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 mounting fixture for positioning a workpiece in a desired relationship with an apparatus including an articulation joint for coupling first and second tubular members in a desired angular relationship. The articulation joint includes a first end portion clamped to an interior surface of the first tubular member and a second end portion clamped to an interior surface of the second tubular member. First and second clamping members of the articulation joint are clamped together to prevent pivotable movement between a first articulation member and a second articulation member of the articulation joint.

摘要： A monitoring apparatus configured for monitoring a carbon brush of a brush holder assembly of an electrical machine. The monitoring apparatus may include a flexible sensor and a signal processing circuit for processing a signal received from the flexible sensor. The flexible sensor may have an electrical resistance that varies based on a radius of curvature of the flexible sensor, wherein the radius of curvature of the flexible sensor may be associated with a deflection of a spring providing a force to engage the carbon brush with a rotating component of the electrical machine. The signal processing circuit may be coupled to the sensor and may be configured to determine a measure of a wear state of the carbon brush using information about the variable resistance of the flexible sensor.

摘要： A brush lead guide for a brush holder assembly configured to retain the leads extending from a brush in a desired position/orientation to ensure the leads do not interfere with movement of the brush within the brush holder. In some instances, the lead guide includes a first guide rail including a channel for receiving a first lead of the brush and a second guide rail including a channel for receiving a second lead from the brush. The lead guide maintains the leads in a position such that the leads are held within the width of the opening of the brush holder to ensure the leads do not interfere with movement of the brush within the brush holder during use of the brush holder assembly.

摘要： Methods and systems for monitoring a brush holder assembly and/or detecting wear of a brush in a brush holder assembly are disclosed. One method includes sending data from a plurality of remote monitoring locations to a central control unit, where the data may be evaluated in order to monitor states of brushes at a plurality of remote electrical facilities. For example, multiple images of a marker tracking longitudinal movement of the brush may be acquired. A comparison of the images, for example, a comparative imaging technique, such as pixel-by-pixel comparison, may then be performed in order to evaluate a condition of the brush, such as the wear rate, wear state, or life expectancy of the brush.

摘要： A brush assembly for use in a brush holder assembly of an electrical machine is disclosed. The brush assembly includes a carbon brush, an electrically conductive terminal and an electrically conductive lead assembly attached to both the carbon brush and the electrically conductive terminal. In some instances, the electrically conductive lead assembly includes a spliced union located between the electrically conductive terminal and the carbon brush and spaced away from both the electrically conductive terminal and the carbon brush. In some instances, the electrically conductive terminal includes an inner core layer positioned between a first conductive metal layer and a second conductive metal layer.
