Direct Torque Control (DTC) scheme uses the stator resistance of the machine for the estimation of stator flux. The variation of stator resistance, due to stator winding turn fault, creates an error in the estimated stator flux position that may subsequently cause a failure of the complete drive system. This paper proposes the possibility of developing a remedial operating strategy using artificial...
This paper proposes an effective approach to detect, isolate, and identify fault severity and post fault operation of permanent magnet synchronous motors (PMSM) in the presence of stator winding turn fault. The paper proposes fault tolerant operation of PMSM under post condition with stator winding turn fault by using grounded neutral point through controllable impedance using artificial neural network...
Permanent magnet synchronous motor (PMSM) is currently the most attractive application electric machine for several industrial applications. It has obtained widespread application in motor drives in recent time. However, different types of faults are unavoidable in such motors. This paper focuses on stator winding faults diagnosis. This paper proposes the ratio of third harmonic to fundamental FFT...
Multi-phase motor drive system are increasingly used due to their inherent advantages. Several topologies are investigated in the literature for multi-phase drive system. The most popular among them are five-phase and six-phase. In six-phase system two topologies exist. In one topology, the windings or phases are 60 degrees apart and called symmetrical six-phase system. The second topology has two...
