JO-MAR Industries invites you to stop by!
Induction Heat Treating Coils:
Induction heat-treating coils are often the most effective processes
available for many functions including surface hardening, through
hardening, tempering, stress relieving, and annealing.
Induction heat-treating can be performed in a very short time, with
extremely high efficiency. The ability to in-line heat treat, with high
productivity, less distortion and a clean working
environment are well known benefits of heat treatment by induction.
JO-MAR Industries, Inc. manufactures a number of standard induction
coils and custom made induction coils for the heat treating process.
What is an inductor and how does an inductor behave?
Inductors:
Inductors are closely related to capacitors; the rate of current change
in an inductor depends on the voltage applied across it, whereas the
rate of voltage change in a capacitor depends on the current through it.
The symbol and defining equation for an inductor is
where L is called the inductance and is measured in henrys (or mH,
uH, etc.) and "di/dt" is the change in current over a small period of time.
Putting a voltage across an inductor causes the current to rise as a ramp
(for a capacitor, supplying a constant current causes the voltage to
rise as a ramp; 1 volt across 1 henry produces a current that increases
at 1 amp per second.
The symbol for an inductor looks like a coil of wire; that's because, in its
simplest form, that's all it is. Variations include coils wound on various
core materials, the most popular being iron (or iron alloys, laminations, or
powder) and ferrite, a black, nonconductive, brittle magnetic material.
These are all ploys to multiply the inductance of a given coil by the
"permeability" of the core material. The core may be in the shape of a rod, a
toroid (doughnut), or even more bizarre shapes, such as a "pot core"
(which has to be seen to be understood).
Inductors find heavy use in radiofrequency (RF) circuits, serving as RF "chokes" and
as parts of tuned circuits. A pair of closely coupled inductors form the interesting
object known as a transformer.
An inductor is, in a real sense, the opposite of a capacitor.
What is a transformer and how does a transformer behave?
Transformers are used when voltage is required to be stepped up or down, or to
isolate one AC circuit from another while coils introduce inductance into AC circuits.
JO-MAR Industries, Inc. does quality repairing or complete rebuilding of
Induction Heating Transformers, regardless of their original manufacturer.
