Abstract:
1. A method of producing a stator coil of a stator for use in an electric rotating machine using a plurality of shaping press pairs, the stator coil being made up of in-slot portions which are to be disposed in slots of a stator core and coil-end portions which are to be disposed outside the slots and each of which extends between every adjacent two of the in-slot portions, each of the shaping press pairs having press members opposed to each other across a travel path along which an insulator-coated conductor wire is to travel, the method comprising: a moving step of moving all the shaping press pairs along the travel path; a coil-end portion shaping step of moving the press members of one of the shaping press pairs close to each other to shape a portion of the insulator-coated conductor wire into one of the coil-end portions; and an in-slot portion shaping step of bringing adjacent two of the shaping press pairs close to each other and simultaneously moving one of the adjacent two of the shaping press pairs in a direction substantially perpendicular to a length of the insulator-coated conductor wire to shape a portion of the insulator-coated conductor wire into one of the in-slot portion.
