This article describes the use of software tools and didactic equipment of electrical machines applied to the teaching in electrical engineering, specifically in the realization of an application work consisting of the characterization of the three‐phase induction motor. Several studies have explored the effectiveness of teaching activities, which encompass different learning tools in the same work, from the use of didactic materials to the use of professional computer tools. The objective is the simultaneous use of didactic equipment and the calculation methodologies through specific software of industrial applications in engineering studies. In addition, to observe whether performing application work that implementing different techniques at the same time fosters the critical spirit among students. The activities students must do in the application work proposed in the subject of rotating electrical machines is to determine all the constructive variables of an induction motor, draw it, simulate its electromagnetic behavior by finite element method with a freeware available 2D program, test the motor in the laboratory following the guidelines of the current standards and, finally, compare the results obtained from the tests and the simulation, by making a critique of the results and the calculation methodology used. The application work presented in the article has been implemented during several courses in the subject of electrical machines for electrical engineering students, with satisfactory results.

“…The usage of torque equation in machine design and analysis could be a fundamental requirement no matter in the studying period or in the later professional career. Efforts made so far, which try to give better understanding of machine principles and characteristics, are often based on computer-aided simulation and mainly focus on how machine parameters influence the machine performances [1], [2]; or experimental devices to illustrate the basic principles [3], [4]. However, there is only limited number of papers that try to provide a physical understanding of machine physics and therefore the equations [5], [6].…”

Electromagnetic torque analysis is one of the key issues in the analysis of electric machines. It plays an important role in machine design and control. The common method described in most of the textbooks is to calculate the torque in the machine variables and then transform them to the dq-frame, through complicated mathematical manipulations. This is a more mathematical approach rather than explaining the physics behind torque production, which even brings a lot of difficulties to specialist. This paper introduces a general and intuitive approach to obtain the dq-frame torque equation of various AC machines. In this method, torque equation can be obtained based on the intuitive physical understanding of the mechanism behind torque production. It is then approved to be applicable for general case, including rotor saliency and various types of magnetomotive force sources. As an application example, torque equations of permanent magnet machine, synchronous reluctance machine and induction machine are obtained, where torque production capability of each machine may be easily understood and a fair comparison of these machine types may then be carried out.

“…By using a new methodological approach [2] to teaching power electronics converter experiments, instructors have seen a noticeable increase in student interest in the subject. Similarly, the concept of "Self-Learning" [3] motivates students to attend Manuscript [4], and reducing practical hazards [5] are other fundamental issues in such laboratory experiments.…”

A general purpose experimental set-up has been designed and implemented for students to carry out various experiments on inverters in the power electronics laboratories of universities, during a few hours of laboratory work. This is the first inverter setup that incorporates hardware and software control, as well as an optional user interface in a laboratory experimental set-up of a single multi-purpose inverter, thus making the system versatile and very practical for both undergraduate and graduate students. The system can be controlled either by a computer or through a liquid crystal display (LCD) and a keypad control unit, and it constitutes a low-cost alternative to relatively expensive commercial teaching sets. The computer provides a user friendly interface and easier control for laboratory environments equipped with computers. The LCD and keypad units eliminate the need for a computer, which makes this system usable in the laboratory as a standalone unit as well.
