Objectives
Provide the capabilities for chosing and operating of systems with actuators.

Program
1. Electrical machines: operating principles of electrical machines; the transformer; the synchronous machine; the asynchronous machine; DC motors (motor / generator: series, parallel, compound and of permanent magnet); other types of rotary machines (motors, brushless, coreless and step). Operation, constitution, characteristics, testing, start-up and reversal of the direction of operation.
2. Adaptation system of mechanical parameters: gearboxes, rotational motion to linear conversion, efficiency, needs in terms of operating quadrants of the mechanical variable for each application.
3. Non electromagnetic mechanical Actuators: piezoelectric, pneumatic, hydraulic, etc.
4. Non mechanical Actuators: light, acustic, electrical, thermal, etc.
5. Introduction to the power electronics and its use for the control of various types of actuators. Components: diodes, transistors, IGBTs, thyristors. linear operating systems and PWM types of commutated converters and their operating principle: AC-DC, DC-DC, DC-AC.

Evaluation Methodology
Written test: 60%. Laboratory practice: 40%. No minimum rating.
