The disadvantages of this production method are: the part e of the PIN a inserted into the lower winding sleeve is required to be deep enough, which usually needs to be larger than 3mm, so as to ensure that the holding force of the PIN a meets the requirement and the PIN a cannot incline or fall off. However, on the ultra-thin fan, the e position on the lower winding sleeve is usually smaller than 3mm, so that the holding force of the PIN needle a is too small, even the PIN needle a falls off, and normal production cannot be realized.

The height of the E1 part is not affected by space and can be larger than 3mm because of the middle of the silicon steel sheet slot of the stator, thus solving the defect of the former stator winding mode. The drawbacks of this structure are: when the diameter of the fan is also very small, the stator silicon steel sheet groove space occupied by the part E1 is relatively large, as shown in fig. 3, the needle of the winding machine cannot extend to the bottom of the stator silicon steel sheet groove, so that the space in which the stator silicon steel sheet can be wound is greatly reduced, the coil F1 has a very small volume, the efficiency of the motor is reduced, and the performance is greatly reduced.
