Detection and Identification of Demagnetization in PM Generators During Transient Conditions

Demagnetization Monitoring and Identification in PM Generators With Concentrated Windings During Transient Conditions

“…Aiming to answer those needs, this paper which is the continuation of the early work [32], investigates the use of the stator current for condition monitoring during transient operation of PM generators. Firstly, analytical calculations will demonstrate the expected higher harmonics as a function of the machines' stator coils and numbers of poles.…”
