る。 Manufacturing of armatures for flat motors is generally done in the first stage.
As shown in the figure, the terminal wire of the single coil C and each segment of the commutator are electrically connected using a copper pipe A and a commutator B formed from a commutator piece machined from a copper bar material. After shaping the required number of single coils into a predetermined shape, the single coils and commutator are integrally fixed to each other by molding into insulating resin.
Furthermore, by cutting the outer diameter of the commutator and removing burrs and cutting powder between the commutator pieces, the outer periphery of the commutator is finished with high precision to complete the armature. In this case, since a pre-prepared commutator is used, it is necessary to integrally fix the commutator with the commutator during coil forming.Generally, the commutator body boss protrudes from the commutator, and the outer periphery of the body boss is knurled. is applied to form a bond with the mold resin. However, the adhesion between the commutator and the coil mold is achieved only by coating the knurled body boss with mold resin, so there is a limit to the adhesion strength, and expensive mold resin with excellent mechanical and adhesive properties is required. It is necessary to use it.

となつている。 In addition, the slits of the commutator have air-insulated intervals to improve heat dissipation, and when molding the coil, the slits must be sealed to prevent mold resin from entering the slits.Furthermore, after molding, When cutting the outer circumferential surface of the commutator to accurately finish it, this causes extra steps such as burrs on the commutator pieces and removal of cutting dust.

The feature is that the molded commutator can be completed at the same time as the coil molding.

First, as shown in Fig. 3, the same number of narrow grooves 1 as the commutator pieces are formed on the inner periphery of the copper pipe, grooves 3 forming commutator locking parts 2, and grooves 4 for connecting coil terminal wires are formed on one end of the copper pipe. The provided commutator piece material 5 is processed to form a protrusion in the narrow groove 1 of the commutator piece material 5 for sealing the groove 3 of the locking part and a part of the narrow groove 1, as shown in FIG. A mold 6 provided with molds 61 and 62 is used to fill a soluble resin 7, such as polyphenylene oxide resin. Next, as shown in FIG. 5, a predetermined number of terminal wires 81 of the fusible single coil 8 which have been wound and shaped in advance are inserted into the coil terminal connection grooves 4 of the commutator piece material 5 and connected. Furthermore, the single coils 8 connected to the commutator piece material 5 are each fixed at a predetermined position, and each single coil is fused and shaped to be integrated. Thereafter, as shown in FIG. 6, the single coil 8 and the commutator piece material 5, which are integrated with an insulating resin 9, are integrally molded.

ことができる。 Furthermore, in the final process of armature manufacturing, the commutator pieces are separated and independent for the first time by cutting the outer diameter of the commutator to complete the commutator, so it is possible to completely prevent damage to the commutator pieces and foreign matter from entering the slits. can. In addition, when cutting the outer diameter of the commutator, the slits are filled with soluble resin, so cutting is continuous and the outer circumferential surface of the commutator can be finished with high precision in one cutting, which prevents burrs from forming on one end of the commutator and prevents slits from forming. It is possible to completely suppress the intrusion of cutting dust and prevent short circuits between commutator pieces, making it possible to obtain a stable and high-quality commutator.
