The slots (8) are wound in a wound shape, and the winding end portion is twisted to another predetermined pin body (27) to form a main coil (32) in the lower part. Then, similarly, the slot (8) is arranged so that the coil (30) is located above the main coil (32).
The auxiliary coil (34) is formed by winding and winding the space in a well-wound shape. In this case, as shown in FIG. 4, the winding end portion (37) of the auxiliary coil (34) is overlapped and connected to the winding end portion (35) of the main coil (32), and the common portion (29). ) Is formed. The main coil 32 and the auxiliary coil (34) are formed by dipping and soldering the pin body (27) to which the winding start portion (34a) of the main coil (32) and the winding start portion (36) of the auxiliary coil (34) are connected. ) And a pin (28). In addition, since the common part is only entangled and not conducting, a predetermined voltage is applied between the pins (28) and the withstand voltage is checked, so that the main coil (32) and the auxiliary coil (34) are separated from each other. Interphase breakdown voltage inspection is performed. After that, the common part (29) is dip-soldered so that the winding end (35) of the main coil (32) and the winding end (37) of the auxiliary coil (34) are simultaneously conducted to the pin (28). The inner ring magnetic pole part (10) is press-fitted into the outer ring yoke (5) heated by a heating medium (not shown), and the yoke part (5) is cooled through the fitting recess (6a). Due to the contraction, the outer ring yoke portion (5) and the inner ring magnetic pole portion (10) are securely fitted to each other to form the stator core (6). Further, as shown in FIG. 3, a wedge (39) is attached to insulate the coil (30) from the yoke portion (5). Next, the coil (30) is heated to melt the fusion layer of the magnet wire of the self-adhesive material to fix the gaps between the coils (30), and the rotating shaft (17) has the bearing (40) and E.
After mounting the die retaining ring (40a), press the stator iron core (6) into the frame (42) and insert the protruding piece (47) of the bracket (46) into the caulking recess (45) of the frame (42). Then, the bracket (46) is put on the frame (42) from above, and the convex piece (47) is attached to the frame (4) as shown in FIG.
Bend the flange (43) of 2) so that it is held, and connect it. On the other hand, a capacitor (53), a thermal fuse (54) and the like are mounted on the terminal block (50) by molding the lead wire (55) into a predetermined shape. Then, the leg portion (51) is inserted by inserting it into the through hole (49) of the bracket (46). in this case,
The winding frame column (22) part of the inner ring magnetic pole part (10) is inserted into the leg part (51) of the terminal block (50), positioned and fixed, and the tip of the lead wire (55) is orthogonal to the pin body (27). Then, an electrode is applied to the portion to be superposed and spot welding is performed to join them. Next, a contact (not shown) for inspection is brought into contact with the pin body (27), and a voltage is applied to carry out a motor performance inspection of a predetermined item. Then, the power cord (56) is arranged on the terminal block (50), and the tip end thereof is temporarily fixed so as to be orthogonal to the pin body (27) and joined by spot welding. Furthermore, the putty (57) is filled on the terminal block (50) to insulate the charge exposed parts such as the lead wires (55), fix the electronic parts and the power cord (56), and mold them. Finally, the power cord (56) is pulled out from the protruding portion (62) and the cover (58) is fitted to the bracket (46).

As described above, according to the present invention, the outer ring yoke portion forming the outer ring portion, and the stator iron core formed by fitting the inner ring magnetic pole portion formed of a plurality of magnetic pole pieces having slots in the outer ring yoke portion, An insulating portion for covering the inner ring magnetic pole portion of the stator core and a winding frame column projecting with a pin on the magnetic pole piece are provided integrally with the insulating portion to insert the rotor into the inner ring magnetic pole portion, A stator formed by winding a coil wound around the pin between the slots, and a through hole of the winding frame column provided in an outer casing in which the stator is installed, and the through hole is provided so as to project from the through hole. A terminal block mounted on a reel and having an electronic component connected to the pin, and a cover for covering the terminal block are formed, and the cover is formed in a bottomed shape having an opening on one side, and the cover is opposed to the opening. Since the side wall that has a rounded protruding portion is integrally formed, The power cord connected to the stand is pulled out from the protruding part, and even if it contacts the protruding part, the power cord is not damaged.Therefore, the power cord is pulled out from the protruding part without using the cord bush. Since it is easy to pull out the power cord, it is not necessary to process the cord hole and the cost is low, and it can be mounted on the outer casing only by pushing from above, and the assembly can be automated.
