Interactive Learning of Electrical Machines Using ELMA Tool

In this paper, an interactive teaching and learning tool namely as ELMA has been successfully developed. ELMA stands for Electrical Machines where this tool is suitable for use in learning Electrical Machines subject or equivalent for engineering undergraduate students. ELMA covers the following four main topics: Transformer, Induction Motor, Synchronous Machines, and DC Machines. It is designed and inspired based on problems faced by previous students undertaken this subject. Its interactive feature allows the user to immediately observe the effect of changing parameter on the system behavior thus can help them better understand the subject. Apart from that, ELMA is also best to use during revision to validate the manual calculation which can accelerate the learning process. Not only that, this tool also can be used in classroom teaching to facilitate the understanding of the system behavior with the aid of provided corresponding illustration and waveforms. A survey has been conducted among the undergraduate electrical engineering students and the good feedback received indicates that ELMA has a potential to improve learning performance in Electrical Machines subject. The analysis of the survey is itemized in this work.
