Abstract
The utility model relates to a motor, in particular to a direct current brushless motor stator used for the drive fans of the indoor machines and the outdoor machines of frequency conversion wall hanging type fission air conditioners. The direct current brushless motor stator is formed from the stamping of a plurality of layers of silicon steel sheets. A crooked hole and a dilatation joint are provided on the connecting position of two T shape iron sheets. The design can make the direct current brushless motor stator be completed by disposable stamping, the qualification rate of products is considerably enhanced, and the production efficiency of the products is enhanced.
Description
Technical field: the utility model relates to a kind of motor, particularly relates to a kind ofly to be used for that frequency conversion wall-hanging split-type air conditioner is indoor, the dc brushless motor stator of off-premises station drive fan.
Technical background: at present, it is indoor to be used for frequency conversion wall-hanging split-type air conditioner, the coiling of the dc brushless motor stator of outdoor drive fan is a great problem during motor is made always, because inwardly stretching out, the core magnetic pole of stator is the T font, generally all adopt 12 independent T font stator core magnetic poles, be welded into whole stator after coiling more one by one, its product percent of pass and production efficiency are all very low.The purpose of this utility model just provides a kind of brand-new design thinking, can improve the quality of product significantly, and production efficiency is significantly improved also.
Summary of the invention: the purpose of this utility model is achieved in that a kind of dc brushless motor stator is to have the several layers iron plate to be stamped to form.It is characterized in that: the central authorities at T sections sheet are provided with location hole, have bent hole and expansion joint in the junction of every T sections sheet and T sections sheet, and the expansion joint links to each other with bent hole, and the stator of being made up of the several layers iron plate is to be stamped to form by mould is disposable.It is simple and convenient that the utility model is made, and precision height, easy and safe to operate, productivity ratio are significantly improved.
Description of drawings: Fig. 1 is the structural representation of a kind of dc brushless motor stator described in the utility model
1, stator 2, location hole 3, bent hole 4, expansion joint
Embodiment: as can be seen from Figure 1, dc brushless motor stator 1 is to have the several layers silicon steel sheet to fold through the automatic riveting of high velocity ram machine punching press to form, difference according to motor necessary requirement performance, determine the thickness that the silicon steel sheet riveting is folded, it is characterized in that: being provided with location hole 2 in the central authorities of T sections sheet can fix 12 T sections cores, junction at every T sections sheet and T sections sheet has bent hole 3 and expansion joint 4, and expansion joint 4 links to each other with bent hole 3, the stator that the several layers iron plate is formed is after location hole 2 is fixed, at high velocity ram machine punching press once-forming, stator punching after the shaping puts corresponding insulating case again, adopt three-dimensional bull flying trident to wind the line simultaneously then, neat winding displacement lays out stator coil, can improve the qualification rate and the production efficiency of product significantly.
