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.
