Methods for setting insulators and pressing end turns

A method of setting at least one insulating wedge in a stator assembly by moving wedge setting means, including an elongate surface, radially relative to the stator assembly while the elongate surface is in engagement with the wedge, and thereby moving at least part of the wedge in a radial direction relative to an axially extending slot of a stator core;

• and substantially simultaneously therewith changing the shape of at least part of the end portions of a plurality of winding turns supported on the core by moving means for shaping end portions of winding turns while the means for shaping is in pressing engagement with such at least part of the end portions, the method comprising:
• positioning the stator assembly in predetermined relation to radially movable wedge setting means including the elongate surface at a first station;
• holding the stator assembly in fixed relation to the wedge setting means and, while so holding the stator assembly, generally concurrently setting the at least one wedge and shaping the at least a portion of the plurality of winding turns by moving the wedge setting means radially relative to the stator assembly while the wedge setting means is in camming and driving engagement with the means for shaping end portions and while the elongate surface is in engagement with the wedge, whereby radially moving the wedge setting means causes axial movement of the means for shaping end portions and associated shaping of winding turn end portions engaged thereby and also causes radial movement of the elongate surface and setting of a wedge engaged thereby;
• and thereafter moving the stator assembly away from the wedge setting means.
