Abstract: Apparatus for automatically inserting coils and wedges of proper dimensions into a stator core which may be any one of various lengths. The apparatus includes support structure which supports a stator core of a given length. The support structure also supports mechanism for insertion of prewound coils into the stator core. The support structure also supports a coil carrying tool which carries coils for insertion into the stator core. The support structure has relatively movable parts which move in proper relationship to each other and to the stator core for transferring prewound coils from the coil carrying tool to the slots of the stator core. The support structure also supports a wedge magazine which retains wedges of a proper length for the stator core of a given length. The support structure also supports a wedge guide unit and a wedge pusher unit which automatically operate to insert wedges of the proper length into the stator core.

Abstract: Apparatus for precision level winding of coils. The apparatus is particularly adapted for precision level winding of a continuous set of coils, in which each of the coils in the set may have a number of turns differently from each of the other coils in the set and may be of a length and pitch different from each of the other coils in the set.The apparatus includes means for automatically applying coils of wire to a coil holder member which has a plurality of aligned substantially coaxial levels.The apparatus includes control means by which each of the variables involved is readily adjustable.There is relative axial movement between a rotary wire-laying flyer and the coil holder member. The apparatus includes means for applying a desired number of turns of wire to each level in a manner such that the spacing between turns is substantially constant, and the number turns applied to each level adjusted readily and easily.
