An interconnecting assembly for a rotor assembly of a dynamoelectric machine is provided. The interconnecting assembly may be part of a conductive path generally extending from a radially inward section of the rotor assembly to a winding located at a radially outward section of the rotor assembly. The interconnecting assembly may be made up of a flexible member () comprising a bend (). The interconnecting assembly may be further made up of a connector () connected to the flexible member to pass axial and radial forces that develop during operation of the machine. The positioning of the connector relative to the flexible member may be arranged so that an effect of an axial force on a radius of curvature of the bend and an effect of a radial force on that radius of curvature are opposed to one another. This leads to lower peaks of mechanical stress at the flexible member () (e.g., J-strap), which in turn leads to a relatively more durable and reliable conductive path for the rotor assembly of the dynamoelectric machine.

Generator rotor lead path for connecting to a field winding

An interconnecting assembly () 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 () located at a radially outward section of the rotor assembly. The interconnecting assembly may include a first connecting member () connected to a radial lead () at the inward section of the rotor assembly. This first connecting member is made up of multiple conductive leaves and includes a flexible bend () positioned to provide a resilient-connection relative to at least a radial direction. The interconnecting assembly may further include a second connecting member () 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 () 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.
