Objectives
In the end of this course, students should be able to:
- Identify the main components of electromechanical drives, namely the power electronic converter, the electric machine, the command/control system and typical sensors.
- Apply fundamental concepts of electromagnetism and electromechanical energy conversion to the analysis of classic and special electric machines.
- Know distinct variables speed control techniques, with specific application to DC, synchronous and asynchronous motors.
- Understand and analyse transient regimes in electric machines, and its consequences in the operation of these devices.
- Understand and analyse special asynchronous machines, namely single-phase, linear three-phase, and polyphase with variable poles, and their equivalent models.
- Understand superconducting materials, namely high temperature, and its application in electric machines.
- Select motors and remaining drives components.
Prerequisites
- Fundamental notions of electromagnetism.
- Electromechanical energy conversion and theoretical electrotechnics.
- Control theory.
- Use of Matlab/Simulink tool.
- Previous attendance of Power Electronics in Drives course.

Evaluation method
Assessment comprises three tests during semestre, T1 to T3.
Final grade, Nf, is built by the following weighted average of grades in individual tests:
Nf = 40%.T1 + 40%.T2 + 20%.T3
T3 minimum grade is 8/20.
There is a final exam as an alternative to periodic assessments.
Frequency at the discipline implies attending demonstration classes and lecture(s) from industry(es) representative(s).
