This paper presents a new method to establish the leakage inductances of AC machine stator winding using a numerical analyzing program based on the finite elements method. The 3D numerical analysis is used to determine the end winding leakage inductance. In order to eliminate the magnetic flux present in the space normally occupied by the rotor, when the rotor is removed, the air from the rotor space is replaced with a very low relative magnetic permeability (10-6) material. The results obtained are compared to those obtained by another method of numerical analysis, and with those calculated analytically. For one of the models, the results are compared to the results obtained experimentally as well.
