Course description and aims
In this course, students will understand the basic principles of electric–mechanical energy conversion for all widely applied electric machinery and apparatus such as motors and generators.
The study of electric machinery and apparatus has been a significant electrical subject since the days of Edison and Tesla, and is still significant due to its close relationship with subjects of note in recent years such as the global warming issue and hybrid automobiles.
Student learning outcomes
By the end of this course, students will be able to understand the principles and basic structures of DC machines, AC machines, transformers, and reactors, and calculate the basic characteristics of actual instruments.
Keywords
DC machine, induction machine, synchronous machine, permanent magnet machine, motor, generator, transformer, reactor, electro-mechanical energy conversion
