EE 3033- Electric Machines


Fall 2009

Time: TT 11:00-12:15

Office Hours:


Office: U395






The aim of this course is to introduce magnetics to electrical systems and mechanical energy conversion. Key elements include machine models, two-port networks, and one-port equivalent circuits along with power flow diagrams. Discussion and models include single coil devices; rotating machines - induction, synchronous, and direct current; fixed machine - transformer; controls; protection and transmission lines. The common element of all machines is a magnetic coil.

The application component includes public safety, Codes, and professional ethics. Professional interaction and activities are a valued component.

The class will include both lecture and hands-on components in the form of multiple projects.

Letter grades:

Division points between letter grades will be based on student performance and best judgment of the instructor.




As an integration of technical principles and practices, amateur radio includes every facet of electrical engineering from digital and power to controls, signal processing, and wireless rf signals. It is the ultimate application of electro-magnetics. It provides a spectrum to experiment with any medium. For this component, pass the next level license. In addition, attend a club meeting and make a one paragraph memo about the time, location, speaker and topics discussed. Complete a project option of your choice and prepare a memo. The supplemental text is Technician Class Amateur Radio, Element 2, by Gordon West, Master Publishing.


Professional development is a continuing requirement of engineers. IEEE is the largest engineering professional society on the planet. For this component, attend a student or section meeting and make a one paragraph report about the time, location, speaker and topics discussed.

Energy  Paper:

Write a 1-2 page technical paper about any energy source and supply that is ultimately converted to electrical. It should include the fuel source, energy density, cost/kw, cost/kwh, infrastructure cost, who pays for infrastructure, and life cycle cost.
  Ethics  Paper: Write a 1-2 page paper about professional ethics and the responsibility of the engineer to the public, employer, client, and himself. Discussion of various Codes of ethics or a case study is acceptable.

Remember when you obtain information from any source including the web, you must give credit to the source. To not do so is plagiarism, grounds for dismissal, and a real ethical problem. Check around, you will find the professor does enforce this.

1. You are a responsible adult.  I assume everyone wants to excel and enjoy the venture. If you want to learn, you will have to invest time and effort outside of class. If you want to slide that is your prerogative and your loss, and complaints about the course will go to the appropriate place. Continuous improvement is a part of the process. Let's have fun and learn.


2. People learn and absorb information in different ways. What is enjoyable or traditional to you may be frustrating to others. A variety of processes will be used to present the material. If a particularly style or technique does not fit you, accept it for what it is. Regardless, you can gather valuable insight in how others see things.


3. In this class, grasping concepts and relationships is more important than memorizing how to do formulas. As a result, there will be more discussion and less problem solving in class. You will be expected to practice solving the problems based on the discussion. In practice, your boss will not solve the problems for you but will give you the parameters. The University engineering education is about teaching you how to think.


4. Prepared notes will be provided as the basis of many discussions. Please do not be lulled. Most people can only improve learning by making notes in your own words and style. The book will be a supplement for further discussion, examples, and problems.



1. Attendance in class is expected. Points will be taken off final grade for poor attendance, particularly in the form of class participation and evaluation of and by colleagues.

2. There is no such thing as a stupid question, except the one not asked. Chances are others don't understand it either.

3. Students are expected to seek assistance if necessary. The instructor interprets students coming to his office to ask questions as eager beavers worthy of high grades. Students in trouble who don't try to straighten out their problems immediately and then say simply, "I never understood that" are in more trouble than they think.

4. No make up exams or late assignments will be permitted unless arranged in advance.

5. Fallibility of instructors is uncommon. However, in the unlikely event of a difference in opinion on grading, the question must be resolved within three days. Senility is common. Therefore, grades are as-is where-is for time greater than three days after posting.

Your job: 

The professor recognizes that problems of learning, earning, yearning, spurning, squirming and slumbering are unique to student life. Such problems will be treated with civility by a southern gentleman, but not with a great deal of compassion. You are a unique individual, wonderfully made, but the University environment demands your working within the same constraints imposed on others.


  Acknowledgment:  Like all software packages, your acknowledgement is solicited.
