DTC in a nutshell Direct torque control, DTC, is a motor control method famous for its superior dynamic properties. Less known is the fact that DTC optimally utilizes the switching frequency to achieve the target: regulation of torque and flux within specified hysteresis band. Thus, DTC contributes to a high Read more
Scalar control – What does it actually mean? Many times we see that the term ‘scalar control’ is used in incorrect way or being misinterpreted. In this article we will briefly discuss scalar control – what does it actually mean? How does it differ from a field oriented control? What Read more
