The speed-sensorless vector control and the identification of motor parameters in this paper are the two novel research of vector control.Using asynchronous machine's mathematic model in three-phase static reference frame, this paper has derived it's mathematic model in two-phase static reference frameand in two-phase rotating reference frame, and got the coordinate transformance formulus based on the constant magnetic force and power force, by compared different field orientation methods, we can find that field orientation at rotor field can realize the decoupling of the stator current flux component

无速度传感器矢量控制和电机参数辨识是矢量控制的两个新的研究方向，本文利用异步电机在三相静止坐标系下的数学模型推导出两相静止坐标系、两相同步旋转坐标系下的数学模型，根据磁动势守恒和功率守恒的原则，得出各坐标变换公式；通过不同磁场定向方式的比较发现，异步电机按转子磁场定向时定子电流励磁分量和转矩分量可以比较方便地实现解耦。

Common rolling plank is shown intense (orientaton of 0002) tool reference plane, after rolling of horn waiting for diameter, plank grain orientaton by original (change of orientaton of 0002) tool reference plane is; of orientaton of blame tool reference plane the existence after strain crack of common rolling plank is many twin brilliant, amount of brilliant of twin of drawing of direction of rolling of edge of plank of rolling of horn w

普通轧制板材呈强烈的(0002)基面取向，等径角轧制后，板材晶粒取向由原来的(0002)基面取向转变为非基面取向；普通轧制板材拉伸断裂后存在大量孪晶，等径角轧制板材沿轧制方向拉伸孪晶数量明显减少，等径角轧制有可能启动了新的滑移系，而拉伸孪生只是作为一种协调变形机制。
