Abstract :In this paper multi-phase induction drive with a frequency converter is researched under open phase fault condition. Control strategy of stator voltage phase shift is proposed for dealing with over-currents during steady state. Symmetry of stator current trajectory is achieved. Experiments with six-phase induction motor without a neutral wire under one open phase condition were carried out.
