Abstract: An apparatus (structure) is provided to support a superconductor winding (61) of an electromotive machine. An elongated loop (74) provides radial support to the winding. A base assembly (84) may include a base module (89) arranged to anchor the loop at a proximate end (76) of the elongated loop by way of a tubular coupling (86). The tubular coupling may further provide a mechanical connection relative to an axially-adjacent base module. A bracket assembly (100) may define an interior recess to receive a portion of the winding and to support the elongated loop at a distal end (78) of the elongated loop, such as by way of a support (80). A lateral-extending loop (106) may have a first end connected to the bracket assembly (100) and a second end connected to the base module (89) to transfer to the rotor core lateral loads, which may be experienced by the winding.

Abstract: The present invention increases the life of a pole crossover while minimizing the need for timely inspections and costly replacements. The present invention splits the pole crossover band 4 at one or more locations along its circumference and then joins the multiple arcs with a flexible member 10, such as an omega shaped bow. As deflection related stresses 8 increase, the circumference of the pole crossover band, the flexible member 10 allows for a natural expansion point in the otherwise rigid material. This relieves stresses that would otherwise be transferred to the connection point 6 between the pole crossover and the generator windings that can cause cracking and eventually generator failure.

Abstract: A method and associated apparatus (10) are provided for tightening slot wedges (32, 36) of a generator rotor. The method preferably includes the steps of positioning an electrically-conductive slot tightening member (25) within a recess (20) formed in at least one slot filler member (12, 16) positioned within a rotor slot (18) and positioning at least two end portions of electrically-conductive slot wedges (32, 36) to overlie the recess (20) and abuttingly contact at least portions of the slot tightening member (25) so that an electrically-conductive path is provided from one of the at least two end portions of the slot wedges (32, 36), through the slot tightening member (25), and to another one of the at least two end portions of the slot wedges (32, 36). The apparatus (10) preferably includes at least one slot filler member (12) for positioning within a rotor slot (18). The at least one slot filler member (12) has a recess (20) formed therein.
