Further, the upper and lower end face of described stator is provided with retainer ring near the position of inner ring, and the retainer ring is upper
Location arrangements between horizontally adjacent stator splicing group have through hole, through the pin of the projection of arc two ends both pass through it is right
The through hole in retainer ring answered.
Further, 1 self-clinching point is arranged with the arc basic courses department of described silicon steel sheet and outer toothed portion.
Beneficial effect：This utility model is related to a kind of default minor structure of external tooth of motor, by the way of splicing carries out group
Dress up stator, the utilization rate of sheet material can be greatly improved, moreover it is possible to be processed using the stamping machine of low tonnage, reduce equipment into
This, moreover it is possible to coiling is carried out to each branch first, then is assembled, do not limited by width of rebate, can be entered using coil winding machine
Row coiling, is suitable for the stator of various requirement, and adjacent splicing group connects by the way of breach and projection are mutually inserted, and protects
The compactness of splicing group connection is demonstrate,proved, has prevented magnetic field from leakage occur.
