Estimation of stator winding temperature of a three-phase induction motor

Abstract EN

This paper adopted a thermal network method (TNM) based on Motor-CAD with MATLAB/Simulink software, and finite element method (FEM) based on motor- cad with flux2d software, to estimate the stator winding temperature of a totally enclosed fan-cooled (TEFC), squirrel cage, three-phase induction motor.

the three software packages were adopted successfully with a good agreement among their results resulting in preferring using motor-cad in obtaining results, and using flux2d with MATLAB to validate these results.

the success of triple-software methodology will give the induction motor designer a well-validated tool in attaining a safe motor operation without exceeding the maximum allowable stator winding temperature rise, and without using an experimental test based on an expensive manufacturing motor.
