Align and set it on a round bar-shaped jig that matches the virtual circle formed by the arc-shaped tip of a , drive the cylindrical cutter from above and below so that the cutting length is the above dimension L, and cut the stator. The starting and ending ends of the coil 16 are held and cut. By cutting in this manner, it is possible to make the cutting length uniform and cut the stator coils 16 at once without cutting the starting and ending ends of a large number of stator coils 16 one by one, and automation becomes possible. After this cutting, the leading and trailing ends of the stator coil 16 are soldered. For this soldering process,
For example, a large number of stators 12, in which the starting and ending ends of the stator coils 16 are cut radially outward to a predetermined length and drawn out, are mounted on round rod-shaped shafts arranged in parallel on a solder bath (not shown). By fitting the stator 1 into the shaft and rotating the shaft, the stator 1
The starting and ending end portions of the stator coil led out radially outward from 2 are successively immersed in a solder bath to strip off the insulation coating and solder-fry them. That is, if the distance between the liquid level of the solder tank and the shaft is selected in advance from the dimensions of the soldering portion, it is possible to automatically perform the soldering process for a large number of stators with one revolution of the shaft.

According to the present invention, the starting and ending ends of the stator coil wound around each magnetic pole of the stator core are inserted into slit-shaped insertion grooves provided in the protective wall, pulled out radially outward, and cut into a predetermined length. Therefore, it is possible to automatically cut a large number of coils at the same time and easily to make the cutting length uniform, without having to cut the starting and ending ends of a large number of coils one by one by the operator. Furthermore, soldering of the leading and trailing ends of the stator coils after cutting can be carried out simultaneously without requiring much effort. Furthermore, the soldering connection to the connection terminals of the printed wiring board can be made by sequentially removing the starting and ending ends of the locked stator coil that is inserted into the insertion groove of the protective wall, so that the starting and ending ends of the coil can be easily connected. Even if there are a large number of wires, there will be no erroneous connection, and since the cutting lengths are uniform, the connection work can be performed accurately without causing disconnection due to strong tension. Furthermore, after connecting the coil to the printed wiring board, the starting and ending ends of the coil are isolated and insulated from the inner circumferential wall of the bracket by a protective wall, which prevents insulation defects and facilitates automation of coil terminal processing. This makes it possible to make it suitable for mass production, further improving work efficiency and quality, and making it possible to manufacture it at a low cost.
