Abstract :
In this paper a novel detection method for fast detection of stator turn fault for a 5-phase surface mounted permanent magnet (SPM) machine is proposed. The detector is based on online extraction of residual current sequence components using a model based approach. The detector is shown in simulation to be robust to load and speed disturbances. In addition, the method also identifies the faulted phase which is needed for fault mitigation methods to be effective.
