Induction Heating Coils Design and Basic

HLQ Induction EQUIPMENT CO.,LTD Induction Heating Coils Design and Basic In a sense, coil Design for Induction Heating is built upon a large store of empirical data whose development springs from several simple inductor geometries such as the solenoid coil. Because of this, coil Design is generally based on experience. This series of articles reviews the fundamental electrical consider- ations in the Design of inductors and describes some of the most common Coils in use. Basic Design considerations The inductor is similar to a transformer primary, and the workpiece is equiva- lent to the transformer secondary (Fig. 1). Therefore, several of the charac- teristics of transformers are useful in the development of guidelines for coil Design . One of the most important features of transformers is the fact that the ef- ficiency of coupling between the wind- ings is inversely proportional to the square of the distance between them.

tively low efficiency, they may need very high generator power to produce shallow heating depths. Coil characterization Because magnetic flux tends to con- centrate toward the center of the length of a solenoid work coil, the heat- ing rate produced in this area is gen- erally greater than that produced to- ward the ends.
