Abstract: Multi-phase induction machines that contain more than three-phases are becoming popular in many industrial applications, due to the many advantages over three-phase machines such as: reduced line voltage, higher efficiency, lower torque pulsation and density, fault tolerance, stability and lower current ripple. One of the key benefits of multi-phase machines is the additional degrees of control freedom which may be utilized for independent control of single-source multi-motor multiphase drive systems. Another important advantage is their ability to operate under unbalanced conditions. Control of a series-connected five-phase two-motor system using a PI controller is shown in this study. Performance of five-phase two-motor system under a single open-line condition is studied. Results are obtained by simulation in Matlab/Simulink.
