Permanent Magnets Synchronous Machines Fault Detection and Identification
Résumé
The reported work is the design of a Fault Detection system for permanent magnet synchronous machines (PMSM). Two main faults occurring on these machines are identified as inter-turns short-circuits and rotor single pole demagnetization, and characterized. An analytical model of the PMSM is developed and simulated using Matlab Simulink. The model enables simulating nominal and faulty PMSM behavior, with several stages of degradation, and is supported by tests results. 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. An application is made on a 9-slots 8-poles synchronous machine being popular in aeronautics.
