SDF® Induction hardening of a bevel gear Induction brazing of joining copper wires on an electric motor

Presentation eldec

■ Alternating current, that flows through a coil, leads to a time dependent magnetic flux around that coil.

■ The magnetic flux creates eddy currents in a work piece that is located inside the coil .

■ The penetration of the induced current depends on the frequency.■ Eddy currents are generated by the electrical resistance of the

work piece.

1. Physics of induction heating

■ 1982 Founded in 1982 by Dipl. Ing. Wolfgang Schwenk. eldec develops and manufactures inductors.

■ 1993 The product range continues to expand: eldec develops and supplies the first HF and MFgenerators with IGBT semiconductor transistors.

■ 1998 Founding of eldec Induction USA. This facility markets all eldec products, assembles generators

and offers all services for the American markets, Canada, Mexico and South America.

■ 2000 Supply of the first SDF generators. A patented technology which is mainly used for true-

contour inductive surface hardening of gear wheels.

■ 2004 €11 million turnover with the two facilities.

■ 2006 Completition of a worldwide unique pilot hardening system with a 3000 KW SDF® - Generator.
