Learning Outcomes

The unit aims to assign responsibilities for the creation and use of models in the study of electromagnetic systems conversion and electromechanical power systems transient and permanent. Assign also skills for analysis, selection and use of Direct Current Electrical Machines and Transformers.

Specific Objectives (Skills):
OB1: To know the fundamental principles of the electromechanical conversion of energy;
OB2: To know the principle of operation of the Electric Machine of Continuous Current, both in its operation as generator and in its operation as an engine. Know the main differences between the various types of machines and know how to use any of them;
OB3: To understand the phenomena related to the reaction of the armature and the commutation in the operation of the machines of direct current;
OB4: To know the principle of operation of the Single Phase and Three Phase Transformer, its constitution, selection and its calculation;
OB5: Know how to model the transformer through the exact and simplified circuit. By the analysis of the circuit, know the performance of the transformer in any regime of load or use.
