Modeling and Simulation of a Magnetic Levitation Virtual Module for Undergraduate Rotodynamic Teaching

In this research, a programming of a graphical user interface (GUI) was developed in the MATLAB environment to be used as a virtual teaching technological tool to design a rotor test bench with magnetic bearings. The programming of this virtual tool was based on the parametric design grounded on mathematical models of electromagnetism and resistance of materials, so that step by step, the user recognizes the influence of the information as it is added and determines through comparative curves the most appropriate data, improving learning in the subject through the analysis of results. This module allows to manipulate the input variables and geometric variables to calculate the data of the current in pole, load exerted by the pole, current flow; sizing of the elements of the test bench, in addition to calculating the electromagnetic forces necessary to levitate the axis of the steering wheel. Finally, the sizing of the shaft and active magnetic bearing are selected based on the available values provided by the manufacturer.
