Objectives

This course aims to provide students with a basic set of knowledge in the field of electromechanical systems. In particular the goal of this course is to present and develop a set of concepts and knowledge in the field of electrical drives, mechanical transmission elements, and electromechanical switchgear components for protection and control, and supervision and control devices. 

Learning outcomes and competences

At the end of the course, the student should be able to:
-Identify the structure of an electromechanical drive system and its components.
- Describe the operational principle of electric motors: servo motors, induction motors, DC motors and stepper motors.
- Understand and perform a critical analysis of the technical data made available by manufacturers of electric motors.
- Analyse and specify electromechanical switchgear components for protection and control.
- Analyse and specify mechanical transmission elements suitable to be used in electromechanical drive systems.
- Describe the functional principle of the various types of sensors associated with the use electromechanical drive systems.
- Analyse and specify sensing elements to integrate in electromechanical drive systems.
- Describe the working principle and analyse the characteristics of frequency inverters.
- Analyse and specify solutions for electromechanical drive systems.
- Have the capability to model and simulate electromechanical drive systems.

Teaching methods and learning activities

This course is based on the following complementary activities that involve lecturing and learning:
1. Theoretical notions: the exposition of ideas and theoretical concepts is done during theoretical classes and should be learned by students through activities of study and conceptualization.
2. Theoretical and practical-cases: the exposure of case studies and respective solutions is done during the theoretical-practical classes. Students are required to study and explore those cases and solve new proposed problems autonomously. These classes are also used to present different equipment of electromechanical drive systems and to conduct demonstrations. Students have the opportunity to practice using the available equipment and implement control solutions.
