Energy efficiency of machines for surface hardening

Based on increasing prices for energy and growing consciousness for ecology, the energy efficiency of machines has become an important aspect in many sectors of the industry. The significance of the efficiency factor of induction heating systems, which are generating power ratings up to the megawatt-band, has risen up eminently. Due to increas-ing needs on reliable solutions and high requirements for the components, induction as a tool for surface hardening obtains high demands.
