Building a machine that emulates the electrical fault can be expensive and implies high risk of damage. Different types of fault cannot be created in the same machine. This paper presents a mathematical model and dynamic simulation of 3-Φ squirrel cage induction motor to study the performance of the AC machine. The equations will be derived and developed that will represent the 3-Φ Induction motor. Those equations can be used to study the fault analysis of the winding as well as their

As, Direct Quadrate (d-q) model is superior to abc reference in terms of complexity and computational time, for modelling the drive system, d-q transformation method is used. Then the simulation of the system will be done and analysis of dynamic behaviour of the motor will be studied. Then the torque and speed will be calculated. The study of the transient and steady state analysis of an induction motor model will be performed through the simulation. Magnetizing inductance ( ) can be calculated by using Equation (17 ) = 2 4 This work is licensed under a Creative Commons Attribution 4.0 International License V. CONCLUSION Mathematical model for 3-Φ squirrel cage induction motor has been developed in arbitrary reference frame. Developed model was simulated in MATLAB and its results were compared with conventional model. Comparison was done on the basis of developed electromagnetic torque and rotor speed characteristics. Obtained result showed similar characteristics. Thus, we can conclude that our developed model in MATLAB/SIMULINK software is reliable, comparatively cheap, user-friendly and safer to study the performance and to predict the behaviour of 3-Φ squirrel cage induction motor. Our developed model can be used to study the performance of both the squirrel cage and slip ring induction motor.
