This project involves modelling and simulating a real three-phase induction motor to determine its transient and steady-state characteristics, such as its torque-speed characteristics, torque-time characteristics, speed-time characteristics and its rotor and stator currents. For the simulation the computer program MATLAB/Simulink was used. The motors equivalent circuit parameters were determined by performing the standard equivalent circuit parameter tests; the DC test, no-load test and the blocked-rotor test. The moment of inertia of the motor was attempted to be determined through power and deceleration tests, although the method proposed in this paper proved to be unsuccessful. The resulting equivalent circuit parameters determined from the suggested tests were highly unlikely for the 0.37 kW motor used, however the MATLAB/Simulink computer program proved to be a suitable program to simulate three-phase induction motors.
