Abstract :
Stator core loss has significant adverse effects when an induction motor is controlled by the conventional field-oriented method. So, taking core loss into account should make it possible to control the torque very precisely. In this study, a direct-field-oriented induction motor with a deadbeat rotor flux controller was developed. The method ensures maximum efficiency in the steady state without degradation of the dynamic response. Simulation and experimental results have demonstrated that this method has higher efficiency and good speed response without any degradation in the transient characteristics
