The paper deals with the problem of determining the stator end winding inductance of A.C. machines. It refers to the two-layer windings with shortened pitch, the relative pitch being less than one. The inductance has been determined by numerical analysis based on finite elements method (FEM), the procedure being described in this paper. In order to validate the procedure, a comparison between FEM results and laboratory tests has been made for one of the modelled machine. The results have been very close. After that, a comparative FEM-Analytical study was performed. It was used its own program to design and realize the numerical models needed for the study. Also, in the design phase of the models, the end winding inductance has been determined, with analytically relations used in the literature, by the same program. Based on more than 130 models, with different types of windings, some important conclusions have been depicted.
