This paper is introducing a very fast simulation approach to analysis the transient behavior of three-phase squirrel-cage type induction motor. The well known model with four differential equations of voltage and current in rotor reference frame along with the torque equation is used to model the motor. Also, in the proposed model, the saturation of both magnetizing and leakage inductances is considered as function of magnetizing current. The commercial software package, MATLAB, is used to implement the transient behavior of the model. The validation and speed of obtained model is tested and compared with Matlab/Simulink conventional model and published papers. The results show that an excellent agreement is obtained demonstrating the accuracy of the proposed model. Also, the simulation speed of the proposed approach is shown an excellent result compared with conventional approaches.
