ABSTRACT
The eddy current phenomenon is deeply involved in some electrical machines. The study of this phenomenon gains ground when a conducting medium is subjected to a time-varying field. In electrical machines and devices having magnetic cores, the eddy current phenomenon is quite common. The understanding of the eddy current phenomenon becomes essential in the design of electromechanical clutches, eddy current brakes, solid iron rotor induction machines and self-starting synchronous motors. The penetration of alternating flux into the solid iron also needs proper estimation. The involvement of magnetic cores of different shapes and types in electrical machines demands a thorough study of the eddy current phenomenon. Such a study must encompass induction machines with solid rotors, large plates subjected to single-phase and polyphase excitations. In this chapter, an effort has been made to cover all the above aspects.
