A method of manufacturing an armature coil includes the steps of: stacking multiple armature coils to generate a stack of armature coils in a stacking direction as a first step; securing first and second ends of the stack of armature coils with a pair of clamping dies, respectively, as a second step after completing the first step; and sandwiching and depressing the stack of armature coils with pressing die in a given direction intersecting the stacking direction as a third step after completing the second step. The pressing die includes a pair of sandwiching dies to sandwich and depress the stack of armature coils in the given direction. The pair of sandwiching dies has a narrower interval at a position closer to a first end of the stack than that at another position closer to a second end thereof.

Method and system of manufacturing armature coil

A voltage control device for vehicle alternator has an IC chip as an electric component for controlling electric circuits, terminals connected electrically to the IC chip for controlling electric circuits, a resin case in which the terminals are formed by insert molding, and a terminal exposure portion of a hole shape, formed in a part of the resin case, corresponding to a positioning pin for positioning the terminals. A projection part as a positioning member of a wall shape is formed in the surroundings of the terminal exposure portion and on the surface of the resin case.
