图书简介
This is a revision of Guru/Hiziroglu: Electric Machinery and Transformers 2/e. The text is designed for the standard third or fourth year (junior/senior) course in electrical engineering commonly called electric machinery or electromechanical energy conversion. This text discusses the principles behind building the primary infrastructure for the generation of electricity (such as hydroelectric dams, turbines, etc.) that supplies the energy needs of people throughout the world. In addition to power generation, the book covers the basics of various types of electric motors, from large electric train motors, to those in hair dryers and smaller devices. The largest markets for a book such as this will be found in countries with developing infrastructures.
