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:
“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)
“The man who knows governments most completely is he who troubles himself least about a definition which shall give their essence. Enjoying an intimate acquaintance with all their particularities in turn, he would naturally regard an abstract conception in which these were unified as a thing more misleading than enlightening.”
—William James (1842–1910)
“The definition of good prose is proper words in their proper places; of good verse, the most proper words in their proper places. The propriety is in either case relative. The words in prose ought to express the intended meaning, and no more; if they attract attention to themselves, it is, in general, a fault.”
—Samuel Taylor Coleridge (1772–1834)
