Recent advances in power electronics and highspeed microprocessors have led to considerable
attention in electrical machines with regard to their applications in industrial drives. This paper brings to the fore, various types of electrical machines, their operations, and applications, as well as the method of determining their parameters. Various ways of protecting electric machines against overloads and mechanical faults are also highlighted.
The purpose of these notes is be used to introduce Electrical Engineering students to Electrical
Machines, Power Electronics and Electrical Drives. They are primarily to serve our students at
MSU: they come to the course on Energy Conversion and Power Electronics with a solid background
in Electric Circuits and Electromagnetics, and many want to acquire a basic working knowledge
of the material, but plan a career in a different area (venturing as far as computer or mechanical

In industrialized countries, distribution systems deliver electricity literally
everywhere, taking power generated at many locations and delivering it to
end users. Generation, transmission, and distribution — of these big three
components of the electricity infrastructure, the distribution system gets the
least attention. Yet, it is often the most critical component in terms of its
effect on reliability and quality of service, cost of electricity, and aesthetic
(mainly visual) impacts on society....
Engineering for sustainability is an emerging theme for the twenty-first century,
and the need for more environmentally benign electric power systems is a critical
part of this new thrust. Renewable energy systems that take advantage of
energy sources that won’t diminish over time and are independent of fluctuations
in price and availability are playing an ever-increasing role in modern power
Like water, food, and air, electrical energy has become an integral
part of daily personal and business lives. People have become so accus-
tomed to fl icking a switch and having instant light, action, or communica-
tion that little thought is given to the process that produces this electrical
energy or how it gets to where it is used. It is unique in that practically all
that is produced is not stored but used instantly in the quantities that are
This book introduces new concepts and theories of Fuzzy Logic Control for the application and development of robotics and intelligent machines. The book consists of nineteen chapters categorized into 1) Robotics and Electrical Machines 2) Intelligent Control Systems with various applications, and 3) New Fuzzy Logic Concepts and Theories. The intended readers of this book are engineers, researchers, and graduate students interested in fuzzy logic control systems.
Electrical machines are almost entirely used in producing electricity, and there are very few
electricity-producing processes where rotating machines are not used. In such processes,
at least auxiliary motors are usually needed. In distributed energy systems, new machine
types play a considerable role: for instance, the era of permanent magnet machines has now
About half of all electricity produced globally is used in electric motors, and the share of
accurately controlled motor drives applications is increasing.
In this chapter you will learn the following:
² The concepts of power, (real reactive and apparent) and power factor
² The operation of threephase
systems and the characteristics of balanced loads in Y and in ¢
² How to solve problems for threephase
