Induction Heating Demonstration

at 5:44 am. Filed under Crazy Hacks, DIY Hacks, Electronic Hacks, Insane Equipment

Richie Burnett has a Induction Heating Demonstration that is worth having a look at. Richie has also done extensive work with Tesla coils, make sure you have a look at those also.

“Induction heating is a non-contact heating process. It uses high frequency electricity to heat materials that are electrically conductive. Since it is non-contact, the heating process does not contaminate the material being heated. It is also very efficient since the heat is actually generated inside the workpiece. This can be contrasted with other heating methods where heat is generated in a flame or heating element, which is then applied to the workpiece. For these reasons Induction Heating lends itself to some unique applications in industry.

How does Induction Heating work ?

A source of high frequency electricity is used to drive a large alternating current through a coil. This coil is known as the work coil. See the picture opposite. The passage of current through this coil generates a very intense and rapidly changing magnetic field in the space within the work coil. The workpiece to be heated is placed within this intense alternating magnetic field.”

    What is the science behind it? Eddie currents?

  2. Jared Says:

    Awesome!

  3. joebob Says:

    wow..

  4. Charlie Says:

    A very useful project for DIY hackers
    considering you show us a complete schematic
    leaving out all the details and begging people
    not to ask for more info. Don’t waste our
    time, spare us your ego trip and just keep everything to yourself.

  5. Mmeval Says:

    I agree Charlie. Why put this numnuts on a site that is for DIYers?

  6. Joven Says:

    Hmmm, interesting thoughts and project.
    I look at the numbers given for current,
    frequency, capacitence and inductance… and that’s all i need.
    I could build this, cause the numbers make sence.
    If you can’t figure it out with what’s given,
    then you don’t need to be playing with high voltage.

  7. David Says:

    Not sure what Charlie and Mmeval are going on about. The schematic and values given are more than enough for someone competent in power electronics to construct it. Joven is right on the money. If you can’t build it from this you would probably kill yourself anyway.

    Hmmmmmm I love the arrogant “Oh if your not a know it all – then your a nothing” attitude…

    Half an explaination is not an explaination.

    I tend to feel shitty about highly enlightened – who leave incomplete paper trails and the toadies who subscribe to that bullshit.

    I while I can follow the pix, I also believe a clear and complete schematic with a few “hazard notices” would probably give people the start they need to make the jump from leaning towards “interested and not that expereinced”, to that of “capable and understanding”.

    The worst teachers in the world are the ones who cannot explain their own subject clearly.

  9. callmeshane Says:

    I also want to point out that there is no INFO on the power supply or source, nor is there anything about the HF choke…

    Well Duhhhh…

    Shit canning the people who want to learn but who are not very good at laying guessing games – because of the authors poor and incomplete information – is just slack buck passing…

    It’s like George Bush, robbing and killing lots of people all over the world and when they take him and his idiot supports on, he brands them “terrorists”…

    The logic just doesn’t quite add up.

    sir i have one portable induction heating machine thats make SHUNGPING , in that machine control card 5 Nos intergrated circuit built, but all IC name removed ,
    i purchased 5 machine from out sources, now there are not giving services,if they are given exp too high that i can’t affourd,4 IC are 8 pin one IC are 16 pin , if you have any idea about that IC please kindly give that IC No

    please send my E-mail kayurananth@yahoou.co.in

    […] have featured DIY Induction Heaters here before. There is something about heating a big chunk of metal with no contact that is so […]

    DEAR SIR,

    MY MAIL ID kkravi8@rediffmail.com small induction instant water heater details and circuit details if possible mail to my id please

    Regards
    Ananth

  30. Cacci Says:

    Its agreed theres a poor job of explaining the actual way this induction heater works. For example, the recommended caps and the ones he uses are different, the driver and mosfet circuits are nonexistant, etc… However, that does not help the people who want to build the heater. So, if you know a good link on how to do something like this, post it here. http://www.penguinslab.com/induction.htm does a good job of explaining it, but the design is pretty different and not that reliable, he says he blew out part of the circuit in one of his runs. Any info is welcome.

  31. dave Says:

    Why is it so damn difficult to get a circuit of a decent induction heater..is there some secret society who dont want people to make their own stuff, I have been stuggling to find a decent circuit WITH components values to build my own Induction furnace..I mean you have got to do it today with Terribubble expensive inducton generators..Can anyone help an old timer with a desire to know stuff about metals ? well if you can I am prepared to pay for the info/circuits.
    Thanks..Dave Bradbury..UK

  32. Ananth Says:

    Dear Sir,
    I required one small instant water heater Electronic induction type with a tube so that we can pass the water through the tube and when it reaches out the required temp is obtained any small circuit can you give sir.

    Sounds to me like a bunch of liberals wanting people to build something thay want and then give it to them for free! America wast built on innovation, trial & error and just good houspa (getting it done for you lib,s) Or other wards get off you ass and figure it out!
