Evaluation Methodology:
The teaching of the syllabus, in the theoretical component, is to present the concepts and definitions. The theoretical-practical component aims to stimulate the development of electrical machine systems and their applications in renewable energies. The evaluation is done with two frequencies, each with a weight of 25%. The practical component is evaluated with four practical assignments, each with a weight of 7.5%, and a project, with a weight of 20%.
