摘要： A brush holder assembly for use in an electrical generator having a moving conductive surface may include a brush holder, such as a brush box, that is configured to be removably mounted to a mounting element on the electrical generator. A carbon brush may be slidingly disposed with the brush holder and may be biased into sliding contact with the moving conductive surface. The brush holder assembly includes a handle that is moveable between an unlocked position in which the brush holder is removable from the mounting element and a locked position in which the brush holder is secured relative to the mounting element. A circuit board is disposed within the handle and includes a sensor that provides an indication of an occurrence of an anomalous and/or threshold condition of the carbon brush.

摘要： A shaft grounding and monitoring system may include a grounding member slidingly engageable with a rotating shaft. An electrical sensor may be configured to be coupled with the grounding member in order to detect an electrical parameter that provides an indication of electricity flowing from the rotating shaft to ground through the grounding member. A processor may be operably coupled with the electrical sensor and may receive and analyze data from the electrical sensor at multiple sampling points taken at different rotational positions of the rotating shaft during multiple revolutions of the rotating shaft. The processor may be configured to develop, over time, a reconstructed waveform representing a compilation of the periodically sampled values of the data from the electrical sensor through one revolution of the rotating shaft.

摘要： Example brush holder assemblies of an electric machine are disclosed. An example brush holder assembly of an electric machine includes a carbon brush including an upper surface and a lower surface opposite the upper surface. The brush holder assembly also includes one or more lead wires extending out of the carbon brush at an insertion point on the upper surface and a first cavity extending into the carbon brush from the upper surface at a location spaced away from the insertion point of the one or more lead wires and unobstructed by the one or more lead wires.

摘要： A system for monitoring the wear state of a carbon brush of a brush holder assembly in which the length of the carbon brush is diminished from an initial length as an end of the carbon brush wears away during use. The system includes a wear state monitor, including a sensor, coupled to the carbon brush. The wear state monitor is configured to rotate as the length of the carbon brush diminishes. The sensor is configured to measure an angular displacement of the wear state monitor as the wear state monitor rotates. The measured angular displacement of the wear state monitor correlates to an amount of diminution in the length of the carbon brush.
