Electric Machines Applications

Teaching Methodologies

In the theoretical component/lessons of this course, the theory associated with each subject is presented, being
complemented by solving exercises in which the acquired theoretical knowledge has to be applied. In laboratorial
component, one per-group research work in a selected topic, involving simulations and experiments, is carried out
in group, being mandatory the delivery of a report and oral presentation and discussion of its content. The final
exam includes theoretical and practical parts. The final grade is the weighted average of the exam and laboratory
grades, which have a 60% and 40% weight, respectively. In the evaluation of the laboratorial component, the report
quality and respective oral discussion are taken into account. The laboratorial classes are mandatory, being
required a minimum assiduity of 80% of the total number of classes. The access to the exam is only possible if the
student has a minimum of 50% in the laboratorial component classification.

Learning Results

With this curricular unit, the students should acquire theoretical, practical and laboratorial knowledge on the most
common industrial electromechanical motor systems. In the end of this course, the students should be able to
design, analyze, optimize, protect and maintain electromechanical motor systems, integrating three-phase
induction motors, soft-starters, variable-speed drives, contactors, protections and/or mechanical transmission.
From a general perspective, the students should acquire the ability to perform scientific decisions and judgments
associated with the acquired theoretical and practical knowledge, and to promote ideas interchange and the
discussion of problems and solutions, develop a professional attitude in his relation to work and acquire
self-knowledge habits.
