Laboratory Manual: You need to purchase 330:038 Lab Manual from UNI Print Services (147 Rod Library: 273-7722) after September 9, 2002. Prerequisites: 330:037 AC/DC Theory (Introduction to Circuits).

Course Catalog Description: Single and polyphase circuits. DC machines, AC single and polyphase synchronous and induction machines, power transformers. Introduction to power systems with renewable energy sources. Lecture and lab.

Course Objective:

To apply the theory of electrical machines “motors-generators-transformers” to the practical

industrial settings with appropriate drives and controls.

To learn the theory of major stationary and rotating electrical machines operating on DC/AC and

their corresponding control systems.

To establish the concepts of electrical power production, transmission, application, and the control

relating to the industrial and commercial setting.

To learn fundamentals of the National Electric Code (NEC) requirements and Electrical Safety

Rules for electrical systems.

Computer Use: An interface motor control interface software package (Feedback 68-910) available in motor control set-up in ITC 10 will also be used in laboratory projects.

Class Structure and Attendance: This is an important class and your attendance is highly encouraged. Lectures, laboratory experimental projects, homework assignments, pop-quizzes, and a design project with a final report will constitute the structure of the course. A make-up exam may be given only in the case of documented physical illness (In this case, students must inform instructor at least 24 hours before the exam).

Labs: There are regular scheduled labs for this course. You will buying your copy of the lab manual from UNI Print Services in the second week of September. All laboratory project assignments must be completed for your lab grading. Each student must write his/her own laboratory report. You must attend and successfully complete the each lab. Lab reports will be due one week after the week of the lab completed. Due to the limited number of lab setups, no make-up labs will be given. Please see the lab report format sheet for a sample lab report.

Homework Assignments: Homework assignments will be collected and graded. No credit will be given for late homework assignments (except documented physical illness). Students may work with others on lab reports and homework assignments, however, submissions must consist of the students own work, in accordance with departmental policies. Please work neatly, showing all calculations, manipulations, plots and program files (if any) required reaching your solution.

Course Content: The tentative course content will include the following topics. Please note that depending upon extra handouts, and homework assignment explanations, the following tentative course content and its corresponding laboratory projects may be shifted slightly.

1. Fundamentals Systems of Units, Per-Unit System, Magnetism, AC Circuits, Phasors, Energy,

Harmonics, Mechanics.

2. Electrical Machines and Transformers DC Generators DC Motors Efficiency and Heating of Electrical Machines Active, Reactive, and Apparent Power 3 Circuits Ideal and Practical Transformers Special Transformers 3 Transformers 3 Induction Motors Selection and Application of 3 Induction Motors Equivalent Circuit of the Induction Motor Synchronous Generators Synchronous Motors 1 Motors and Stepper Motors

3. Electrical and Electronic Drives Basics of Industrial Motor Control Introduction to Power Electronics Optional: (Power Electronics Control of DC Motors)

4. Renewable “Wind/Solar” Power Generation and Instrumentation.

5. NEC and the articles pertaining to electric motors/control, installation, residential wiring, transmission/distribution, SAFETY.

Design Project: All students are expected to complete an electrical power based project of interest. The project may involve construction of an electrical system, design of an electrical machine control system, design (and if possible implementation) of a solar/wind power system and instrumentation. It is recommended that projects not necessarily be very large or very complex. The student should make a decision early in the semester and arrange to discuss the project with the instructor. Each project will be presented to the class with a report. This will include the following:

(1) A brief description and purpose of the project(2) Plans, illustrations, schematic drawings, simulations, or other visual representations.(3) A written summary of the activities performed to complete the project(4) A discussion of fundamental principles needed to accomplish the project, (5) Measurement (if used) Results and Conclusions

and finally if possible (for extra credit)

(6) The actual physical project implemented for a demonstration in the class.

You should submit a proposal of the project by Monday, October 28, 2002. All projects must be approved by Wednesday, October 30, 2002. Students will be expected to present and submit their final project reports in the class on the final week of the semester (Monday, December 9, 2002). The literature review regarding the project should be documented, cited and supporting material should also be included on the final report.

Grading: The final grade is based on the following requirements.
