ABSTRACT:
An interconnecting assembly (100) for a rotor assembly of a dynamoelectric machine is provided. The interconnecting assembly may be part of an electrically conductive path generally extending from a radially inward section of the rotor assembly to a top winding of a stacked winding (128) located at a radially outward section of the rotor assembly. The interconnecting assembly may include a first connecting member (106) connected to a radial lead (104) at the inward section of the rotor assembly. This first connecting member is made up of multiple conductive leaves and includes a flexible bend (108) positioned to provide a resilient-connection relative to at least a radial direction. The interconnecting assembly may further include a second connecting member (124) mechanically connected to the first connecting member by way of the resilient connection. This second connecting member is electrically connected to the first connecting member and to the top winding. The second connecting member may include a stiffener (138) for providing support relative to an outer portion of the bend to increase stiffness and prevent buckling of the bend due to a centrifugal force that develops during operation of the machine.
