ABSTRACT:
The invention relates to a device and a method for the insertion of pre-wound coils into the slots of a stator of a rotary electric machine. The device comprises a cylindrical finger holder having on its periphery an annular series of longitudinal grooves, housing a series of fingers which extend beyond one end of the finger holder to receive the pre-wound coils. At the other end of the cylindrical finger holder opposite that from which the fingers extend is an end portion which is insertable into a stator and is provided with reference means for determining the correct angular orientation of the finger holder and the fingers with respect to the stator slots when the said other end portion of the finger holder is inserted into the interior of a stator. The device further includes means for drawing the finger holder right through the stator, with the said other end portion as the leading end, after this latter has been introduced into the stator, so that the fingers carrying the pre-wound coils are drawn through the stator in the correct angular orientation to effect insertion of the pre-wound coils carried by the fingers into the stator slots.
