This book is for those who know what electrical machines are and are familiar with classic books on this subject, for example, [1]. We will not repeat the material that is well worked out in classical literature. Instead, in the first chapter we will try to look at electrical machines not from the perspective of the development of specific technology, applications, or competition of industrial players for some market niches, but as the part of Technosphere of our planet. For our research, in the following chapters, it will be suggested to sometimes look at the research subject from different perspectives and imagining ourselves not only in the role of an engineer or a scientist, but also, for example, as philosophers, inventors, etc. So, let’s assume that we have decided to explain what electrical machines are to someone who has never thought about them, doesn’t know what they are, or, at best, has only a vague idea—let’s imagine a child or, even better, a resident of an extraterrestrial civilization. We will use an approach known since ancient times—almost any object can be characterized by the following attributes: appearance, functions, and operating principles, size, the materials from which the object is made, its behavior, impact on humans, relationship with the surrounding world, where the object comes from, and where it disappears to. We will go through this list and at the same time test the strength of some well-known truths in the world of Electromechanics. In the end, we will obtain one of many possible descriptions of electrical machines as objects of the Technosphere.
