Dynamics of Electrical Machines

The course Dynamics of Electrical Machines is aimed to provide advanced knowledge on electrical machines as required in modern applications and useful for the machine control. The study of the electrical machines will begin stating the operating principles of the rotating AC machines and their equivalent circuits, therefore, it will continue with the study of the dynamic operation and models. The equivalent circuit at qd0 will be introduced according to the generalized theory of electrical machines (or of the arbitrary references frames).

Objectives
After completing the course the student will acquire the enabling knowledge for using the electric machines in static and dynamic loads in all industrial and civil applications with particular attention to energy saving, for example electrical traction, energy production and conversion, renewable energy.

Assessment methods, criteria and period

The exam consists of an oral test. The oral exam typically consists of 3 main questions which are followed by an in-depth discussion on the subject. The final evaluation will take into account the acquired knowledge, skills, clarity of presentation and the property of technical language. The average duration of the oral exam is 90 min.

The knowledge of circuit theory.  The students have completed a basic course on Electric Machines considering steady-state operation.
