Title: Method and apparatus for placing wire coils with varied lengths on dynamo electric motor stators

Abstract: An apparatus for forming varied length wire coils for insertion stator core slots includes a template positioned that is configured to vary a length of consecutive wire turns while wire is received from a flyer winder. The wire turns may then be inserted into a pair of stator core slots depending upon their respective lengths. A method of using the apparatus to form a winding with varied length turns includes depositing wire turns on a template, varying a length of at least two consecutive wire turns as the wire is deposited on the template, removing the wire turns from the template, and inserting the removed wire turns into a stator core slot.
