Abstract:
Studies in the field of condition monitoring and fault
diagnoses of induction motors demand suitable models to
analyse internal fault conditions of the machine. An
implementation of detailed multiple coupled circuit
based model of three phase squirrel cage induction motor
with m-stator circuits and n-rotor bars in
MATLAB/SIMULINK® platform is presented. The model
parameters are calculated based on geometry and winding
layout of the ac machine. The transient and steady state
behaviour of the machine for symmetric and asymmetric
operating conditions are analysed. The simulation
results in both time and frequency domain are presented.
Behavioural study of induction motors under various
faulty situations through asymmetric machine modelling
supports in signature extractions for online condition
monitoring.
