Study of current space phasor trajectory of the three-phase asynchronous motor with one phase open circuit fault

The presented paper deals with the calculation of space phasor trajectory of the magnetization current of induction machine supplied by a converter under open-phase fault. To explore possibilities to reduce the impact of failure on the function of the machine is a winding node connected to zero point. Under open phase fault it is another possibility to improve behavior of the two-phase operation. There is still to apply a circular rotating magnetic field to the machine by imposing a 60o phase shift between the stator currents of the two supplied stator windings.
