摘　　要：根据双 Y 移 30 °六相异步电机的结构，详细分析了其数学模型，并利用仿真工具 Matlab/Simulink 完成电机本体建模；基于旋转坐标系下的双 Y 移 30 °六相异步电机数学模型，采用基于定子电流解耦角的分析方法，得出定子角频率与定子电流解耦角关系，电机进入弱磁区后定子电流励磁分量与转矩分量和定子电流解耦角的关系，从而设计了基于电压调节器的六相异步电机的弱磁控制策略并搭建了相应的仿真模型；仿真结果表明，所提出的六相异步电机弱磁控制策略动态性能良好，实现了六相异步电机在恒转矩和恒功率范围内的全速运行，满足系统设计要求，为六相异步电机弱磁控制的应用提供了参考依据。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.
