First Claim
Patent Images
1. A method for detecting a departure from normal operation of an electric motor, comprising:
- modelling a set of normal current measurements for a motor being monitored;
modelling a set of operational current measurements for said motor being monitored, wherein said modelling is carried out by a neural network auto-associator which is trained to reproduce its inputs on its output;
indicating a potential failure whenever said set of normal current measurements and said set of operational current measurements differ by more than a predetermined criterion.

Abstract
A method for detecting a departure from normal operation of an electric motor comprises the steps of modelling a set of normal current measurements and a set of operational current measurements for the motor being monitored. The modelling is carried out by a neural network auto-associator which is trained to reproduce its inputs on its output. A potential failure is indicated whenever the set of normal current measurements and the set of operational current measurements differ by more than a predetermined criterion.
