دانلود Skin effect experimental validations of induction motor squirrel cage parameters

Abstract

The  paper  deals  with  the  experimental  validations of  the  corrective  coefficient  used  to  take  into  account  the  skin effect in the equivalent circuit rotor resistance of induction motors with squirrel cages. Locked rotor tests have been performed  at  several  supply  frequencies  on  different  induction motors; the collected experimental data have been used to validate  the  rotor  parameters  analytical  estimation  obtained  by means a numerical procedure previously proposed by the authors.  The  reported  comparison  between  experimental  and  calculated  skin  effect  corrective  coefficients  shows  that  the  adopted  model  allows to get satisfactory results in terms of accuracy, taking into account the objective difficulties to estimate the rotor parameters from the experimental tests.
