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.

Health monitor for an electric machine

A control system for a cooling system configured to selectively operate one or both of a condenser fan an evaporator fan in a reverse direction RD, measure power draw at the motor against configuration data and fan motor profiles, and determine if a blockage has occurred before the static pressure has reached a critical point static pressure where the efficiency, performance, and cooling capability of the cooling system is hindered and maintenance is required to clear the blockage. By determining if blockage has occurred before the static pressure has reached the critical point static pressure, an alert or corrective action can be taken.
