Definition
The term "RF induction" is traditionally used to describe induction generators designed to work in the frequency range from 100 kHz up to 10 MHz, in practical terms however the frequency range tends to cover 100 to 200 kHz. The output range typically incorporates 2.5 to 40 kW. Generally, the induction heaters in this range are used for smaller components and applications such as induction hardening an engine valve.
The term "MF induction" is traditionally used to describe induction generators designed to work in the frequency range from 1 to 10 kHz. The output range typically incorporates 50 to 500 kW. Induction heaters operating within these ranges are normally utilised on medium to larger components and applications such as the induction forging of a shaft.
The term "Mains (or supply) frequency" is traditionally used to describe induction coils driven directly from the standard a.c. supply. Most mains-frequency induction coils are designed for single phase operation, and are low-current devices intended for localised heating, or low-temperature surface area heating, such as in a drum heater.

Famous quotes containing the word definition:
“Perhaps the best definition of progress would be the continuing efforts of men and women to narrow the gap between the convenience of the powers that be and the unwritten charter.”
—Nadine Gordimer (b. 1923)
“The very definition of the real becomes: that of which it is possible to give an equivalent reproduction.... The real is not only what can be reproduced, but that which is always already reproduced. The hyperreal.”
—Jean Baudrillard (b. 1929)
“It is very hard to give a just definition of love. The most we can say of it is this: that in the soul, it is a desire to rule; in the spirit, it is a sympathy; and in the body, it is but a hidden and subtle desire to possess—after many mysteries—what one loves.”
—François, Duc De La Rochefoucauld (1613–1680)
