Abstract :
This paper provides a manner for calculating the equivalent circuit parameters of a three-phase squirrel cage rotor type induction motor. All the electrical parameters of stator and rotor have been calculated. The core and magnetizing losses also determined in order to calculate the magnetizing circuit parameters. A 2-dimensional induction motor has been used in the simulation. Two types of non-linear finite element methods have been included in current paper. The first is the magneto static analysis to determine the self and mutual inductances of both stator and rotor parts. The second technique is the time stepping transient analysis for calculating the dynamic performance parameters (electromagnetic torque, speed and the rotor current variation due to skin effect). The magnetizing reactance and core resistance are also calculated based on. The model has been built and simulated using a 3-phase, 18.5 Kw, star-connected induction motor. ANSYS software has been used in the simulation. The parameters that have been obtained are compared with experimental results to validate the model.
