异步电机控制矢量控制中，需要磁链保持不变，根据电机的额定值计算磁链的额定值的程序代码，可以为电机控制的作为参考。-Induction motor control vector control, the need to maintain constant flux, flux is calculated according to the rating of the motor rated program code for motor control as a reference.

直接转矩控制，异步电机，磁链计算，控制电机的正反转(Direct torque control, asynchronous motor, flux calculation, positive and negative control of the motor)
