Multiphase machines have been recognized in the last few years like an attractive alterna‐ tive to conventional three-phase ones. This is due to their usefulness in a niche of applica‐ tions where the reduction in the total power per phase and, mainly, the high overall system reliability and the ability of using the multiphase machine in faulty conditions are required. Electric vehicle and rail...

A new approach to fault analysis is presented. We consider multiple stuck-at-0/1 faults at the gate level. First, a fault collapsing phase is applied to the network, so that equivalent faults are eliminated. During the analysis we consider frontier faults where there is at least a normal path from each faulty line to a primary output. It is shown that the set of frontier faults is equivalent to...

Speed sensorless vector control of 3-phase induction motor under open-phase fault (faulty 3phase induction motor) based on Indirect Rotor Field-Oriented Control (IRFOC) is proposed in this paper. To ensure high performance FOC of induction motor drives, the estimation of the rotor speed is necessary. However, the algorithm used to estimate the rotor speed for a 3-phase induction motor cannot be...
