A New Offline Method for Stator Inductance Detection for Use in Induction Motor Controllers

摘要

This paper describes a novel approach for stator leakage inductance measurement that can be used for self tuning. Contrary to many existing methods this method is not prone to noise and leads to accurate measurements. The paper briefly describes the theory behind the approach. The method is 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.
