Abstract: An induction machine short circuit stop is interposed between a brace and a machine component, such as a generator building bolt, in order to limit component motion during a short circuit event. The stop is a block of resilient non-conductive material that is oriented proximal the machine component at a desired spaced gap. Gap dimensions may be modified by use of different height stop blocks and/or shims. The stop is affixed to the brace by straps, cordage or fasteners, such as threaded studs. The stop is suitable for retrofitting existing induction machines in the field or in refurbishing service centers.

Abstract: An electrical machine may include a plurality of stator coil ends each having a fluid passageway therein. The electrical machine may further include a plurality of rings and a plurality of axial connector assemblies for connecting the plurality of stator coil ends to the plurality of rings. Each axial connector assembly may include a header cap including an open end received on a respective stator coil end and a closed end opposite the open end, the closed end defining a coil spherical connector portion. The header cap may have a fluid port therein coupled to the fluid passageway of the respective stator coil end. A ring spherical connector portion may be carried by a respective ring, and a pair of connector members may receive therebetween the coil and ring spherical connector potions.

Abstract: A brush holder (100) for carrying a brush (102) and for providing adjustment of the brush relative to the commutator (104) of a dynamoelectric machine (105). The brush holder provides for adjustment of the gap (110) between the commutator and the brush, and for adjustment of the brush in the axial direction along the commutator. The brush holder also locks the brush at the desired position for operation in the dynamoelectric machine.

Abstract: A rotor winding series connector 40a is for a dynamoelectric machine, such as an exciter 25 of a generator apparatus 20 including a rotor 32 and a stator 34 surrounding the rotor. The rotor 32 may include rotor windings defining at least one pair of first and second rotor winding ends 38a, 39a arranged in spaced relation. The rotor winding series connector 40a may include a C-shaped connector body 42a including a medial connector portion 44a and respective first and second end connector portions 46a, 47a extending outwardly therefrom. The rotor winding series connector 40a may further include first and second connector brackets 48a, 49a carried by the respective first and second end connector portions 46a, 47a for receiving the respective first and second rotor winding ends 38a, 39a therein.
