With distinct advantages over three-phase machines, multiphase machines are gaining increasing popularity in ship electric propulsion applications. Many fault-tolerant control strategies have been proposed for multiphase drive to suppress the torque ripples under faulty conditions; however, most of them depend heavily on the mathematical models and the need of the prefault to postfault transitions,...
Two fifteen-phase induction motors fixed on a single shaft is used in a ship propulsion system, and drive system of fixed joint motors with propeller load is studied in this paper. Fifteen-phase induction motor and propeller load are analyzed and modeled. Vector control system is designed, which can regulate the power allocation between two motors. Two working conditions of the ship are studied, and...
