The paper provides a comprehensive review of the current state-of-the-art in multiphase induction motor drives, highlighting their advantages and recent advancements. Multiphase induction motors offer several benefits over three-phase motors, including higher efficiency, greater fault tolerance, and reduced susceptibility to time-harmonic components in the excitation waveform. The authors discuss the modeling of multiphase induction machines, control strategies such as vector control and direct torque control (DTC), and PWM control of multiphase voltage source inverters. They also explore the design of fault-tolerant strategies and the operation of multiphase multi-motor drives with a single inverter supply. Experimental results from various laboratory rigs are included to support the theoretical discussions. The paper emphasizes the importance of multiphase induction motors in applications like electric ship propulsion, traction, and 'more-electric' aircraft, and addresses the challenges and opportunities in these areas.The paper provides a comprehensive review of the current state-of-the-art in multiphase induction motor drives, highlighting their advantages and recent advancements.
