Course Goals 
This is one of the technical electives (3 out of 5) in the EE curriculum. The goals are to impart basics of three phase power circuits, transformers and electromechanical systems with an emphasis on rotating machines. This addresses the ECE department Program Educational Objectives to provide depth, breadth, and learning environment.
The letters (a)(n) refer to ABET Criterion 3 as follows: (a) Ability to apply knowledge of mathematics, science, and engineering (b) Ability to design and conduct experiments as well as to analyze and interpret data (c) Ability to design a system to meet desired needs within realistic constraints such as economic, environmental, social, political, ethical, health and safety, manufacturability, and sustainability (d) Ability to function on multidisciplinary teams (e) Ability to identify, formulate, and solve engineering problems (f) Understanding of professional and ethical responsibility (g) Ability to communicate effectively (h) Broad education necessary to understand impact of engineering solutions in a global, economic, environmental, and societal context (i) Recognition of the need for and ability to engage in lifelong learning (j) Knowledge of contemporary issues (k) Ability to use the techniques, skills, and modern engineering tools necessary for engineering practice (l) Knowledge of probability and statistics, including applications to electrical/computer engineering (m) Knowledge of mathematics, and basic and engineering sciences, necessary to carry out analysis and design appropriate to electrical/computer engineering (n) Knowledge of advanced mathematics A. At the end of three weeks of classes the students should be able to analyze single and three phase sinusoidal balanced circuits (a, k). This includes being knowledgeable in the following topics:
B. At the end of six weeks of classes, the students should be able to analyze magnetic circuits (a, c, e, k, m, n). This includes being knowledgeable in the following topics:
