Course Objectives To provide an undergraduate level of knowledge on synchronous and DC machines used for generation of electric energy and driving industrial loads by means of basic magnetic field theory and energy conversion principles.
Course Description Construction of synchronous machines, excitation fields and their Fourier analysis, two-axis theory of salient-pole machines, reactances, armature reaction in synchronous generators and motors, equivalent circuits, characteristics at no-load and full load condition, phasor diagrams, short-circuit ratio, short-circuit current, synchronization, starting of synchronous motors, active and reactive power regulation, excitation methods, torque equations. Armature reaction, commutation, generator and motor characteristics, speed control and starting methods of DC machines.
Course Outcomes Students will have an understanding of the operating principles and characteristics of the synchronous and direct current machines.
Pre-requisite(s) There is no pre-requisite(s) for this course, however, your success in this course heavily depends on the good knowledge of the following topics:

1. Phasor analysis of AC circuits, computing RMS and average values, power factor, meaning of leading and lagging power factors.
2. Apparent, real, and reactive powers in single- and three-phase power system.
3. Algebra with complex numbers, transformation from rectangular to polar coordinate and vice-versa.

The above subjects will not be covered/explained in the class - this course assumes you have sufficient knowledge of these topics. If you feel that your background on the above material is insufficient, you are advised to take a look at your circuit's and mathematic's notes and/or books.
