Stator assemblies for three phase dynamoelectric machines and related winding methods

Abstract:

According to some aspects of the present disclosure, example stator assemblies for three phase dynamoelectric machines and related winding methods are disclosed. An example stator assembly generally includes a non-segmented stator core including a stator yoke and a plurality of teeth. The stator assembly also includes a plurality of coil portions electrically coupled in a delta winding pattern, and including a first coil portion extending around a first one of the plurality of teeth and a second coil portion extending around a second one of the plurality of teeth. The stator assembly further includes a plurality of connection portions including a first connection portion extending between the first coil portion and the second coil portion and electrically coupling the first coil portion and the second coil portion. The first coil portion, the second coil portion and the first connection portion are defined by a continuous length of winding wire.
