ABSTRACT:
A polyphase stator winding of a dynamoelectric machine including a plurality of multi-loop coils which are circumscribed about one another. Each coil has at least one loop that constitutes two coil sides (a top or radially inner conductor and a bottom or radially outer conductor) and two involuted connector rings segments.
The coil sides are embedded within slots formed in a tubular stator core and the connector rings are situated on both axial ends of the stator. The slots extend radially outward from the stator core's inner periphery. The top coil sides have varying lengths, extend beyond the end of the stator core, and are positioned around the stator's inner periphery such that no top coil side has a circumferentially adjacent coil side with an identical of axial overhang. Connections between top and bottom coil sides separated by a coil pitch is provided by two connected involuted connector ring segments.
