摘要 |
A method of manufacturing an armature of an electric rotary machine comprising the step of: fixedly attaching an armature core to a shaft which is a constituent component of the armature; winding armature coils in slots formed in the outer circumference of the armature core, the lower and upper lead-out portions of the armature coils being axially extended to a commutator arrangement space where a commutator is to be arranged; welding the respective end portions of each pair of the upper and lower lead-out end portions so as to join the upper and lower lead-out end portions in each pair with each other under the condition that the upper and lower lead-out end portions in each pair are arranged vertically one on the other and parallelly to each other while securing concave portions at the welding-joined portions to thereby form each of commutator segment portions; arranging the commutator segment portions in alignment at predetermined intervals circumferentially around the shaft; and molding and fixedly attaching an annular resin-molding body which will be made to be a body of commutator at the commutator arrangement space around the shaft in a manner so that the commutator segment portions are fixedly embedded in the annular resin-molding body, that the outer peripheral portions of the commutator segment portions are exposed from the outer circumference of the annular resin-molding body to enable a commutator brush to slidably contact with the outer peripheral portions of the commutator segment portions, and that the concave portions provided at the welding-joined portions of the commutator segment portions are filled with the resin of the annular resin-molding body. |
