In this paper a comprehensive method is proposed for the electrical parameters estimation of three phase induction machines (IMs) at standstill condition. All the electrical parameters of IMs with high accuracy are extracted at standstill condition by employing the proposed estimation technique. This method is comprised of four steps. In the first and second steps, the stator resistance and the leakage reactance are estimated, respectively. The third step is related to rotor time constant estimation and the magnetizing inductance is estimated in the last step. The estimation process is based on the Γ-inverse model of IMs. Based on the estimated parameters, all of the parameters of the conventional d-q model of IMs are also calculated. The functionality of the proposed method is verified through multiple simulations executed for several IMs with different power ratings. Implementing this method can significantly improve the functionality of various IM drive systems, especially those based on the electrical model of machine.
