Abstract: In an electrical generator, a connector for connecting stator coil sections and the method of making that connection, each coil section ending in a header cap of a predetermined geometry, and the connector being provided with openings of complementary geometry and spaced and aligned so as to receive the header caps. A recording tool is used for recording the spacing and alignment of a pair of header caps to be connected, the recorder being used in conjunction with a drill rig for drilling the openings in accordance with the recorded spacing and alignment information. The solid connector bar is placed over the header caps which are received within the drilled openings, and the bar is clamped onto the header caps with nuts.

Abstract: A spring support system for supporting a stator core (2) in a frame of an electrical machine, the core (2) having a longitudinal axis and an outer periphery provided with a plurality of circumferentially spaced, axially extending dovetail grooves (6), and the frame including a plurality of circular flanges (32) which surround the core (2) when the core (2) is installed in the frame, the system including:a plurality of key bars (8) each having a portion formed to mate with a respective dovetail groove (6) and each seated in a respective groove (6) of the core (2);a plurality of spring bars (34) each extending parallel to a respective key bar (8) and each secured to the flanges (32);a plurality of key blocks (20) for securing the key bars (8) to the spring bars (34); andfastening elements (26,40) mechanically fastening each key block (20) to a respective key bar (8) and to a respective spring bar (34) at a location between two axially adjacent flanges (32).
