Abstract

This work addresses the issue of the accuracy with which the stator end winding inductance of A.C. machines is determined in the design stage. Only two-layer windings having a shortened pitch are treated in this paper. The end winding inductance was calculated by determining the distribution of the magnetic field, performing numerical analyses based on finite elements method (FEM).The manner of how the inductances are determined using the analysis results is described in the paper. For validating the procedure, comparisons between FEM results and laboratory tests were performed in case of one of the studied machine. There is a very good correlation between the results. Then, a comparative FEM-Analytical study was carried out. Own program was used to design and build the models necessary in the study. Based on about 130 models, some important conclusions have been depicted.
