An experimental approach to determine end-parameters for a 2D-FE induction motor model

A method to determine the end parameters required in finite element (FE) models in two dimensions (2D) is presented. The end-winding leakage stator inductance was obtained by measurement of a phase coil out of the stator core. The end ring inductance of the rotor cage was determined analytically and end resistances were obtained by measurements. The FE model is voltage fed, and it was validated against experimental results. Using a FE study, an analysis on the effects of the end-parameters on the main electrical variables (active power, reactive power and line current) of the induction motor is also presented. A three-phase squirrel-induction motor of 0.5 HP, 220 V, 60 Hz was used in this study.
