Screw type stator piece, solves existing stator punching waste of material greatly, the problem of electromagnetic conversion rate is not high.
To achieve these goals, the technical scheme that the utility model is used for：
A kind of screw type stator piece, the stator piece of the spiral forming of vertical bar curling, the stator piece stress of the spiral forming
Laminating is laminated up and down, and the stator piece includes circular yoke portion, and the yoke portion extends provided with punching inwardly along annulus radial direction
Piece tooth, punching tooth is arranged along the axial uniform intervals of annulus, and punching groove, the periphery in the yoke portion are constituted between two neighboring punching tooth
It is interval with positioning scalloped recess；The circle diameter in the yoke portion is D, and the circle diameter of the locating slot is d, the positioning fan
The fan-shaped center of circle of connected in star to the outer peripheral beeline in yoke portion be X, wherein, X≤1/3*d, positioning scalloped recess sector circle
The heart encloses the diameter of a circle D1=D+2*1/3*d to be formed.
Wherein, the increment of the punching tooth is T-shaped.
Wherein, the stator piece is that vertical bar curling is integrally formed.
The beneficial effects of the utility model are：
Traditional stator punching is laminated into the stator of dimension using direct punch forming by laminating tool again,
Screw type stator piece of the present utility model is rushed using vertical bar, then by the semi-finished product that vertical bar is swept away be wound into the stator of dimension into
Product, with traditional punching process ration, waste material of the present utility model is greatly reduced, and can preferably utilize material, Gong Rengeng
Easily operation, saves the time, and cost of labor reduction, efficiency is improved.In addition, the diameter of the positioning scalloped recess is by science essence
It is close to calculate, greatly improve the conversion ratio of electromagnetism.

Embodiment
The utility model is described in detail below with reference to embodiment shown in the drawings.But these embodiment party
Formula is not intended to limit the utility model, structure that one of ordinary skill in the art is made according to these embodiments, method or
Conversion functionally is all contained in protection domain of the present utility model.
Refering to a kind of screw type stator piece shown in Fig. 1 to Fig. 5, the stator piece 1 of the spiral forming of vertical bar curling, the spiral shell
Fit and laminate above and below the stress of stator piece 1 for revolving shaping, the stator piece 1 includes the yoke portion 11 of annular shape, the yoke portion 11 is along circle
Ring radial direction extends provided with punching tooth 13 inwardly, and punching tooth 13 is arranged along the axial uniform intervals of annulus, two neighboring punching tooth
Punching groove 12 is constituted between 13, the periphery in the yoke portion 11 is interval with positioning scalloped recess 14；The circumference in the yoke portion 11 is straight
Footpath is D, and the circle diameter of the locating slot is d, and the fan-shaped center of circle of the positioning scalloped recess 14 is outer peripheral most to yoke portion 11
Short distance is X, wherein, X≤1/3*d, the fan-shaped center of circle of positioning scalloped recess 14 encloses the diameter of a circle D1=D+2*1/ to be formed
3*d。
Traditional stator punching is laminated into the stator of dimension using direct punch forming by laminating tool again,
Screw type stator piece 1 of the present utility model is rushed using vertical bar, then the semi-finished product that vertical bar is swept away are wound into the stator of dimension
Finished product, with traditional punching process ration, waste material of the present utility model is greatly reduced, and can preferably utilize material, workman
It is easier to operate to, saves the time, cost of labor reduction, efficiency is improved.
In addition, the diameter of the positioning scalloped recess 14 is calculated by science precision, the conversion ratio of electromagnetism is greatly improved.Such as
Shown in Fig. 4, the electromagnetic conversion rate produced by ratio different X/d, in X/d=1/3 position, electromagnetic conversion rate is occurred in that substantially
Change, obtain the electromagnetic conversion rate highest as X≤1/3*d by numerous experiments.Present embodiment X/d uses special setting
