Electrical Machines Fundamentals of Electromechanical Energy Conversion by Jacek F. Gieras | PDF Free Download.
The book is meant to function a textbook for basic courses on electrical machines covering the basics of the electromechanical energy conversion, transformers, classical electrical machines, i.e.,
DC brush machines, induction machines (IM), wound-field rotor synchronous machines and modern electrical machines, i.e., switched-reluctance machines (SRM) and static magnet (PM) brushless machines.
The author breaks the stereotype that a basic electrical machine course is restricted only to transformers, DC brush machines, AC induction machines and wound-field synchronous machines.
additionally to academic research and teaching, the author has been working for over 18 years within the us high-technology corporative business, being directly involved in solution to real problems as design, simulation,
manufacturing and laboratory testing of an outsized sort of electrical machines for energy generation, conversion and utilization.
Supervising young engineers the author is fully aware what the 21st century industry requires from them and the way they ought to be trained to satisfy the stress of employers.
The author wants to leverage his industrial experience to the classroom teaching. The structure of this book is as follows.
Chapter 1 gives a quick overview of electromechanical energy conversion which is required to know subsequent chapters and have a broad vision of operation of electromechanical energy devices in power trains.
Chapter 2 discusses single phase and three-phase transformers utilized in power EE . Chapter 3 considers SRMs because the simplest electrical machines.
It also shows that such machines must operate during a machine-solid state converter environment. Chapter 4 briefly discusses DC brush (commutator) machines.
Nowadays, these machines are gradually replaced by vector-controlled induction and PM brushless motors, therefore the presented material is restricted to fundamentals of ordinary DC brushless motors while emphasis is given to modern brush PM slotless motors.
Chapter 5 deals with armature windings of AC electrical machines with specialise in coils construction, connection diagrams, induced EMF, distribution of the force (MMF), and effect of magnetic saturation.
The reader can familiarize with such terms as winding factors, saturation of magnetic circuit, effect of slotting and effect of upper space harmonics.
This material is crucial to know AC induction, synchronous and PM brushless machines. Chapter 6 on induction machines is that the largest chapter during this book because induction motors are the foremost common machines in industrial, traction, energy systems and public life applications.
This chapter also introduces fundamentals of inverter-fed induction motors. Chapter 7 is dedicated to wound-field rotor synchronous machines with specialise in turboalternators.
This chapter ends with salient-pole rotor synchronous motors, which may be a bridge to Chapter 8 on PM brushless motors.
PM brushless motors are categorized into sine-wave (synchronous) motors and square wave brushless motors. during this chapter the reader also can find fundamentals of inverter-fed PM brushless motors.
