Back Matter Pages About this book Introduction This book aims to offer a thorough study and reference textbook on electrical machines and drives. The basic idea is to start from the pure electromagnetic principles to derive the equivalent circuits and steady-state equations of the most common electrical machines in the first parts.
Although the book mainly concentrates on rotating field machines, the first two chapters are devoted to transformers and DC commutator machines. The chapter on transformers is included as an introduction to induction and synchronous machines, their electromagnetics and equivalent circuits. Chapters three and four offer an in-depth study of induction and synchronous machines, respectively.
Starting from their electromagnetics, steady-state equations and equivalent circuits are derived, from which their basic properties can be deduced. The second part discusses the main power-electronic supplies for electrical drives, for example rectifiers, choppers, cycloconverters and inverters. Much attention is paid to PWM techniques for inverters and the resulting harmonic content in the output waveform. In the third part, electrical drives are discussed, combining the traditional rotating field and DC commutator electrical machines treated in the first part and the power electronics of part two.
Field orientation of induction and synchronous machines are discussed in detail, as well as direct torque control. In addition, also switched reluctance machines and stepping motors are discussed in the last chapters. Finally, part 4 is devoted to the dynamics of traditional electrical machines. Also for the dynamics of induction and synchronous machine drives, the electromagnetics are used as the starting point to derive the dynamic models.
Throughout part 4, much attention is paid to the derivation of analytical models. But, of course, the basic dynamic properties and probable causes of instability of induction and synchronous machine drives are discussed in detail as well, with the derived models for stability in the small as starting point. In addition to the study of the stability in the small, a chapter is devoted to large-scale dynamics as well e.

Guru and Huseyin R. Electric Machinery and Transformers have been written for students at the junior-senior level studying various types of electrical machines. Based upon many years of teaching experience, the textbook is developed in such a way that it provides maximum flexibility without any loss of continuity from one topic to another. We feel that this approach would enable an instructor to easily adapt the material to meet the requirements of a course in electrical machines. For institutions that are on a quarter system and offer only one course in electrical machines, we suggest that they concentrate more on the fundamentals and budget the time for the advanced topics. The textbook concentrates on the basic operation of each machine and tends to minimize the nonessentials.

Modeling of Iron Losses of Electrical Machines and Transformers Fed by PWM Inverters Abstract: With the development of power electronic techniques, pulse-width modulated PWM inverters are widely used to control electrical machines, to feed transformers and to interface renewable energy systems. There are abundant high frequency harmonics in the output voltage of a PWM inverter, which increase the iron loss and result in a de-rating of the machine or transformer.
Preface Electric Machinery and Transformers has been written for students at the juniorlsenior level studying various types of electrical machines. Based upon.
A transformer is a passive electrical device that transfers electrical energy from one electrical circuit to another, or multiple circuits. A varying current in any one coil of the transformer produces a varying magnetic flux in the transformer's core, which induces a varying electromotive force across any other coils wound around the same core. Electrical energy can be transferred between separate coils without a metallic conductive connection between the two circuits.
Electrical Machines Notes References. Hi, thank you for such a brilliant post.
Guru, Huseyin R. It begins with a review of the fundamentals of circuit theory and electromagnetics and then introduces the concept of electromechanical energy conversion. The text not only provides a systematic development of a model for each electric machine based upon established principles and basic laws, but also introduces students to applications and advanced topics. It also includes information on the construction of each electric machine. Electric Machinery and Transformers, enhances student learning of the basic operating principles of electric machines by using numerous supporting examples, review questions, illustrations, exercises, and chapter summaries. It encourages intuitive reasoning for problem-solving over the rote memorization of equations and procedures.

Ранняя юность Грега Хейла не была омрачена криминальными историями, поскольку он провел ее в Корпусе морской пехоты США, где и познакомился с компьютером. Он стал лучшим программистом корпуса, и перед ним замаячила перспектива отличной военной карьеры. Но за два дня до окончания третьего боевого дежурства в его будущем произошел резкий зигзаг. В пьяной драке Хейл случайно убил сослуживца. Корейское искусство самозащиты, тхеквондо, оказалось в большей мере смертоносным, нежели оборонительным. Военной службе пришел конец. Отсидев некоторое время в тюрьме, Хейл занялся поисками места программиста в частных компаниях.
