Emetor - An educational web-based design tool for permanent-magnet synchronous machines

An educational web-based design tool for permanent-magnet synchronous machines (PMSM) is presented in this article. This tool, named Emetor, has been developed to be used in an undergraduate course on permanent-magnet machines. The technical aspects behind the tool, such as the PMSM's design procedure and the program architecture are presented. The benefits of Emetor in an educational environment are described. Different learning activities are presented to illustrate the potential of Emetor, as well as its suitability for education.
