Re: induction heating
What sort of componets are needed to build a switching power supply as you speak of? Where can I get a schematic for this power supply? How does what you describe provide multi-frequency high amperage current?

Re: induction heating
What are you using for a power supply....voltage/frequency/phase. How do you know the correct # of wire wraps relative to the above power source?

Re: induction heating
No I want an induction type furnace cause who knows what other metals I might want to cast? The price of the componets shouldn't be a problem if I construct this myself. Best I can tell right now I need between 15 & 50 KW to melt approx 25# of metal in a reasonable amount of time. I'm not curren...

Re: induction heating
I suppose one could use some sort of frequency generator as a driver if you could flucuate the high current with the frequency. The higher the amps the better The one I want to build I would think would draw 230V AC @ 60 amps. The high frequency relates to skin effect heating VS a deeper heat when a...

Re: induction heating
Inductive heat relates to heat generated via induction . Similar to how a transformer works. Resistive heat refers to heat generated via current flowing through a resistance. Microwave heat comes about because of a harmonic vibration set up between a particular molecule ( typically water ) and the f...

Re: induction heating
Yes but that is resistive heat not inductive. Real precious & refractory metal foundaries use inductive heating to melt metal which as I understand it now uses eddy currents & hysteresis losses to heat the metal. ( this process is also used for non-contact heating of metallic objects) There ...

induction heating
Anyone out there know anything about how to build a small induction heater/furnace for melting small quanities of metal?
