Abstract: A generator stator core has a plurality of axially extending radial slots arranged about the periphery thereof with windings in each of the radial slots. At least one adjustable wedge and slide assembly is located in each of the slots, arranged to restrain the windings, the assembly including a wedge component and a slide component which interface along respective sloped surfaces formed on respective sides of each of the wedge component and the slide component. The slide component is formed with a zone of laterally extending, discrete fingers on each side thereof that are angled relative to a longitudinal axis of the slide. The wedge component is slidably received in a pair of dovetail grooves in the radial slot with the slide component located between the wedge component and the windings such that the discrete fingers engage side walls of the radial slot.

Abstract: A multi-plane adjustable connector facilitates electromechanical connection between armature bar ends in a generator. The connector includes opposing end sections positionable in multiple orientations, and a plurality of interim sections coupled between the opposing end sections. The opposing end sections and interim sections are connected in a series via a plurality of hinges, respectively, where at least one of the plurality of hinges is angled relative to the others.

Abstract: A new and improved header design for a fluid tight, current carrying header that reduces direct contact between the liquid coolant and brazed joints. More specifically, the present invention provides for a header with hollow strands for carrying a coolant, and solid strands, the hollow strands being longer than the solid strands, the hollow strands grouped together at a first end of the header to form a hollow strand package, and the hollow strands and the solid strands grouped together at a second end of the header to form a mixed strand package. The hollow strand package may be fused to a liner of the header. This construction reduces water contact with the current carrying braze and groups the fluid carrying hollow strands in a separate hollow strand package where a reliable, corrosion-resistant metal fusing process can be applied to provide a reliable leak proof seal.

Abstract: A method of inserting a terminal stud adapter section of a terminal stud into the radial bore of a rotor, involving a tool, which includes an elongated tool body having a head at one end from which a pair of pins project. The head is preferably plated with copper. The head is received in the recess of a stud adapter section with the pins engaging in apertures in the adapter section. By inserting the adapter section in the radial bore of a rotor, the adapter section can be threaded to the bore copper. Upon removal of the tool from the recess of the adapter section, an outer section of the terminal stud is received within the radial bore and an inner end thereof makes electrical connection with the adapter section.

Abstract: A generator has a bore connector having a threaded radial opening for receiving a sectional terminal stud. The terminal stud includes an adapter section having threads on a radial inner end thereof for threaded engagement with the bore copper and a recess at its opposite end. An outer section of the terminal stud is received in the recess, making electrical connection therewith through an electrical connector. The outer section is maintained in the radial bore of the rotor by a threaded nut. The rotational orientation of the adapter section is fixed by its threaded engagement with the bore copper, while the outer section can be inserted without regard to rotational orientation, thereby facilitating refurbishment of the generator without remachining the bore copper.

Abstract: A generator stator includes a magnetic core having a plurality of axially extending radial slots arranged about the periphery thereof with stator windings in each radial slot. At least one adjustable assembly is located in an axially outermost end of each radial slot, arranged to apply radial force to the windings in the radial slot, the adjustable assembly including mating wedge and slide components which interface along stepped matching surfaces which lie at an acute angle to a center axis of the magnetic core. The assembly is adjustable in situ to compensate for decreases in radial pressure with time while stepped contacting surfaces of the wedge and slide prevent axial regression of the slide.
