Cylindrical commutator and method of manufacturing the same

摘要

A cylindrical commutator is manufactured as follows. On the internal peripheral surface of a cylinder of base material having a plurality of hooks at one end, cuts are formed in a circumferential direction corresponding to the respective hooks, and projections are formed toward the inside by cutting. The base material is set to a molding die, and the prepared projections are embedded into the mold resin. Slits are processed at equal intervals in a circumferential direction on the external peripheral surface of the moldresin, and the hook and the prepared projection are divided for each segment. The segments are firmly integrated together with the mold resin. <IMAGE>
