Abstract

In this study, the speed and torque of a wound rotor induction motor (WRIM) have been controlled by adjusting the rotor resistance using a microcontroller. PI controller has been chosen for the speed control due to its simple structure and higher response time. Realized system has been tested on a 1,5 kW WRIM in a laboratory. Experimental results show that implemented system has been faster, more stable and very sensitive in speed control when compared to classical systems.
