappage can drop to 0.2%, has greatly improved success rate; The utility model is simple in structure, and security performance is high, is fit to large-scale promotion.
Description of drawings
Fig. 1 is the utility model structural representation;
On figure, numeral is as follows: 1-iron core piecemeal, 2-insulating case, 3-chamfering, 4-casing.
Embodiment
Below in conjunction with accompanying drawing, embodiment, the utility model is described in further detail.
Embodiment
As shown in Figure 1, a kind of stator, comprise iron core, and iron core comprises a plurality of independently iron core piecemeals 1, and iron core piecemeal 1 keeps together by insulating case 2, and these insulating case 2 outsides are provided with casing 4, and described insulating case 2 bottoms are provided with chamfering 3, and this chamfering is 45 degree.
Because insulating case 2 bottoms are provided with chamfering 3, just can be very well stator is put into casing 4, can not cause the damage of stator and casing, greatly improved qualification rate.
It should be noted that finally: above embodiment only, in order to the technical solution of the utility model to be described, is not intended to limit; Although with reference to previous embodiment, the utility model is had been described in detail, it will be understood by those of skill in the art that it still can modify to the technical scheme that aforementioned each embodiment puts down in writing, perhaps part technical characterictic is wherein replaced on an equal basis; And these modifications or replacement do not make the essence of appropriate technical solution break away from spirit and the scope of each embodiment technical scheme of the utility model.
Claims (2)
