Fault-Tolerant Operation of Wound Field Synchronous Machine Using Coil Switching
IEEE Access, 2019 This paper proposes a fault tolerant operation of a wound field synchronous machine (WFSM) under the loss of excitation (LOE) fault in the rotor field winding. A two-mode field excitation scheme is presented, where the rotor of the WFSM was modified, and

Improved rotor position estimation in extended back-EMF based sensorless PM brushless AC drives with magnetic saliency [PDF]
, 2007 An improved extended back-EMF based sensorless control method is proposed for a brushless AC motor equipped with an interior permanent magnet rotor. It accounts for dq-axis cross-coupling magnetic saturation by introducing an apparent mutual winding ...

Monitoring the technical condition of the rotor winding turbogenerator
Известия высших учебных заведений: Проблемы энергетики, 2017 Such damage as turn-to-turn short-circuits in turbogenerator rotor winding is one of the difficult revealed types of damage nowadays. Thus protection against interturn insulation of a rotor winding damage in turbogenerators isn't established.
