Abstract
A method of monitoring the operation of a turbomachine includes positioning a flux probe in an operating position with respect to a rotor of the turbomachine, rotating the rotor at an operating speed with respect to a stator to one of generate an electrical output and produce an output torque. The method also includes measuring the passage of each slot of a plurality of slots formed in the rotor using the flux probe, calculating a time duration between the passage of a first slot of the plurality of slots and a second slot of the plurality of slots, and comparing an expected time duration for the operating speed with the calculated time duration. A difference in the comparison is indicative of one of a power change and a torsional vibration condition.
