1000W Induction Heating Part 4: Pancake Coil

Share

  • Published on Oct 24, 2015
  • This is part 4 of my inductive heating series. In this video, I make a pancake coil for inductive heating the surface of parts that wouldn't make sense to build a regular coil for. It can also be used for cooking. Induction cooktops are more efficient than a gas or electric stove because there is less wasted heat.

    Gostaria de saber e agradeço de antemão pela resposta, se é o calor do fogão que estimula a panqueca a liberar energia ou se é por causa da atividade elétrica do fogão que a coisa trabalha ? Pois se for por causa do calor é só acender um fogareiro que não libere demasiado calor.

    Just a side note for those admiring how fast the little cast iron skillet heats up.
    Cast iron is a no-no for regular induction cook tops because they get too hot, overheat and melt the entire induction cook top. The protection does turn it off pretty quickly, so no cast iron in induction.
    Unless you want to get it red-hot or melt the cook top!

      BS! You need to FILL any cookware, be it cast iron or other, on an Induction field. Period. To cook means to cook food, not empty skillets.

    Hello! Brilliant video. Just 2 quick questions: what cooling fan do you use? I hooked one up to mine yesterday and I fried it's motor as it was only a 12V rated one! Secondly - do you connect it straight to the power supply or do you incorporate it into the ZVS board?
    Thanks!

    Seems like you could make a low voltage on demand water heater with this. You should do it and undercut the expensive ones on the market. Make them for RVs

    • George Komáromi
      George Komáromi 8 months ago

      I was thinking the same, my idea is using the tube induction coil, fitting it around a steel/iron pipe and it would flippin' heat the water while it passes through, bloomin amazing. Though it would drain a lot of electricity, so i dont know how efficient is this or how much do we really need this much heating power in an RV, but in a household application this is as good as is gets, water heating without reservoir is good for space saving as well for small apartaments...though i dont know if this kind of zvs could hold up for a continuous 20 min drain on 50V 15A

    will it warm the iron in your blood?

  • Migueldeservantes

    Well I guess that me been the ignorant on the room, may I ask you, if there is not a metallic object in the proximity of your pancake inductor there is not amperage or voltage draw?? and I guess that the second question will be, can it be projected to work in only one direction? Just don't understand how it can't be consuming power when there is not metal next to it...

    • Proto G Engineering
      Proto G Engineering  Year ago

      A ZVS driver is a self oscillating circuit so it is drawing current when there is not metal nearby.

    • Proto G Engineering
      Proto G Engineering  Year ago +2

      yes, they have induction cooktops at Costsco and other stores but those are much lower frequency so they can only be used for cooking and not other things like heat treating steel. The lower frequency results in much more even heating, which is good for cooking. Higher frequency will start to be affected by the skin effect and heat the outside surface of the object much faster than the inside which is good for heat treating.

  • Lance Hobby

    Thanks for this video. It helped me with my induction heating start.
    Here's my question. Will a longer length of Litz wire pull more amperage or is it really dependent on the part?
    I ask as I might run multiple induction circuits as I will be wrapping around the outside of a 12" diameter pot. I'll surely know the answer once I try it but I'm trying to save myself from splicing expensive Litz wire in half...
    I'm curious if I could wrap the hight of the 8" of the pot (yes it will be a lot of wire) or if I'll have to split it between two systems and do 4" x2.
    Thanks for your videos! I think you're doing a great service to help the rest of us tinkering around...

    Is that copper tubing or solid copper wire and do you just connect a positive and negative to a 12-volt feed to power it? It almost looks like 3/8 inch copper tubing but I'm not sure and is it just copper spoiled and then positive to negative it will not harm my batteries or anything?

    I'd like to make a 12 volt (dc battery 12.8-14.5 volt) coil for heating a cafetière or small teapot, is 12 volt enough, I'd like to consume between 500-1000 volts to avoid staining my batteries and run direct from the battery, do you think this is feasible and do you have any suggestions such as wire gauge?

    If you have to cool the components, then how could this save energy? I'm just asking... My mind is saying why bother if it leeks energy!?

    • Proto G Engineering
      Proto G Engineering  2 years ago

      Induction is more efficient than electric stoves and much more efficient than gas stoves. Induction cooktops are 80%+ efficient, electric stove tops are 70-77% efficient and gas stoves are about 40% percent efficient. Induction cooking is more efficient and faster than both. Not as cheap though.

    • Coletta Hughes
      Coletta Hughes 2 years ago

      Thank you for that great information Proto G, I'm not concerned with the energy cost of the little fan, it's heat leaking off the electronics. I'm just wondering is it less than the 60% heat loss with gas? Mind you I'm all for induction due to speed and safely, but I'll always have at least a single gas burner for gourmet cooking.

    • Proto G Engineering
      Proto G Engineering  2 years ago +1

      Let's just look at an electric stove top. First, you have to heat a resistive element up that then transfers heat to your pan. Induction is substantially faster because the heat is directly transferred the pan and some of that heat leaks back to the coil from the pan. Using a 1-2 Watt fan to keep things cool isn't really a big deal when compared to the 1000 Watts the machine is using. A more industrial machine would use much more expensive components with lower switching losses and better thermal properties.

  • garyworks
    garyworks 2 years ago +3

    Great video, but I just want to point out to those viewers who don't catch it that you used Litz wire, which avoids skin-effect losses that you would have with regular stranded or solid wire by using hundreds of strands of insulated fine wires, and is the only reason your coil doesn't get hot. The link you provided for it lists it as 5 bundles of 108 strands of insulated #36 wire, #36 being good to 50kHz and somewhat beyond. And guessing at the size of your coil, I'd say it is at least a few dozen microhenries, probably much greater than the stock coil and therefore shifts the resonating frequency much lower (by about 2/3, I'd guess?), which is not a bad thing as long as you don't go so low that the heating becomes inefficient; the resonating caps, which are what is usually the most stressed in inductive heaters, will run cooler and have lower losses. Good job!

    Hi Proto G. first of all a million likes for your video.... u truely are an inspiration. atleast for me. this video is amazing. however if u can clarify one doubt for me. what material did u use at 0.33 to cover the coil???? awaiting your answer... once again thanks for the video...

    I am thinking of making a sort of molding machine by wrapping some of the his Litz wire around about 1" pipe and having it heat up to about 350-450F, any suggestions on how to control temperature and what kind of spacing to use? The link you provided for Litz wire it's 56 bucks for 5 feet and it's 9 gauge, can a smaller gauge be used because it's much much cheaper on eBay.
