Computer-Aided Teaching Using MATLAB/Simulink for Enhancing an IM Course With Laboratory Tests

This paper describes an automatic procedure using MATLAB software to plot the circle diagram for two induction motors (IMs), with wound and squirrel-cage rotors, from no-load and blocked-rotor tests. The advantage of this approach is that it avoids the need for a direct load test in predetermining the IM characteristics under reduced power. Additionally, to verify the validity of the equivalent circuit parameters deduced from experimental tests, these characteristics are used to simulate virtual machines implemented under Simulink/PSB models. Furthermore, a virtual load test is performed to validate the proposed model. Finally, the results are given of an assessment that reflects the positive impact the proposed methods have had on students´ learning experience in electrical machinery courses in the Electrotechnics Department, Engineer Sciences Faculty, University Mentouri of Constantine (ED-ESF-UMC), Algeria.
