≤100mm。
It is understood that the sideline of the remote rotor hole 10 of each line embedding groove 20 is the circular arc concentric with rotor hole 10
Shape, and the Ratio control of 10 diameter of radius of circle and rotor hole is between 0.74-0.83, this ensure that coiling tooth 30 have it is enough
Winding space so that in the timing of size one of stator punching 100, can on coiling tooth 30 coiling it is more lower-cost
Aluminum steel, it is possible thereby to ensure in the case where motor highly has reached the limit, the incrementss of the loss of the stator winding of motor
Less than the incrementss of iron loss, due to the loss of stator winding be motor loss in proportion it is highest, hence in so that stator winding
Waste incrementss it is smaller, the loss of motor can be reduced to a certain extent, lift the performance of motor.Additionally due to around
The aluminum steel of coiling on line tooth 30, therefore reduce the cost of motor.
Stator punching 100 according to an embodiment of the invention, by reasonably design stator punching 100 overall dimensions and
The size of line embedding groove 20, the iron loss of motor and the loss ratio of stator winding are rationalized so that use the feelings of aluminum steel in stator winding
Under condition, still with preferable motor performance.

Gear line portion 320 can play the role of preventing winding from deviating from, and the angle in winding section 310 and gear line portion 320 is too small to reduce coiling
Space, winding section 310 is excessive with the angle for keeping off line portion 320 and can reduce the barrier effect in gear line portion 320.By winding section 310 with
The angle α for keeping off line portion 320 is controlled between 119 ° -121 °, not only can guarantee that the barrier effect in gear line portion 320, but can ensure around
The area of space of lines.Certainly, the corner dimension that user can adjust winding section 310 and keep off line portion 320 according to being actually needed.
In certain embodiments, as shown in Figure 1, each sideline of the line embedding groove 20 away from rotor hole 10 and stator punching 100
The minimum spacing at edge be W4, W4 meets relational expression：W4≥0.6*W3.It is possible thereby to ensure line embedding groove 20 and rotor hole 10
Sideline has enough distances, so as to ensure that the distance of coiling tooth 30 and 100 edge of stator punching, improves coiling tooth 30
Intensity.
