To achieve these goals, the utility model is designed a kind of dc brushless motor stator structure, comprise coil, stator ring gear and stator yoke ring, described stator yoke ring set is connected on the stator ring gear, described stator yoke ring is combined into the yoke stack of laminations by some yoke sheets, also is provided with in the both sides of yoke stack of laminations and yoke sheet yoke reinforced sheet of the same size; Described stator ring gear is combined into the gear piece group by some gear pieces, described fluted disc is provided with the tooth of protrusion, be provided with and fluted disc fluted disc reinforced sheet of the same size in the both sides of gear piece group, the inboard of fluted disc is provided with several notches, and coil is installed on the tooth of gear piece group.
Be provided with the notch collets between two teeth of described gear piece group.
The inwall of described gear piece group is provided with several notches.
The both sides of described tooth are respectively arranged with the weld seam groove.
Described yoke reinforced sheet and fluted disc reinforced sheet are made by non-magnetic stainless steel.
This practical full mold dc brushless motor stator structure has following beneficial effect: (1) has solved high copper factor or be difficult to the difficult problem of the motor stator making of embedding coiling on interior circle, and can make motor performance unaffected.(2) can improve copper factor, promptly in same groove, can embed more copper cash, further improve the power machine of motor, improve the product level, remove the low production cost.(3) owing to realized the rule of cylindrical mode, help machine around implementation, also can independently make form-wound coil and assemble with iron core, this all will provide necessary precondition for realizing that motor stator is produced from action.

Embodiment
For the ease of those skilled in the art's understanding, structural principle of the present utility model is described in further detail below in conjunction with specific embodiment and accompanying drawing:
As Fig. 3, Fig. 4, Fig. 5, Fig. 6, Fig. 7, Fig. 8, Fig. 9, shown in Figure 10, design a kind of dc brushless motor stator structure, it comprises coil 3, stator ring gear 2 and stator yoke ring 1, described stator yoke ring 1 is socketed on the stator ring gear 2, described stator yoke ring 1 is combined into yoke stack of laminations 100 by some yoke sheets 11, also is provided with in the both sides of yoke stack of laminations 100 and yoke sheet 11 yoke reinforced sheets 12 of the same size; Described stator ring gear 2 is combined into gear piece group 200 by some fluted discs 21, described fluted disc 21 is provided with the tooth 23 of protrusion, be provided with and fluted disc 21 fluted disc reinforced sheets 24 of the same size in the both sides of gear piece group 200, the inboard of fluted disc 21 is provided with several notches 22, and coil 3 is installed on the tooth 23 of gear piece group 200.Be provided with notch collets 29 between two teeth of described gear piece group 200, notch collets 29 can be strengthened the notch location.The inwall of described gear piece group 200 is provided with several notches 22.The both sides of described tooth 23 are respectively arranged with weld seam groove 25.
The utility model dc brushless motor stator structure and traditional product are measure-alike in profile, but appearance is more attractive in appearance.The punching that traditional product stator ring gear uses is a complete slice, and being yoke portion with punching, the utility model type stator ring gear becomes yoke sheet and gear piece with teeth groove part separating making, omit notch simultaneously, make all teeth groove be connected to become the outside complete gear piece of opening, wherein yoke sheet internal diameter cooperates making with the gear piece external diameter by no gap, and available stamping-out processing is once gone out.The same with the method for making yoke sheet and gear piece, use not magnetic stainless steel making yoke reinforced sheet and tooth reinforced sheet, the shape of yoke reinforced sheet and yoke sheet are identical, and thickness is selected as required; The tooth body of tooth reinforced sheet and the shape and the gear piece of cylindrical are identical, and interior round size is also identical with gear piece, but interior circle and bottom land shape need design separately.Select for use purpose that magnetic stainless steel not makes yoke reinforced sheet and tooth reinforced sheet again in his intensity height, reinforcement effect is good, simultaneously, though the tooth reinforced sheet not otch do not have the shielding action of electromagnetic induction yet, can not influence motor properties.
As shown in Figure 5, when becoming yoke unshakable in one's determination, two ends increase the yoke reinforced sheet with yoke sheet system, and shape is identical with the yoke sheet, in the cylindrical position while welding they is welded into one.
As shown in Figure 7, when gear piece is made into fluted disc unshakable in one's determination, two ends increase the tooth reinforced sheet, the notch of tooth reinforced sheet on the groove position finally seals, but in order conveniently to leave the groove on the gear piece from now on, will precast a fluting undercut in this position, both are welded as a whole them in tooth both sides position while welding superimposed back.
As shown in Figure 9, fluted disc tooth body unshakable in one's determination is insulated, put notch insulation, make it behind otch, can play circumferential positioning action simultaneously, wind the line on one's body or embed prefabricated coil, finish the position of whole coils and work in tooth toward the fluted disc bottom land.
As shown in Figure 9, coil 3 is after in place finishing on the fluted disc unshakable in one's determination, with yoke heating collar unshakable in one's determination on the core tooth cylindrical, make yoke, increment in the face of neat, it is solid that seam points welds, and carries out follow-up works such as the yoke face insulation of coil and circumferential stretching then, handles in soak baking as integral body, in work, cut out on the circle at last this with regard to and the coil-induced notch that has, finish the making of new construction brushless DC motor stator.
Yoke reinforced sheet 12 described in the utility model and fluted disc reinforced sheet 24 are made by non-magnetic stainless steel.
