  • Patent number: 11940776
    Abstract: A system is provided that predicts motor wear and failures before they occur. Telemetry data from motors in a motor application is collected and predictive algorithms are used to determine when a motor is aging and when it may fail. Identifying a potential failure in these types of applications can help mitigate risk of other equipment failures and realize cost savings. In one example, a motor aging detection system is provided that includes one or more DC motors, and a motor controller coupled to each motor. The motor controller reads three phase currents from each motor and converts the phase currents to digital values, calculates telemetry data including applied voltages, back electric-motive force, inductance, and resistance of each motor at periodic intervals, stores this telemetry data for each motor in a memory. An age detection circuit retrieves this information from the memory and determines age factors of the motor.
