The equivalent circuit of an induction machine (IM) without regard to iron loss would lead not only significant mismatch between simulation and experimental results but also deteriorate the vector control performance. This study focuses on modifying the indirect rotor flux-oriented controller subject to the IM equivalent circuit with consideration of stator and rotor core losses. An analytical approach based on the core-loss model for estimating the rotor slip shows salient impact of the stator and rotor core loss on IM performance. A 10 HP IM is performed for laboratory test. The experimental and simulation results validate that the modified vector controller is superior to the conventional vector controller in both transient and steady-state responses.
