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!
