403. Energy Conversion.  Introduction to electrical machinery.  Magnetic circuits.  Single and three phase transformers.  Autotransformers.  Synchronous machines.  Three phase induction motors.  Direct current machinery.  Three lectures.  (Cr.3) 

Corequisite: ELEC 401.

Course Goals: 

To introduce seniors in EE  to the concepts of flux,  magnetic fields and energy conversion,  to introduce design, testing and operation of transformers, Synchronous generators and motors, three-phase induction motor, and DC machines. 

Course Objectives: 

The student will be able to: 

·         Understand the concept of energy conversion via magnetic field

·         Understand design, operation and application of single- and three-phase transforms

·         Understand the basics of the operation of synchronous, induction, DC and Brush-less DC machines

·         Acquire as preliminary knowledge of testing and parameter identification for machines

·         Perform analysis of performance of these machines using simple models

3.          Magnetic Circuits 

               Topics: 

1.         Review of circuits and 3-phase systems     (1 classes)

2.         Electric field, flux, magnetic circuits, energy conversion (5 classes)

3.         Single and three-phase Transformers        (8 classes)

4.         AC machinery fundamentals, design and construction (7 classes)

5.         Synchronous generators     (6 classes)

Computer Usage: 

A transformer design project is assigned in which the students use a computer program to design a transformer according to specifications.  The students vary the design parameters to arrive at an optimum design while satisfying the specifications.

An animated computer graphic software package developed at Manhattan College is used in the classroom to show the rotor and stator current patterns and the interaction of magnetic fields inside the machine.
