Abstract
The structure of variable-frequency induction motor electric drive with scalar control, which allows to get increased dynamic properties, have been proposed. System has active and reactive components of stator flux vector, torque and speed control loops. The system permits to get the stabilization of stator flux vector’s magnitude, and improved quality characteristics in transients. The study of system has been carried out by mathematical modeling method.
