This paper suggests a distinct method having advantages over classical MCSA and Stray flux analysis techniques. The radial flux sensing coil (RFSC) proposed in this study provides the wanted ease of stator turn fault (STF) detection and simplicity of implementation. The RFSC has been found to be more effective compared to external flux sensors and current sensors for detection of unbalanced source...
This paper proposes a stator winding fault diagnosis for interior permanent magnet (PM) machines based on the pulsating-type voltage injection. By superimposing a pulsating voltage on d-axis with respect to the rotor-referred synchronous frame, measurable winding fault reflected signals occur in the injection induced current ripples. Comparing to prior diagnostic techniques, the proposed injection...
