Abstract: An apparatus for detecting the wear of a motor brush includes a spring that biases the brush towards an extended position. A portion of the spring moves along a path towards the extended position as the brush wears, wherein the spring portion makes mechanical contact with a portion of an electrical signal generating device that is disposed in the path to indicate a given amount of brush wear has occurred.

Abstract: A motor brush wear indicator includes a probe embedded in a brush and connected in the primary circuit of a transformer for completing the secondary circuit when the brush has worn to a predetermined degree. An oscilator is coupled to the secondary of the transformer which in turn is connected to the gate of an SCR for providing a gate signal when the primary circuit is completed. A relay is connected to the anode-cathode circuit of the SCR for operating an indicating device when the SCR becomes conductive.

Abstract: A brush wear indicator for a dynamoelectric machine including a brush holder for slidably mounting a brush, a self-winding, brush-biasing spring having one of its ends mounted in fixed relationship on the brush holder, in combination with a circuit board having a dielectric member on which a plurality of electrical contacts are mounted in spaced relationship to be electrically engaged by the spring when it is fully extended to accept a new brush in the brush holder. As the brush wears, the spring moves downward to continue exerting a biasing force on the brush, and sequentially moves out of engagement with the contacts on the circuit board responsive to predetermined degrees of brush wear occurring. Such movement of the spring causes the contacts to be sequentially disengaged from the spring, thereby causing associated signal means, such as glow lamps, to be de-energized thus indicating the occurrence of the predetermined degrees of brush wear.

Abstract: A dynamoelectric machine (1), having brushes which contact an armature contact surface such as commutator (6) or slip rings, is provided with a plurality of independent, individually removable brush holders (10, 100). Each brush holder is provided with either a removable pin (102) to allow brushes to contact the armature contact surface after the brush holder (10, 100) has been installed, or with a clamping bolt (40), retaining brushes (8) in a predetermined position for insertion of the brush holder, and removal of the brush holder, the brush holder being tilted or cocked to avoid contact between it and the armature contact surface. Bolting the brush holder (10, 100) into place makes electrical contact between the dynamoelectric machine and the brush holder by means of an insulated, conductive threaded aperture (34) on the exterior service of the machine, a mounting bolt (24) inserted into this aperture (34) urging a conductive portion (20) of the brush holder into electrical contact. The brush holder (10, 100) may be further provided with a rotatable spring support (212) for varying the pressure exerted on the brushes, and a measuring scale (216) for correlating the length of partially worn brush with an angular position of the spring support, to facilitate adjustment of brush pressure as brushes wear. Angular adjustment of the position of the spring support may also serve to lift certain types of brushes into a retracted position. The disclosed brush pressure adjustment structure is also usable with non-removable brush holders.

Abstract: An indicator is provided in a dynamoelectric machine such as a DC electric motor wherein brushes are provided in brush holders to cooperate with a rotatable electrical conductor in the machine, for example, slip rings or a commutator. The indicator gives an indication when a brush has worn to a point where it should be replaced, and then an alarm sounds or a light is illuminated. The brush wear indicator includes an indicator contact which is electrically connected to the indicator means and it is insulated from but mounted to move in accordance with the brush wear movement. The contact is provided on the end of an electrical conductor which is embedded in the rear axial end of the brush so that the indicator contact will become exposed and the insulation covering it will be worn away upon sufficient brush wear. This completes an electrical circuit between the indicator contact and the commutator to thus provide an indication at the indicator means.

Abstract: A brush which presses against the commutator of a machine has secured thereto a resilient spring contact element, and as the brush wears, movement thereof causes physical engagement of the resilient spring contact element with another contact element to complete a current path. The latter contact element is secured to a yoke which surrounds the commutator.

Abstract: A brush which presses against the commutator of a direct current machine has a groove in one side thereof into which a fixed probe partially extends. As the brush wears, movement thereof causes physical engagement of the probe with the end of the groove to complete a current path through the probe. Flow through the current path energizes and latches a warning device.
