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, with each coil portion extending around a different one of the plurality of teeth. The stator assembly further includes a plurality of connection portions each extending between two adjacent ones of the plurality of coil portions. A first set of consecutive ones of the plurality of coil portions is defined by a first continuous length of winding wire having two wire ends. Second and third sets of consecutive ones of the plurality of coil portions are each defined by respective continuous lengths of winding wire each having two ends.
