Space vector control according as ac induction motor two - axis theory speed separates the stator current into two components . one is the torque component ; the other is the flux component . a structure similar a dc machine structure where torque and field can be controlled independently is given 矢量变换控制是以交流电动机的双轴理论为依据，在同步旋转坐标系中把定子电流矢量分解为两个分量：一个分量与转子磁链矢量重合，称为励磁电流分量；另一个分量与转子磁链矢量垂直，称为转矩电流分量。
