Prerequisites
Not applicable.

Objectives
The students will familiarize themselves with the safe operation of asynchronous machines (both rotating and linear), asynchronous machines and some special engines under safe conditions for equipment and user.

Program

Starting and speed control methods of these 3-phase machines. 3-phase linear motors. Fundamentals and field systems of synchronous machines. Testing methods, curves and voltage regulation. Alternators and synchronous motors in the grid. Special motors.

Evaluation Methodology
Final mark=3/4 of the points of a written exam + 1/3 of the average mark of laboratory work
