ABSTRACT:
In accordance with the present invention there is provided improved winding retention means for the field coils in the stator of a rotary electric machine, particularly for coils which are wound in place on the field core by an automatic winding machine. As is well known, winding guides are temporarily secured at each axial end of the stator poles. The shuttles of the winding machine wind successive turns of wire around the poles and in the space between the latter and the winding guides. The retention means includes insulated flat steel wire or strips which [are secured to the core as by extending] extend through passages or slots formed in the core laminations. These strips extend out from [opposite ends of] the core [and] in both directions and are bent to form off-sets which bear against opposite ends of the core to prevent longitudinal displacement of the strips in the apertures. The end portions of the strips beyond the off-sets extend underneath the winding guides during the winding operation so as to support the coils after the winding guides have been removed and thereafter are bent around the coils so as to securely anchor the latter to the core and retain them in place.
