Successful cases

Asynchronous Motor Vector Control System

Variable frequency and speed regulation technique has benefits of wide speed control range, high precision and good dynamic response. This case shows the magnetic field oriented based vector control method of a three-phase AC asynchronous motor. The field excitation components and torque components of the stator current are separated using coordinate transformation, and then the motor speed and flux can be decoupled and controlled independently.
