  • Brush wear indicator
    Patent number: 4528557
    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.
