ABSTRACT OF THE DISCLOSURE Method and apparatus for forming a stator for a dynamoelectric machine by inserting prewound coils into a slotted stator core in- cludes enlarging the slot openings or gap between certain adjacent pairs of stator, teeth, placing the prewound stator windings in se- lected stator core slots and thereafter reducing the slot opening or gap between those certain adjacent pairs of teeth. The disclo- sure apparatus includes a stator bore support and a series of punches to be placed in stator slots and collapsed radially in- wardly to bend the stator teeth tips to conform to the bore sup- port. An otherwise conventional coil inserting or injecting machine has unique accepting the respective formed stator teeth tips, and a pair of ribs outside the depression for spanning the corresponding tooth. Reforming of the stator teeth so as to provide a cylindri- cal bore stator may be accomplished by a plurality of cylindrical rollers which simultaneously engage the stator bore and traverse that bore interior surface to displace the stator teeth tips ra- dially outwardly, thereby providing a wound stator for further processing having a substantially reduced iron gap or for a given iron gap containing windings of a larger wire size than normally insertable in a stator having that iron gap. The slot openings may be enlarged either by mechanical forming of the stator tooth tips or the stator laminations may be initially stamped with this deformation so that the stator core or stack of such laminations need not be mechanically formed to increase the iron gap available for the wire insertion process.
