General description Nesta materia estúdanse os diferentes accionamientos das máquinas eléctricas, fundamentalmente as distintas tecnoloxías a empregar nas máquinas de corrente alterna, identificando as vantaxes segundo os procesos e analizando os sistemas de control necesarios, que se empregan nas enerxías renovables, fundamentalmente na eólica.
Diríxese tamén aos alumnos interesados na tecnoloxía dos vehículos eléctricos, tanto híbridos como eléctricos puros, unha alternativa real aos vehículos actuais.

Methodologies
Methodologies Description
Guest lecture / keynote speech It is done in the classroom, the fundamentals of the subject are explained . Using multimedia means to facilitate learning.
Laboratory practice They consist of case studies where the student must demonstrate the acquired theoretical knowledge. You perform necessary to pass the subject .
Problem solving The teacher makes standard problems , proposing solutions and providing resources to students.
Objective test Evaluation test to be held at the end of the course, in the corresponding official announcements, where the student must demonstrate the degree of learning in an objective manner . They consist of a number between 15 and 20 multiple choice questions , accompanied by 6 possible answers , where only one is correct , students must always justify the answer , this being an indispensable condition for the answer to be accepted as correct.
