Wherein, the fixed form of described stator yoke and stator tooth comprises: welding, plastic packaging are fixed, Insulating frame is fixed or buckle connects.
Wherein, described first stator tooth is the first stamping.
Wherein, described second teeth are the second stamping, are fixed on described first stator tooth.
The beneficial effects of the utility model are:
Stator core is divided into the split of the laminated body of multiple stator yoke and the laminated body of multiple stator tooth, can be favourable carry out monodentate coiling, in concrete production process, can respectively by after independent for each split coiling, again each split complete for coiling is combined to form one-piece stator iron core vertically, because the laminated body of each stator tooth is independently arranged, when assembling, there is larger activity space on the laminated body both sides of each stator tooth, thus make separately when the laminated body coiling of each stator tooth the free activity space of bobbin winding head larger, be conducive to the winding efficiency improving stator core on the one hand, be conducive to the copper factor improving stator core on the other hand.Secondly, in the laminated body of stator tooth, one of them stator tooth adopts the first stator tooth, and remaining stator tooth adopts the second stator tooth, and the second stator tooth laminates on the first stator tooth, and convenient location, can reduce assembly error.Second stator tooth is separated into the second teeth, the second tooth root is separated the scheme arranged, and is separated into the simple monomer of less structure, makes to be not easy in parts production process damage, and enhances productivity.

Embodiment
By describing technology contents of the present utility model, structural feature in detail, realized object and effect, accompanying drawing is coordinated to be explained in detail below in conjunction with execution mode.
A kind of motor stator, comprise stator core and be set around the stator winding on described stator core, as shown in Figure 1, described stator core is the stack of laminations that the laminated body of at least one stator yoke 1 and the laminated body of at least one stator tooth 2 combine, stator yoke 1 quantity of each laminates of described stator core is identical with stator tooth 2 quantity, the two setting of mutually staggering in a circumferential direction; Stator core assembled after any two adjacent stator tooths 2 laminated body between enclose formation wire casing 5.A vertical view of stator core as shown in Figure 1, comprise stator yoke 1 laminated body and stator tooth 2 laminated body, the arc length of stator yoke 1 is identical with the arc length of stator tooth 2, can adopt identical module in the process of processing, and convenient processing, boosts productivity, and reduces production cost.
The laminated body both sides of each stator tooth 2 all have larger activity space before assembling, thus the activity space of the end of a thread is enough large when making coiling in independent each stator tooth 2 laminated body, improve winding efficiency and the tankful rate of stator core, be beneficial to and save material cost or can the material changing coiling according to demand be facilitated.The stator core that stator yoke 1 and stator tooth 2 are formed is that circumference is closed, and which ensure that the circularity precision of stator core, easy to connect between each parts, is beneficial to the production efficiency improving stator.
Concrete, described stator tooth 2 comprises the first stator tooth 6 and the second stator tooth, and the first stator tooth 6 comprises the first teeth and the first tooth root, and the first teeth and the first tooth root are wholely set, and the thickness of the first teeth is equal with the first thickness at root of tooth; Second stator tooth comprises the second teeth 3 and the second tooth root 4, second teeth 3 and the second tooth root 4 split and arranges, and the second teeth 3 laminate and are fastenedly connected in described first teeth;
The lamination body weight of each stator tooth described, one of them stator tooth is that the first teeth and the first tooth root are wholely set; Such employing first stator tooth 6 that facilitates gives the second stator tooth location, secondly all parts of the second stator tooth adopts finer structure, can improve the productivity ratio in parts generative process, improves the rate of finished products of product, reduce to produce error rate, thus can production cost be reduced.
