The design and control concepts have allowed their applications to be expanded into new fields. Power systems, factories, powerplants, electrical vehicles, and household appliances use them as important components. During the process of generating, transmitting, and consuming electric power, the electrical machines are part of the energy conversion process. Industrial, transportation, power systems, and other applications use electrical machines and drives as one of the most important components. As a result, their development is now a real challenge, concentrating on improving efficiency while reducing manufacturing and material costs. A wide range of working principles and topologies are covered in the literature of such devices. In these fields, a large number of specialists are working, seeking both the latest technological advances and publishing opportunities that can reach large audiences.
In the first part of the book, the basic principles of how electrical rotating machines work will be explained. The conditions necessary for sustained electromagnetic torque (Te). The modes of operation in motoring and generating. There will be a primary focus on induction motors, single phase induction motors, and synchronous machines. For a better understanding of rotating machines, it is necessary to have an understanding of distributed windings. Electrical and mechanical angles will be explained. We will discuss the nature of magnetic flux distribution along the air gap of rotating machines. Understanding the operation of induction and synchronous machines requires a clear under-standing of rotating magnetic fields.
