1. Introduction
   The three-phase induction motor is one of the most common motors in industry. Its simplicity, reliability and high efficiency make it widely used in various fields. In order to better understand and study the operation mechanism of the three-phase induction motor, it is very necessary to establish a reliable and accurate mathematical model.

2. Basic Principle
   The three-phase induction motor works on the principle of electromagnetic induction. Its basic structure includes a stator and a rotor. The stator winding generates a rotating magnetic field through a three-phase AC power supply, while the induced current in the rotor conductor generates torque to make the motor rotate.

3. Mathematical model
   In order to establish the mathematical model of the three-phase induction motor, it is necessary to consider the electromagnetic characteristics and dynamic response of the motor. Using the three-phase circuit theory and the equivalent circuit principle of the motor, the voltage equation, current equation and torque equation of the motor can be obtained.

4. MATLAB Simulink ModelingMATLAB
   Simulink is a powerful simulation software that can easily model and simulate circuits and systems. In this study, we used MATLAB Simulink R2015b version to build a simulation model of a three-phase induction motor.

4.1 System Construction
First, create a new model in MATLAB Simulink and add the required modules and components. We can use the electrical module in Simulink to simulate the voltage and current of the motor and the integrator module to simulate the speed of the motor.

4.2 Parameter Setting
Next, we need to set the parameters of the three-phase induction motor, including the stator winding current, rotor resistance and rotor inductance, etc. These parameters can be set according to the actual situation of the motor.

4.3 Simulation operation
After the model is built and the parameters are set, we can perform simulation operation. By adjusting the power supply voltage and speed command and other parameters, we can observe the dynamic response and performance characteristics of the motor.

5. Result Analysis
   Through the simulation results, we can get the performance parameters of the motor such as speed, torque and power. At the same time, we can also analyze the response characteristics of the motor under different working conditions through waveforms and curves.

6. Experimental Verification
   In addition to simulation analysis, we can further verify the accuracy and reliability of the model through experimental verification. By actually measuring the motor’s speed and torque and comparing them with the simulation results, the accuracy and reliability of the model can be evaluated.

7. Conclusion
   Based on MATLAB Simulink software, this paper successfully established a dynamic mathematical modeling simulation model to study the operating principle and performance characteristics of the three-phase induction motor. Through the construction and simulation analysis of the model, the dynamic response and operating characteristics of the motor can be better understood and analyzed. The experimental verification results show that the model has high accuracy and reliability.
