Fundamentals of Electrical Machines

• 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

  Teaching is based on theoretical and practical classes. The students are motivated to assume an active attitude in the research of basic information, in the resolution of application problems and in the planning of the group works that will be assigned to them. The approval presupposes that the student succeeds: - in the 1st test (20%) and in the 2nd test (50%), in order to evaluate that the students have acquired the necessary knowledge about the programmatic contents; - group work (2 or 3 students per group) that reflects the knowledge acquired by the students, at the end each group will present their work to the other groups (50%). All students must participate in the evaluation activities, the attendance/commitment is valued at 10%, for students with at least 70% attendance. At the end of the semester, students may take an appeal exam (upon registration) which allows the student to replace one of the previous exams with a classification lower than 10 marks.
