This paper deals with the diagnosis of the electrical faults of induction motor operating under the direct field-oriented control. Two different faults are taken into account: stator winding inter-turn short circuit and voltage source inverter transistor damage. The fault diagnostic algorithms are described. Performance of both algorithms is validated in presence of the different kind of damages....
This paper deals with monitoring and diagnosis of stator windings damages in vector-controlled induction motor (IM) drive. The article proposes a simple method of shorted turns detection using only virtual control and decoupling signals from the classical Direct Field Oriented Control (DFOC) method. The diagnosis of the stator windings faults is based on the analysis of twice the fundamental frequency...
