Abstract

This paper presents an Excel-VBA implementation tool for teaching some fundamentals of rotating electrical machines in undergraduate and graduate level, particularly for electrical engineering curriculum. The basic concepts of a Direct Current (DC) motor operation and a DC generator have been simulated for several operational scenarios. The simulation results have been compared to mathematical models implemented in the Matlab/Simulink© environment using the 4th Runge-Kutta method for numerical solution of the differential equations that correspond to the dynamic behavior of the electrical machine. In addition, some experimental results have shown a good approximation between the simulation results obtained from the proposed virtual tool and the experimental data. Therefore, the present development is capable of serving as a potential virtual lab for a better understanding of rotating electrical machines concepts, particularly for undergraduate courses.
