With the development of computer control technology and power electronics, six-phase induction motor control system has been widely used in industrial area due to its advantages. Through the study of single-phase induction motor SVPWM control technology, combined with the six-phase induction motor winding structure, a novel six-phase induction motor SVPWM control strategy is proposed and the third harmonic is injected in the system. The six-phase induction motor was injected into the 10% and 20% third harmonic, by detecting the output current and the harmonic content, the relationship between each other is analyzed. Finally the whole six-phase induction motor control system is realized.
