Ratio between the length L1 at edge is 2-2.2.The dimension scale more adduction between lug 200 and body 100 can so be made
Reason, makes the stress of stator punching 1 more reasonable.
Further, as shown in Fig. 2 the maximum length L in the horizontal of stator punching 1 and stator punching 1 in the vertical
The ratio of maximum length W is 1-1.2.Can so make the size of the entirety of stator punching 1 more uniform reasonable, so that further just
In the mechanical strength for ensureing stator punching 1.
Advantageously, as depicted in figs. 1 and 2, rivet point groove 210 is that length-width ratio is the rectangular channel of 2-4.So not only can be so as to
In the rivet locating effect for ensureing rivet point groove 210, and can be in order to reduce rivet point groove 210 in stator punching 1 radially
Size, in order to reduce the distance between rivet point groove 210 and slot for winding 112, so as to further reduce the obstruction to magnetic circuit.
More advantageously, as depicted in figs. 1 and 2, the bottom surface of the side long of rivet point groove 210 and neighbouring slot for winding 112 is most
Tangent line nearby is parallel.So not only can be in order to the setting of rivet point groove 210, and can be in order to ensure at lug 200
Structural strength, is easy to reduce the distance between rivet point groove 210 and slot for winding 112, so as to further reduce the obstruction to magnetic circuit.
Wherein, as shown in Fig. 2 the minimum widith of stator tooth 111 is L3, edge and the slot for winding 112 of rivet point groove 210
Half of the minimum range d more than L3 between perisporium.Can so make between rivet point groove 210 and stator winding with enough
Distance, so as to further reduce obstruction of the rivet point groove 210 to magnetic circuit.
Figures 1 and 2 show that according to one stator punching of specific example 1 of the utility model.As shown in figure 1, rivet point
There is spring to avoid interval 230 between groove 210 and mounting hole 220.Specifically, installation axle is combined with mounting hole 220, it is described
Spring is arranged with installation axle.Rivet point groove 210 can be so set to avoid spring, it is to avoid spring influence rivet point groove 210
Positioning.
