摘要：
A stator coil production method using a plurality of shaping press pairs. A stator coil is made up of in-slot portions to be disposed in slots of a stator core and coil-end portions each of which extends every adjacent two of the in-slot portions. Each of the shaping press pairs has a die and a punch disposed on both sides of a conductor wire travel path. The method includes a first step of moving the die and the punch close to each other to shape a portion of a conductor wire into one of the coil-end portions, and a second 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 perpendicular to the conductor wire to shape a portion of the conductor wire into one of the in-slot portion.
