TY - JOUR T1 - Production of Circular Stator Current Trajectory in Multi-Phase Induction Drive Under Open Phase Fault Condition AU - Pıtrėnas, Aurelijus AU - Uznys, Donatas AU - Beıštaras, Dominykas PY - 2016 DA - February JF - Balkan Journal of Electrical and Computer Engineering PB - MUSA YILMAZ WT - DergiPark SN - 2147-284X SP - 1 EP - 4 VL - 5 IS - 1 LA - en AB - In this paper multi-phase induction drive with afrequency converter is researched under open phase faultcondition. Control strategy of stator voltage phase shift isproposed for dealing with over-currents during steady state.Symmetry of stator current trajectory is achieved. Experimentswith six-phase induction motor without a neutral wire under oneopen phase condition were carried out.
