Objectives
Objectives
The main objective of the Electrical Machines I subject is to teach the theoretical and practical foundations of electrical machines, covering both scientific and technological aspects. Specifically, students will be trained to: - Master the concepts relating to single-phase and three-phase transformers: - Identify the basic components and most relevant parameters to define the electrical characteristics of transformers. - Dimension these parameters and design the implementation of transformers to achieve desired electrical characteristics. - Master the concepts related to direct current machines (MCC): - Identify the types, basic components and most relevant parameters to define the electrical and mechanical characteristics of each MCC. - Select the appropriate type of MCC and size these parameters, designing its implementation according to the desired electrical characteristics.

Teaching methodologies and assessment
Teaching methodologies and assessment
The Electrical Machines I discipline uses a teaching methodology that integrates theoretical and practical approaches, focusing on innovative methods such as: - Project-Based Learning (PBL): Students participate in practical projects involving the sizing and implementation of transformers and DC motors. - Experimental Tests: Carrying out laboratory tests to validate theoretical concepts and develop practical skills. - Computer Simulations: Use of simulation software to model electrical machines, allowing a deeper understanding of the machines' behaviors and characteristics. - Group Work: Development of group projects, promoting collaboration and the ability to solve complex problems. - Laboratory classes: to improve the practical understanding of theoretical concepts, allowing students to apply the knowledge acquired in real situations and develop technical skills essential for their training.
