This paper presents an application of rotor field oriented control (RFOC) to a five-phase induction motor with the combined fundamental and third harmonic currents. Based on the motor model developed in a new d/sub 1/q/sub 1/d/sub 3/q/sub 3/n reference frame, the complete theory and modeling of rotor field oriented control of the five-phase induction motor are established. Specifically, investigation is made to improve power density and output torque of the five-phase induction motor by injecting third harmonic currents. By the proper dynamical adjustment and steady state compensation, the rotor field oriented control of the five-phase induction motor not only achieves a high drive performance, but also controls the fundamental and third harmonic flux and torque to generate the desired nearly rectangular air-gap flux. Both simulation and experimental results further verify the theoretical analysis and demonstrate the feasibility and practical value of the proposed five-phase induction motor drive.
