Arrangement and method for powering inductors for induction hardening

摘要

An arrangement for induction hardening a part including a pair of separate inductors electrically isolated from each other and configured to substantially surround a part when brought into close juxtaposition with each other. The inductor sections are powered by respective secondary inductor loops brought into close juxtaposition with a primary inductor loop connected to an ac power source which induces an ac current in each inductor section.
