Surface heating by induction

Electrical Engineering, 1944
Induction heating offers a method for heating of electrical conductors such as steel, brass, graphite, by exposing them to a varying magnetic field. The application of induction heating to melting, forging, surface hardening, and other uses is becoming increasingly common, resulting in a mounting interest for a physical concept of the heating effect ...

The Heating of Induction Motors

Transactions of the American Institute of Electrical Engineers, 1909
The object of this paper is to show the limitations imposed on the designer of induction motors by the heating of the machine, and also to show how this heating may be predetermined.

Induction and Dielectric Heating

Transactions of the American Institute of Electrical Engineers, 1948
Induction and dielectric heating have assumed in recent years an important position in industrial heating; dielectric heating more recently than induction. These unique forms of heating, once responsible only for power losses in electric equipment and machinery, offer many advantages over conventional means of heating by convection, conduction, and ...

Experimental Induction Heating Hypophysectomy

Confinia Neurologica, 2007
The use of implanted metal seeds to induce hypophysectomy using induction heating was studied in vitro and in experimental animals. The preliminary observations indicate that this technique is not satisfactory for bringing about total hypophysectomy at primary operation but may be useful in permitting secondary lesions in the hypophysis at a later date

Heating characteristics of magnetic wood by induction heating

IEEE Transactions on Magnetics, 1999
The purpose of this article is to examine the possibility of using magnetic wood as a heating board. This article covers top and side surfaces of heating characteristics for three types of magnetic wood (impregnated, powder and coating types) when using three different excitation coil types (solenoid, meander and spiral coil).

Transverse flux induction heating

Electrical Engineering, 1950
FOR SEVERAL years following 1941, the author was engaged in the development of radio-frequency induction heating for the flow-brightening of electrolytic tin plate. Lines are in operation today melting the electrolytically deposited tin coating on 30-inch-wide steel strip at speeds of 1,300 feet per minute with a power input of 1,200 kw to the strip ...

Zone Controlled Induction Heating (ZCIH) A New Concept in Induction Heating

2007 Power Conversion Conference - Nagoya, 2007
This paper proposes a new "zone controlled induction heating" (ZCIH) system. The ZCIH system consists of two or more sets of a high-frequency inverter and a split work coil, which adjusts the coil current amplitude in each zone independently. The ZCIH system has capability of controlling the exothermic distribution on the work piece to avoid the strain

Induction Heating - Selection of Frequency

Transactions of the American Institute of Electrical Engineers, 1944
THE general definition of induction heating is the use of eddy currents to raise the temperature of a conducting mass. Thus induction heating is an application of the theory of the eddy-current phenomenon.

Heat treatment of steel with induction heating

Metal Science and Heat Treatment, 1967
Induction hardening makes it possible to obtain a favorable combination of properties, high static strength, fatigue strength, and contact strength with minimal alloying of the steel.
