Abstract
An apparatus for inserting coils and wedges into the stator core of an electric motor. The apparatus includes a plurality of elongated blades arranged in a circular array, a plurality of wedge guides arranged in a circular array, and a stripper. Additionally, a wedge guide support is provided which moves axially together with the blades and which supports the wedge guides when coils are inserted into a long stator core. The wedge guide support prevents deflection of the wedge guides radially inward by pressure of the coil end turns on the wedge guides when the blade pack is axially moved out of the wedge guides.
