The mathematical model of the six-phase induction motor with double Y shifted 30 ° is analyzed and the simulation model is built up in Matlab/Simulink. After defining the stator current decoupling angle, the relationship of the stator angle frequency and the stator current decoupling angle is obtained. When considering that the motor is in flux weakening area, the relationship of the excitation component of stator currents and stator current decoupling angle, the relationship of the torque component of stator currents and stator current decoupling angle are obtained respectively in the rotating reference frame. Thereafter the flux weakening control strategy based on voltage regulation is implemented. The simulation results show that the dynamic performance of the flux weakening control strategy presented in this paper is good enough to meet the requirement of the system. Therefore the six-phase induction motor operates in good condition in both the constant torque and constant power areas. Therefore, the research results have referential value to such sites where the six-phase induction motor flux weakening control is needed.
