Effects of Induction Heating in Air Gap of Magnetic Wire

Abstract

Induction heating of parts by eddy currents is widely used in mass production due to high speed, localization of the selective heating zone. Improving the efficiency of induction heating of parts in the air gap of the magnetic circuit is associated with the use of surface and edge effects. Through modeling in ANSYS Electromagnetics Suite 19.2. and experimental studies identified patterns of edge effect in the heated parts. To ensure the uniformity of induction heating of small parts and reduce the soldering time, the electrical switch of soldered parts is used, which with the help of device controller forms a secondary circuit with low electrical resistance and high density of eddy currents.
