    Abstract: This study deals with the reliability of the five-phase induction motor drive in vector control. Regarding the three-phase induction motor if one phase of the motor or inverter were opened, a divided DC bus and neutral connections would be required so that the currents in the other 2 phases are controlled independently. By the above a zero sequence component is necessary in a three-phase induction motor to provide an undisturbed rotation after one phase is opened. But in the 5-phase drive the event of losing 1 or 2 legs of the inverter or motor phases, the 5-phase  induction  motor  an  operate  continuously  and  steadily  with the remaining four phase or three phase connections. Simulation is done in MATLAB and results are attached.
