In this paper we present a new approach of MRAS based on current model only. This technique aims to offsets compensating and solving problems of ordinary MRAS in low speed. Also this new approach allows us to estimate the components of the rotor flux and the rotor speed without using the voltage model. The results of the simulation and the experimental results are presented and show the effectiveness of the proposed technique.
