ELEX 7240 - Electric Machines

Electrical and Computer Engineering Part-time Studies Course

School of Energy

Course Details

This is a rigorous introductory course in electromechanical energy conversion devices. Primary emphasis is placed on rotating AC and DC machines. Following a brief review of electromagnetic field theory and polyphase AC circuits, magnetic materials and circuits are introduced, using transformers as representative systems. A systematic approach to modeling machines is introduced, based on the principle of virtual work. This framework, applicable to general dynamic conditions, is applied narrowly to the steady-state operation of AC synchronous and asynchronous machines, as well as DC machines. Equivalent steady-state circuits are developed for common rotating machines. Practical information relating to general machine characteristics and nominal ratings is provided. Laboratory experiments are conducted to reinforce theory and to provide practical experience with motors and generators.
