摘要： A rotary transformer has a bus duct assembly that extends through the hollow shaft of a rotary transformer from collector or slip rings positioned above a drive motor for the rotary transformer to end windings of the rotor positioned most remote from the drive motor. By positioning the leads of the bus duct connection with the rotor end windings on the rotor end windings most remote form the drive motor, the shaft strength and integrity is not reduced due to the torque applied by the drive motor. Further, the shaft is formed from two coupled shaft sections and the bus duct assembly comprises two L shaped sections each positioned substantially within a corresponding shaft section. The bus duct sections are interconnected to complete the bus duct assembly making it simpler to remove the first or upper shaft section from the second or lower shaft section during field servicing. Further, the use of the two bus duct sections within the shaft coupled together simplifies assembly of each bus duct section within its corresponding shaft section.

摘要： An insulated core stud for use in the core structure of at least one of a stator and a rotor of a dynamoelectric machine is adapted to pass through holes contained in laminations of the core structure. The insulated core stud has a central portion and a first layer of heat shrinkable tubular insulation shrunk fit onto and covering at least the central portion of the core stud that passes through the laminations. One or more additional layers of heat shrinkable tubular insulation are shrunk fit onto at least a portion of the first layer of insulation that passes through the laminations. These second layers provide mechanically protection. to the underlying layers of insulation against breaks occurring in the electrical insulation when the laminations and core studs are assembled into the core structure.

摘要： A dual shaft and rotating machine coupling has a first rotatable shaft, a second rotatable shaft and a rotating machine rotor coupling. The first rotatable shaft has a first shaft connecting flange radially extending outwardly therefrom. The second rotatable shaft is axially aligned with the first rotatable shaft and has a second shaft connecting flange radially extending outwardly therefrom. The second shaft connecting flange is spaced from the first shaft connecting flange. The rotating machine rotor coupling has a rotor spider and a rotor connecting flange radially extending inwardly from the spider securely sandwiched between and in abutting relation with the first and second shaft connecting flanges.

摘要： An isolated phase bus duct joint assembly couples together first and second phase bus duct sections where each section has an interior bus conductor surrounded by an outer housing. The joint assembly couples end portions of the interior bus conductor and has first and second conductor coupling portions each extending from the end portion of one of the interior bus conductors. Each coupling portion has a reduced outside dimension relative to the interior bus conductors. The joint assembly has a plurality of movable electrical contact fingers mounted by spring loaded adjustment fasteners around the outside surface of the first conductor coupling portion. Each of the fingers extends beyond the first conductor coupling portion for engagement with the outside surface of the second conductor coupling portion. The spring loaded adjustment fastener has a threaded stem passing through the finger and the first inner conductor coupling portion. The stem has an adjustable head engaging an outer surface of the finger and a compression spring mounted over the stem to engage the inside surface of the first inner conductor coupling portion. The heads and stems are adjusted relative the compression spring to urge the fingers into locking engagement with the first and second coupling portions. This advantageously results in no substantial increase in electrical clearance required between the inner bus conductors and the outer housing. Further, the heads may be backed off to provide for de-coupling or separation of the joint.
