Topic | Sub-topic |
Topic Sub-topic Section I: ELECTRIC MOTOR PERFORMANCE | Topic 1: INTRODUCTION TO ELECTRIC DRIVES. It gives an overview of electric drives and the types of loads. It also discusses the mechanical aspects (static and dynamic) of the load-motor coupling. Topic 2: D.C. ELECTRIC DRIVES: PERFORMANCE, STARTING, BRAKING, AND SPEED REGULATION. It covers the possibilities and strategies for regulating direct current machines, with a focus on separately excited and series type motors. Topic 3: A.C. ELECTRIC DRIVES: PERFORMANCE, STARTING, BRAKING, AND SPEED REGULATION. It addresses the possibilities and strategies for regulating alternating current machines, mainly asynchronous machines and synchronous machines as well. |
Block II: Dynamic Models of Electric Machines | Topic 1: DYNAMIC MODELS OF ELECTRIC MACHINES. An approach to the dynamic modeling of electric machines is provided, including electrical and mechanical aspects. |
Block III: Systems and control algorithms in electrical machines. | Topic 1: DYNAMIC MODELS OF ELECTRIC MACHINES. An approach to the dynamic modeling of electric machines is offered, including electrical and mechanical aspects. Block III: CONTROL SYSTEMS AND ALGORITHMS IN ELECTRIC MACHINES Topic 1: METHODS AND ALGORITHMS FOR ELECTRIC MACHINE CONTROL. The physical part of an electric machine control system, control algorithms, and their implementation in a digital signal processor are described. Topic 2: VARIABLE FREQUENCY DRIVES. For each type of machine seen in Block I, the control system and the most suitable power stage are proposed depending on the type of load to be driven and the system dynamics. Practical examples of each type of variable speed drives are also reviewed. |

Methodologies |
Description | |
Laboratory practicals | Small groups will be created with a very small number of students to work on a practical assignment assigned to each group, consisting of carrying out the practices indicated, as well as preparing the corresponding practice report. Students will have the necessary documentation and materials available to carry out the practices. In this way, with the clarifications provided in due time by the teacher, the student will be able to carry out the practical assignment. Students will take note of the results and prepare a report that must contain the theoretical foundations, the practical implementation, the results obtained, and the specific conclusions of their work. The student will submit a single project-work-summary as the evaluation criteria for the practical part, under the conditions and dates indicated later on. A grade of 5.0 out of 10.0 is required to pass the practical assignment. |
Problem solving, classroom exercises | Formulation, analysis, resolution, and discussion of a problem or exercise related to the subject matter of the course. The goal is for the student to be able to understand the theoretical content presented in the lectures. |
Personal tuition | It will be dedicated to solving specific doubts about issues that students may have. |
Lecture | First, a theoretical explanation of all the concepts included in the program is presented. Then, the concepts are justified and their application to specific cases is shown. |
Personalized attention |

Assessment |
Description | Qualification | ||
Lecture | The student's participation in class and in the debates that take place in the classroom will be evaluated. Regular attendance and the attitude shown may be taken into account for the evaluation. | 2.5% | |
Laboratory practicals | Evaluation of internship assignments. The skills acquired by the student in the practical application of knowledge will be valued. All scheduled practices must be completed and all required work and reports must be submitted in order to pass the subject. Attendance at practice sessions is mandatory to pass the subject. The evaluation of the practices will be done once the minimum set in the tests and exams of the subject has been passed. Submission is mandatory and a grade of 5.0 out of 10.0 in the test is required. No average will be calculated if this condition is not met. The total weight of the practical part will be 20%. No assignment or test will have a recovery option. The internship report will be submitted in PDF format through Moodle (adhering to the maximum size allowed by the platform). Deadlines for submission will be set throughout the course. |
20% |
|
Mixed tests | They will be designed to assess the competencies acquired by the student. The grade for this part will be the weighted average (based on the credits assigned to each part) of two partial exams that will be carried out throughout the course. Grades below 5.00 in one of the partial exams will not allow for an average to be calculated, and the grade of that partial exam will be transferred as the final grade for the subject. Regular attendance to classes and the attitude shown may be taken into account for the evaluation. To pass the subject, it will be necessary to pass the mixed tests and the laboratory practices. |
75% | |
Others | Resolution and delivery of problems proposed by the teacher. | ||
Other comments and second call | |||
All documents must be submitted either through the Moodle platform (PDF format only) or in paper format, or both. Email submissions are not allowed, and late submissions will not be accepted. The file name should consist of the student's National ID (NIF) followed by their first name and last name, along with an identification of the problem or test. Each document must include the student's name, NIF, and the solution to the problem or assignment, including: Introduction or statement Objectives Solution or practical execution Analysis of the solution Conclusions and personal assessment Attendance at Individual Character Tests and Reviews: Students must bring valid identification. Tests will cover material equal to or more advanced than that covered in class to allow high-achieving students to earn outstanding grades. Exams may be video-recorded for fraud detection purposes. Any proven cases of cheating will result in a suspension of two exam opportunities or disciplinary action as per university regulations. Students must adhere to examination regulations set by the University of León. Test Materials and Conduct: Students are allowed to bring specific materials to the exam room, including pens, a correction fluid, a ruler, a non-programmable calculator, and additional materials if permitted. Only clear water in a transparent bottle is permitted, with strict usage guidelines. Electronic devices such as phones or tablets are strictly prohibited. Communication or sharing of materials with other students during the exam is forbidden. Only blue or black pens are allowed for writing; red ink is prohibited. Leaving the exam room while another student is still working on the test is not allowed. No food or drinks except water are allowed in the exam room. Grading and Evaluation: Each test or assignment must be passed with a minimum score of 5.0 out of 10.0. No averaging with other parts of the evaluation is done if this condition is not met. There are no retakes for any test or assignment. Regular attendance and attitude may be considered in the evaluation process. Students must pass each content block to pass the course. If one or more blocks are not passed, the average score of those blocks will be the final grade. Second Call: Theory evaluation consists of one or more written tests covering program content and contributes 80% to the total course grade. Practical evaluation involves retaining the grade obtained in laboratory practices. Alternatively, if the student prefers or has failed the practicals, they must pass an alternative exam. This alternative exam contributes 20% to the total course grade. These guidelines provide a comprehensive framework for assessment, evaluation, and conduct during exams and assignments. |
