Abstract Based on the basic principle of the hexagonal space voltage vector, a starting control method of induction motor with high starting torque is proposed. Firstly, the principle of realizing discrete frequency conversion by using hexagonal space voltage vector on the power frequency sine grid is analyzed, and its feasibility from rotor rotating flux track is proved. Then, the unattenuated flux in the current interrupted time of space voltage vector frequency conversion is illustrated by using the characteristic of high power induction motor, the multilevel discrete variable frequency based on hexagonal phase space voltage vector is realized through the translation of the voltage vector. The impact of the frequency switching process is minimized by using a specific frequency switching mode, the purpose of discrete frequency conversion without interference is almost achieved. Lastly, through the comparison between the simulation and the measured results, the effectiveness of the proposed method is verified. The purpose of reducing starting current and improving torque is reached, having certain theoretical research and practical application value.

Key words： Discrete variable frequency rotor flux high starting torque space voltage vector induction motor
