INTRODUCTION TO ELECTRICAL MACHINES.

This chapter considers the basic working principles of the so-called ‘classical' set of machines. This set of machines represents the asynchronous (induction), synchronous, DC machines, and variable reluctance machines. The latter will be discussed in the book ‘Advanced Electrical Drives' currently under development by the authors of this book. Of these classical machines, the asynchronous machine is most widely used in a large range of applications. Note that the term ‘machine' is used here, which means that the unit is able to operate as a motor (converting electrical power into mechanical power) or as a generator (converting mechanical power into electrical power). The machine can be fed via a power electronic converter or connected directly to an AC or DC supply. [ABSTRACT FROM AUTHOR]
