The paper deals with the diagnostic problems of the converter-fed induction motors in the case of stator faults. For diagnostic purposes the neural detector was developed trained and tested using measurement data of negative components of the stator current and impedance, for different levels of stator failures, load torque and converter frequencies.(More)
The paper deals with the application of the Extended Kalman Filter and the Extended Luenberger Observer algorithms for the stator and rotor fault detection of the induction motor fed by PWM inverter. The induction motor conditions are analyzed using estimated rotor and stator-winding resistance. Mathematical models of the extended state estimators are(More)
