ABSTRACT:
The present invention generally relates to a coil insertion device for inserting a stator coil into a slot defined within a stator core of an electric rotary machine and to an improvement in a mechanism for inserting a stator coil into a slot. The coil insertion device includes a plurality of clamping guides moveable along the inner peripheries of the stator core and the base body and circumferentially arranged in a regularly spaced relationship, a plurality of coil clampers arranged radially inward and in opposition to the clamping guides for clamping a prewound stator coil in an aligned condition with the clamping guides and for shifting upward according to an upward movement of the clamping guide to draw the stator coil into the slots at a given angle of tilt, and a plurality of blades moveable along the inner periphery of the base body, the blades being formed in an essentially identical configuration and having essentially the same arrangement as the clamping guides 52, thereby permitting a stripper extending therethrough to push the stator coil into the slot by an upward movement after an insertion by the coil clampers.
