Fundamentals of Electrical Machines

Electrical Installations and Automation
  • ApresentaçãoPresentation
    The curricular unit of Electrical Machines intends to provide the students with a set of basic knowledge that allows them to understand the phenomenon of electromechanical energy conversion and the basic operation of the electrical machines most used in industry.
  • ProgramaProgramme
    CP1. Single-phase transformer - construction aspects; - working principle; - operation: - no-load - on load; - losses and efficiency.   CP2. Three-phase asynchronous motor - construction aspects; - working principle; - rotating field; - speed and torque; - starting and braking systems; - speed regulation.   CP3. DC motor - with parallel excitation; - compound excitation; - construction aspects; - operating principle and characteristics; - starting and speed regulation.   CP4. Synchronous Motor - constructive aspects; - synchronism; - working principle; - special electric motors: - stepper motor; - reluctance motor.   CP5. Introduction to Power Electronic Converters
  • ObjectivosObjectives
    Know the electrical machines from the user's point of view and analyse their behaviour and applications based on their equivalent circuits. The students should acquire basic skills that will enable them to: OA1. to identify the importance of electrical machines; OA2. to recognise, distinguish and compare the different types of electrical machines; OA3. to understand the operation mode, equivalent circuit and construction characteristics of electrical machines; OA4. to use equivalent circuits of electrical machines to analyse their behaviour under various operating conditions under permanent regime; OA5. introduction to power Electronic converters.

  • MetodologiaMethodology
    The classes are dedicated to the discussion and exposition of the curricular contents and are oriented to the analysis and resolution of practical problems, allowing students to acquire knowledge about the electromechanical energy conversion and the basic operation of electrical machines, which will enable them to select and use electrical machines in several industrial applications. The classification of each continuous assessment activity takes into account the individual performance of the student(s), also taking into account their communication skills, either orally, by answering questions that are asked during the face-to-face session, or in writing, through the work that is requested.
