1. A power meter comprising:

  • a housing;

    a plurality of sensors configured to monitor operation of a motor;

    a processor disposed within the housing and configured to receive operational feedback from the plurality of sensors and proactively determine an operational wellness of the motor from the operational feedback;

    wherein the processor is further configured to generate baseline data from the operational feedback during known healthy operation of the motor; and

    wherein the processor is further configured to perform a fast Fourier Transform (FFT) on the operational feedback to compare a frequency spectrum of the operational feedback to the baseline data to determine the operational wellness of the motor.
