Owing to there being the groove depth H of part winding slot to be less than the groove depth H of all the other winding slots in the winding slot in the stator punching of this programme, and the less winding slot of this part groove depth H is symmetrically distributed in the relative both sides of punching body; Can make like this width of punching body reduce, thereby the outline of punching body is designed to rectangle; Thereby when the moulding of stator punching stamping-out, can reduce greatly the generation of waste material, and improve steel disc utilance, reduce production costs.On the other hand, because the groove depth H of a part of winding slot in the stator punching of this programme is larger, it has increased the sectional area of winding slot; Thereby the winding in increase winding slot, improves motor working efficiency.
As preferably, punching body outline is rectangular, the winding slot that in described winding slot, groove depth H is less is distributed on the punching body inward flange corresponding with the long limit of punching body outline, and all the other winding slots are distributed on the punching body inward flange corresponding with punching body outline broadside.The winding slot that in this programme winding slot, groove depth H is less is distributed on the punching body inward flange corresponding with the long limit of punching body outline, and all the other winding slots are distributed on the punching body inward flange corresponding with punching body outline broadside; This rectangular configuration that takes full advantage of punching body designs winding slot, not only can guarantee the structural strength of stator punching, and makes the distribution of the magnetic line of force on stator punching more evenly reasonable, has improved the efficiency of motor.
As preferably, on the punching body inward flange corresponding with the long limit of punching body outline, the groove depth H of each winding slot is increased toward both sides gradually from the middle part on the long limit of punching body outline.In the winding of this programme structure in increasing winding slot, make the distribution of the magnetic line of force on stator punching more evenly rationally, improved the efficiency of motor.
As preferably, in the middle part of two long limits of punching body outline, be distributed with ，Qie Liang reinforcement part, outwardly reinforcement part and be symmetrical arranged.The setting of this programme reinforcement part has not only strengthened punching body intensity, and makes the distribution of the magnetic line of force on stator punching more evenly reasonable.
As preferably, edge, reinforcement part is provided with some depression breach.Depression breach be provided with the heat radiation that is beneficial to punching body.
As preferably, the both sides of wire winding pole end divide other to be provided with block, and two blocks are symmetrical arranged; In described each block end, by Yi Ce turning, punching body center, be fillet.Block the copper factor that can improve winding slot is set; And by Yi Ce turning, punching body center, be fillet in each block end, in the time of can avoiding winding the line, scratch the insulating barrier of winding.
As preferably, the turning by winding slot one side in each block end is wedge angle, and the angle of wedge angle is greater than 90 degree.
As preferably, winding slot takes the shape of the letter U, and is less than the groove width by the winding slot of winding slot bottom by the groove width of the winding slot of winding slot notch.
As preferably, the reinforcement wire casing of depression is established respectively in the bottom of each winding slot that in winding slot, groove depth H is less.Due to the setting of reinforcement wire casing, while laying winding in it, not only increase the winding in winding slot, and can further improve the distribution of the magnetic line of force on stator punching, improved the efficiency of motor.
The beneficial effects of the utility model are: not only can improve steel disc utilance, reduce production costs; And can improve motor working efficiency.
