Vektorregelung

Vector control (field-oriented control) is a high-performance control type for induc-

tion machines. It is based on an exact model calculation of the motor and two cur-

rent components that simulate and accurately control the flux and torque by means

of software algorithms, thereby enabling predefined speeds and torques to be ob-

served and limited accurately and with a good dynamic response.

Two vector control types exist:

The frequency control (–> "Sensorless vector control") and the speed-torque con-

trol with speed feedback (–> "Encoder").
