This paper provides an improvement in sensorless control of induction machines (IM). The proposed method uses a reduced-order linear observer that simplifies design and hardware implementation. Its execution time is less than that we realized in the previous works. Furthermore, it also estimates load torque. We have obtained good results until 60 rpm. The simulation and experimental results illustrate the validity and efficiency of the proposed method.
