REAL TIME MONITORING OF ROTOR OR STATOR SHAPE CHANGE FOR ROTATING MACHINES
First Claim
1. A monitoring system for a rotating machine including a stator and a rotor, comprising:
- at least one gap measuring sensor affixed on the stator at a sensor position, said sensor producing real time measurements of gap thickness for each passing rotor reference point and associating said real time measurements to a unique identifier for each rotor reference point;
a memory for storing reference values of gap thickness for each rotor reference point and each sensor position;
a comparator for comparing corresponding ones of said real time measurements and said references values and identifying a positive or negative variation in said gap thickness greater than a predetermined minimum percentage; and
a warning signal generator for emitting at least one warning signal upon said identifying, wherein said warning signal is a notification of at least one change in the shape of the rotor and/or of the stator.

Abstract
A monitoring system for rotor or stator shape changes detection of a rotating machine which can be used with an electric rotating machine with salient pole rotor. The system comprising: at least one gap measuring sensor affixed on the stator and producing real time measurements of gap thickness for each passing rotor reference point and associating the real time measurements to a unique identifier for each rotor reference point; a memory for storing reference values of gap thickness for each rotor reference point and each sensor position; a comparator for comparing corresponding ones of the real time measurements and the references values and identifying a positive or negative variation in the gap thickness greater than a predetermined minimum percentage; and a warning signal generator for emitting at least one warning signal.
