Claim:
A method of winding a dynamo-electric stator, the method comprising: providing a stator having a plurality of radially inwardly extending teeth; providing a plurality of wire turns around each of said teeth to form a wire winding on each of said teeth, said windings comprising first, second and third phase windings; each said winding comprising a primary lead defined by a free end of said wire forming said winding and a secondary lead defined by a free end of said wire forming said winding, said primary and secondary leads extending from opposite sides of a respective tooth on a termination side of said stator; each said phase comprising a plurality of said windings wherein each said phase comprises a winding having a primary lead defining a primary base lead, a winding having a secondary lead defining a secondary base lead, two or more windings having primary leads defining at least an initial primary wrap lead and a last primary wrap lead, and two or more windings having secondary leads defining at least an initial secondary wrap lead and a last secondary wrap lead; performing an end wrapping operation for each phase comprising: wrapping said initial primary wrap lead in a first circumferential direction around said termination side of said stator to a primary base lead of a respective phase; wrapping said last primary wrap lead in a second circumferential direction, opposite to said first direction, around said termination side of said stator to said primary base lead of a respective phase; wrapping said initial secondary wrap lead in said first circumferential direction around said termination side of said stator to a secondary base lead of a respective phase; wrapping said last secondary wrap lead in said second circumferential direction around said termination side of said stator to said secondary base lead of a respective phase; joining the wrap leads associated with each of said primary and secondary base leads to form a primary and secondary lead connection for each of said phases, said joining comprising connecting free ends of respective windings in engagement with each other for each of said primary and secondary lead connections; and wherein said initial wrap leads comprise first wrap leads and said last wrap leads comprise third wrap leads, and further comprising a second primary and secondary wrap lead for each phase, said end wrapping operation further comprising, for each phase: wrapping said second primary wrap lead in said first direction around said termination side of said stator to a primary base lead of a respective phase; and wrapping said second secondary wrap lead in said first direction around said termination side of said stator to a secondary base lead of a respective phase.
