Abstract—To estimate the efficiency of induction motors (IMs), it is necessary to determine the exact value of the stator windings resistance (SWR). Measuring the SWR of IMs requires opening the IM supply connections, which is very intrusive. Considering that determining the SWR value of in-service IMs should be as non-intrusive as possible, various methods have been introduced in the literature to estimate the SWR of IMs. Therefore, according to the necessity of determining the SWR value in the in-service IMs in a non-intrusive way, in this article, different methods of determining SWR are introduced and reviewed. In the following, by comparing the existing methods of estimating the SWR value in terms of accuracy and intrusiveness, the most suitable method for estimating the SWR value in the in-service is introduced. The effectiveness of the chosen method is verified by the simulation of a 4 kW IM in MATLAB software and by comparing the results obtained from the SWR estimation by the chosen method and the actual SWR value.
