Squirrel cage induction motor end effects using 2D and 3D finite elements

摘要

The paper describes the calculation of the end effect parameters of squirrel cage induction motors using the finite element method. A two dimensional axisymetric problem definition offers the possibility to analyse the end ring parameters (ring resistance and inductance). Using a three dimensional approach, the correct influence of the bar currents can be taken into account. Furthermore, the three dimensional approach is necessary to calculate the stator end winding inductance and the coupling between end ring and stator end winding.
