Apparatus and methods for winding dynamo-electric machine stators with parallel wires

A plurality of wiring nozzles for use with apparatus that forms multiple wire stator coils, said wiring nozzles dispensing respective wires substantially simultaneously and movable around a wiring template;

• wherein:
• said wiring nozzles are aligned in a single plane;
• each said wiring nozzle is in a fixed position relative to other said wiring nozzles;
• and
• while moving around said wiring template, said wiring nozzles are in alignment with planes substantially parallel to said single plane.

A plurality of wiring nozzles for use with apparatus that forms multiple wire stator coils by winding multiple wires substantially simultaneously, said wiring nozzles dispensing respective wires substantially simultaneously and movable around a wiring template as follows:

• in a first direction around a side of said wiring template;
• in a second direction around a second side of said wiring template, said second direction substantially perpendicular to said first direction;
• in a third direction around a third side of said wiring template, said third direction substantially perpendicular to said second direction and substantially opposite and substantially parallel to said first direction;
• and
• in a fourth direction around a fourth side of said wiring template, said fourth direction substantially perpendicular to said third direction and substantially opposite and substantially parallel to said second direction;
• wherein:
• said wiring nozzles are aligned in a single plane;
• each said wiring nozzle is in a fixed position relative to other said wiring nozzles while moving in said first, second, third, and fourth directions;
• and
• while moving in said first, second, third, and fourth directions, said wiring nozzles are in alignment with planes substantially parallel to said single plane.
