Abstract: Disclosed is a dynamoelectric machine stator winding having a plurality of coil sides of varying lengths disposed in a plurality of slots located around the inner periphery of a tubular stator core. Top and bottom coil sides (radially inner and outer positions) of unequal length are placed within the slots and interconnected such that top coil sides are joined to bottom coil sides disposed in other slots when the top coil sides, as dictated by winding topology (for phase interspersed connector ring segments), are longer than the commonly slotted bottom coil sides. When the bottom coil side in a subject slot is longer than the commonly slotted top coil side, the top and bottom coil sides are lengthened and shortened, respectively, and the top and bottom coil sides in the subject slot are respectively joined to top and bottom coil sides on both axial ends of the stator.

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.

Abstract: A dynamoelectric machine having two radial layers of connector ring segments arranged in the end regions of its stator. Each connector ring segment joins two coil sides embedded within circumferentially separated stator slots. Each double radial layer of connector ring segments is disposed at a discrete axial location with the connector ring segments being interspersed according to phase to minimize forces thereon.
