A virtual electric machine laboratory for synchronous machine application

Abstract.Within education, concepts such as distance learning, and open universities, are now becoming more widely used for teaching and learning. However, due to the nature of the subject domain, the teaching of Science, Technology, and Engineering are still relatively behind when using new technological approaches (particularly for online distance learning). The reason for this discrepancy lies in the fact that these fields often require laboratory exercises to provide effective skill acquisition and hands-on experience. Often it is difficult to make these laboratories accessible for online access. Either the real lab needs to be enabled for remote access or it needs to be replicated as a fully software-based virtual lab. We argue for the latter concept since it offers some advantages over remotely controlled real labs, which will be elaborated further in this paper.We are now seeing new emerging technologies that can overcome some of the potential difficulties in this area. These include: computer graphics, augmented reality, computational dynamics, and virtual worlds. This paper summarizes the state of the art in virtual laboratories and virtual worlds in the fields of science, technology, and engineering. The main research activity in these fields is discussed but special emphasis is put on the field of robotics due to the maturity of this area within the virtual-education community. This is not a coincidence; starting from its widely multidisciplinary character, robotics is a perfect example where all the other fields of engineering and physics can contribute. Thus, the use of virtual labs for other scientific and non-robotic engineering uses can be seen to share many of the same learning processes. This can include supporting the introduction of new concepts as part of learning about science and technology, and introducing more general engineering knowledge, through to supporting more constructive (and collaborative) education and training activities in a more complex engineering topic such as robotics. The objective of this paper is to outline this problem space in more detail and to create a valuable source of information that can help to define the starting position for future research.Key words: virtual laboratory, dynamics based virtual reality, virtual world, distance learning for engineering/STEM education, immersive education IntroductionRecently we have seen a number of new ideas appearing in the literature concerned with the future of education and in particular for the teaching of Science, Technology, and Engineering (STE 1 ). Some of these notions are novel while others are a re-imagining of existing ideas but in a new context. Technological examples most relevant for this study are: distance learning, elearning, virtual laboratories, virtual reality and virtual worlds, avatars, dynamics-based virtual systems, and the overall new concept of immersive education that integrates many of these ideas together. Many highly reputable institutions 2 have gathered around this challenging concept, withi...

This article presents the development of an education purpose toolbox for performance analysis of three-phase line start permanent magnet synchronous motors. The motor state-space equations are implemented in Simulink and an easy to use graphic user interface is designed. The starting performance of a typical motor is then simulated in different conditions as a case study. This toolbox provides a friendly and efficient environment for students to become familiar with the performance of this type of motor which is receiving increasing attention in the industry and academic. An experimental study is also carried out to validate the toolbox. ß

Since operation of virtual winder can relieve the problem of lack of experiment on real equipments, virtual winder can be valuable complements to physical winder operation experiment. Virtools is the most widely used software for creating 3D VR environment. In this article, using Virtools to construct a virtual winder is demonstrated in detail by dividing the whole process into five steps: (1) creates 3D winder models in 3ds Max; (2) exports the models to Virtools format using Expert plugins (3ds Max Exporter); (3) designs scenes including cameras and lighters; (4) constructs the virtual winder including Behavior Building Block (BB), Scripts, and Virtools Scripting Language (VSL); (5) synthesizes and exports interactive coursewares of the virtual winder. The considerations and discussions in this article may be useful for building system of virtual education equipment in other subject areas. ß
