    Abstract: A health monitor circuit for an electric machine includes a plurality of sensors, a rectifier, a memory device, and a microprocessor. The plurality of sensors includes a current transformer configured to be electromagnetically coupled to an electrical conductor that feeds a stator winding of the electric machine. The rectifier is coupled to the current transformer and is configured to convert an AC signal generated by the current transformer to a DC signal to supply power for the health monitor circuit. The microprocessor is coupled to the memory device and the plurality of sensors. The microprocessor is configured to periodically collect a stator current measurement from the current transformer and write the stator current measurement to the memory device.

    Abstract: A health monitor circuit for an electric machine is described. The health monitor circuit includes at least one sensor configured to measure a parameter of the electric machine, a communication interface, and a microprocessor coupled to the at least one sensor, the communication interface, and a memory. The microprocessor is configured to periodically collect time samples of the parameter measured by the at least one sensor, transmit factors of the time samples to the memory, and perform a high resolution fast-Fourier transform (FFT) on the factors. The microprocessor is also configured to extrapolate results of the high resolution FFT to a produce a high resolution frequency domain waveform, filter the high resolution frequency domain waveform by a parameter, and transmit, via the communication interface, the filtered frequency domain waveform to a remote system for further processing.
