The purpose of this paper is realizing a rotor-flux-oriented indirect vector controller of an induction motor to compensate the effects of the ironloss generally ignored in the vector controller. Using general ironloss model of induction motor, the vector controller and new decoupling circuit considering ironloss is designed and realized. Also, slip, magnetizing current, stator current and decoupling circuits derived from ironloss model are compared with them from the model not including ironloss and the effects are scrutinized. Finally the total algorithm are realized in 2.2kW servo drive and its effectiveness is verified.
