【Power Electronics】【2018.08】Equivalent circuit of three-phase asynchronous motor

This article is Czech Technological University: Master's thesis (Author RISHABH TATHGIR), a total of 55.

For the purpose of automobile propulsion, this article models, simulates and verifies the three-phase asynchronous motor using direct torque control and inverter. The purpose of this paper is to simulate an induction motor given a set of inputs as load torque and motor speed, and the output is motor torque, speed, power, three-phase current, AC voltage, power factor, DC current and Voltage and compare these outputs with actual test results from Roztoky’s Choft laboratory. The model established by MATLAB/Simulink can be used to observe the performance of any motor under different working conditions.

Therefore, the operation of the direct torque control induction motor is basically simulated. It replaces the method of actually testing one motor at a time, and simply uses the model to obtain performance outputs and parameters under different motor specifications.

The paper is about Modelling, Simulation and Verification (by way of practical testing) of 3-phase Induction Motor with Direct Torque Control and Inverter, for the purpose of vehicle propulsion. The purpose of my thesis is to simulate the outputs, for a given set of inputs being load torque and motor speed, of an Induction Motor performance, and outputs being motor torque, speed, power, 3 phase currents, AC voltage, power factor and DC current and voltage, and then compare those outputs to that obtained from practical testing of the motor in ČVUT Laboratory in Roztoky. This model, made using MATLAB/ Simulink, can then be used to see the performance of any motor at varying conditions, thus, basically simulating the working of an Induction Motor with Direct Torque Control. It is to replace practically testing a motor at every time and simply use the model to get the performance outputs and parameters, for different motor specifications.
