This paper introduces an alternative tool for stator current envelope extraction in induction motors (IMs) aiming for identifying broken rotor bar (BRB). A new timedomain signal processing algorithm using second order generalized integrator-adaptive notch filter (SOGI-ANF) is introduced for online extraction of both steady state and transient envelopes. The adaptive nature and the structural simplicity...

This paper aims to investigate stator winding insulation failure (SWIF) in induction motors. The location of the SWIF is considered as a new factor that affects the diagnosis of the stator winding short circuit faults. In case of small rating IMs, removing the whole stator winding is done during maintenance program. However, this is not economical and reasonable for large rating induction motors whilst...
