Abstract
A multiphase stator winding for a dynamoelectric machine constituting a plurality of coil loops each of which have a plurality of coil sides of varying lengths that are embedded in stator core slots. Each coil loop has two straight coil sides embedded within the stator slots and an annular connector ring segment which connects the two straight coil sides in an end region of the stator. The connector ring segments are interspersed in the axial direction so that connector ring segments of identical phase are separated by connector ring segments of other phases.
