The advantages of fifteen-phase induction machine drives over three-phase systems are the improved ma chine torque density, reduction of magnetic flux harmonic and better system reliability. Fifteen-phase system can provide continuous system operation in faulted mode following the loss of excitation of one or more stator phases. The paper has proposed the vector control algorithm for a new fifteen-phase induction motor based on the existing researches on muhiphase motor systems. The establishment of a mathematical model for the fifteen-phase induction motor leads to the derivation of a vector control algorithm for the fifteen-phase induction motor and the presentation of the control block diagram of the system. The results of testing the system show that the vector control algorithm is correct and feasible so that it can achieve a good control effect when being applied to the actual fifteen-phase induc-tion motor vector control system. The vector control algorithm can be directly used for the MW-class high-power fif teen-phase induction motor system.
