The synchronous generator belongs to the family of electric rotating machines. Other members of the family are the direct‐current (DC) motor or generator, the induction motor or generator, and a number of derivatives of these three. What is common to all the members of this family is the basic physical process involved in their operation, which is the conversion of electromagnetic energy to mechanical energy, and vice versa. Therefore, to gain an understanding of the physical principles governing the operation of electric rotating machines, one has to understand some rudiments of electrical and mechanical engineering.

Chapter 1 is for those who are involved in operating, maintaining, and trouble‐shooting electrical generators. Specifically, those who want to acquire a better understanding of the principles governing the machines' design and operation, but lack an electrical engineering background. The chapter starts by introducing the rudiments of electricity and magnetism, quickly building up to a description of the basic laws of physics governing the operation of the synchronous electric machine, which is the type of machine to which all salient pole hydro generators belong.
