Chapter 8: Coil Design and Fabrication

Coil design for induction heating has been developed and refined over time based on the theoretical principles applied in practice to several simple inductor geometries such as the classical solenoidal coil. This chapter reviews the fundamental considerations in the design of inductors and describes some of the most widely used coils and common design modifications. Specialty coil designs for specific applications are also discussed. The chapter concludes with sections devoted to coil fabrication and design of power-supply leads.
