Abstract : The reported work is the design of a Fault Detection and Isolation system for an innovative 12-slots 10-poles synchronous machine that becomes more and more popular in aeronautics. Two main faults occurring on this machine are identified as inter-turns short-circuit and rotor single pole demagnetization, and characterized. An analytical model of the motor is developped using Matlab Simulink. This model allows simulating nominal and faulty motor behaviour. It is parameterizable and is able to simulate several stages of degradation. Specific indicators are proposed for each fault. They do not require additional material or sensors since they are based on the signals already monitored for the machine control. Inter-turns short-circuit and pole demagnetization are successfully detected and identified.
