A Novel Approach to Detection of Some Parameters of Induction Motors

This paper describes a novel approach for offline stator leakage inductance and online stator resistance estimation that can be used for self-tuning of induction motor drives. The paper briefly describes the theory behind the approach. The proposed methods are experimentally tested on an industrial induction motor and also tested on a washing machine motor designed for variable speed operation. Test results are given and the robustness of the approach is illustrated.
