Description
The Yaskawa SGDA Servopack features superior functions and performance. Its compact design allows a volume ratio approximately 1/4 that of the conventional servo amplifier model. The SGDA features an auto-tuning function, JOG operation, various monitoring functions, and a PC monitoring function. It is also compatible with incremental encoders or absolute encoder feedback. The servo amplifier circuit board has been coated with varnish to improve environmental resistance.

Electric motors are so much a part of everyday life that we seldom give them a second thought. When we switch on an electric drill, for example, we conWdently expect it to run rapidly up to the correct speed, and we do not question how it knows what speed to run at, or how it is that once enough energy has been drawn from the supply to bring it up to speed, the power drawn falls to a very low level. When we
put the drill to work it draws more power, and when we Wnish the power drawn from the mains reduces automatically, without intervention on our part.

The humble motor, consisting of nothing more than an arrangement of copper coils and steel laminations, is clearly rather a clever energy converter, which warrants serious consideration. By gaining a basic
understanding of how the motor works, we will be able to appreciate its potential and its limitations, and (in later chapters) see how its already remarkable performance can be further enhanced by the addition of external electronic controls.

This chapter deals with the basic mechanisms of motor operation, so readers who are already familiar with such matters as magnetic Xux, magnetic and electric circuits, torque, and motional e.m.f can probably
aVord to skim over much of it. In the course of the discussion, however, several very important general principles and guidelines emerge. These apply to all types of motors and are summarised in Section 1.8. Experience shows that anyone who has a good grasp of these basic principles will be well equipped to weigh the pros and cons of the diVerent types of motor, so all readers are urged to absorb them before tackling other parts of the book.

I have deliberately not included any computed magnetic field plots, nor any results from the excellent motor simulation packages that are now available because experience suggests that simplified diagrams are
actually better as learning vehicles. All of the diagrams have been
redrawn, and many new ones have been added.

Review questions have been added at the end of each chapter. The number of questions broadly reflects my judgement of the relative xviii Preface importance of each chapter, and they are intended to help build confidence and to be used selectively. A drives user might well not bother with the basic machine-design questions in the first two chapters, but could benefit by tackling the applications-related questions in subsequent chapters. Judicious approximations are called for in most of the questions, and in some cases there is either insufficient explicit information or redundant data: this is deliberate and designed to reflect reality.

Answers to the numerical questions are printed in the book, with fully worked and commented solutions on the accompanying website The best way to learn is to make an unaided attempt before consulting a worked solution, so the extra effort in consulting the website will perhaps encourage best practice. In any event, my model solution may not be the best!
