Abstract— Accurate identification of motor electrical parameters is essential for stability and performance optimization, fault detection, maintenance, and reliable commissioning of electric motors, as inaccurate identification of electrical parameters prior to commissioning may cause severe damage to the electric motor. Therefore, finding the optimal method for estimating motor electrical parameters is of high importance. In this paper, a comparison of offline stator resistance estimation methods using signal injection via a voltage source inverter is investigated and analyzed. Generally, these methods can be categorized into four groups, all of which have been simulated in the MATLAB/Simulink environment on a synchronous reluctance motor (SynRM), and their results will ultimately be compared in terms of estimation speed, method complexity, and measurement accuracy under two conditions with and without considering inverter nonlinear effects.
