espanolEste articulo ilustra el alto potencial de Microsoft EXCEL para la implementacion de herramientas orientadas a la visualizacion de principios fundamentales en ingenieria electrica para una mejor comprension por parte de los alumnos. En particular, se ha considerado y puesto en practica el Teorema de Ferraris, en el cual se basa la operacion de las maquinas electricas rotativas. De esta forma, se puede representar graficamente de una forma sencilla el diagrama fasorial de una maquina giratoria, permitiendo a los alumnos visualizar como al modificar los diferentes parametros clave de la maquina (como la magnitud o el angulo de las corrientes que circulan por el devanado inductor) se ve afedtado el campo magnetico obtenido en el entrehierro. El articulo evidencia la adecuacion de Microsoft EXCEL para este tipo de aplicaciones, mostrando ventajas significativas para los estudiantes cuando se compara con otras herramientas comerciales. En consecuencia, el trabajo que aqui se presenta pone de manifiesto la manera en la que una hoja de calculo puede utilizarse para ayudar a los estudiantes a comprender mejor los fundamentos del electromagnetismo y la ingenieria electrica a traves de herramientas de visualizacion que pueden ser facilmente implementadas por los profesores o por los mismos estudiantes. EnglishThis paper illustrates the high potential of Microsoft EXCEL for the implementation of tools oriented to the visualization of fundamental principles in Electrical Engineering for a better students understanding. In particular, the application to the Ferraris’ Theorem, which bases the operation of rotating electric machines, is considered and put into practice. Thus, the graphical representation of the phasor diagram of a rotating machine, is obtained, which allows students to visualize how the modification of different key parameters such as the magnitude and angle of currents, affects the obtained magnetic field in the air gap. The paper evidences the suitability of Microsoft EXCEL for this kind of applications, which show significant advantages to students when compared to other commercial software. Consequently, the work here presented evidences how a spreadsheet may be used so as to help students to better understand the foundations of electromagnetism and electrical engineering by means of visualization tools which may be easily implemented by professors or even by the students themselves.

Herramientas de visualización en ingeniería eléctrica basadas en Microsoft EXCEL: aplicación práctica al Teorema de Ferraris

Herramientas de visualización en ingeniería eléctrica basadas en microsoft excel: aplicación práctica al teorema de ferraris

Recent development in classical electrodynamics has demonstratedthe usefulness of different rotational and topological modes in theelectromagnetic fields (angular momentum, polarization, vorticityetc.). Unfortunately, the visualization tools available to illustratethese electrodynamic quantities have hitherto been inadequate.Therefore we have developed a VTK and Python based interactivevisualization tool, with working name EMVT (ElectroMagnetic VisualizationTool), targeted at visualizing precisely these modes.In the near future, EMVT will be further developed to visualize andcontrol live antenna systems, where electromagnetic field data isinstantly received, calculated, and visualized from an antenna or asystem of antennas. It will then be possible to see how the antennaproperties change through direct user interaction in real time.
