Stator assemblies for three phase dynamoelectric machines and related winding methods

A stator assembly for a three phase dynamoelectric machine, the assembly comprising:

• a non-segmented stator core including a stator yoke and a plurality of teeth extending from the stator yoke toward a central opening, the central opening extending from a first end of the stator core to a second end of the stator core opposite the first end, the plurality of teeth spaced apart from one another and defining a plurality of slots between the plurality of teeth for receiving windings of the stator assembly;
• a plurality of coil portions electrically coupled in a delta winding pattern, each coil portion extending around a different one of the plurality of teeth and through slots on each side of said different one of the plurality of teeth;
• and
• a plurality of connection portions, each connection portion extending between two adjacent ones of the plurality of coil portions and electrically coupling said two adjacent ones of the plurality of coil portions;
• wherein a first set of consecutive ones of the plurality of coil portions and the connection portions coupled therebetween are defined by a first continuous length of winding wire having two wire ends, wherein a second set of consecutive ones of the plurality of coil portions and the connection portions coupled therebetween are defined by a second continuous length of winding wire having two wire ends, and wherein a third set of consecutive ones of the plurality of coil portions and the connection portions coupled therebetween are defined by a third continuous length of winding wire having two wire ends.
