  I made this coil 3/4" ID following Tech Dregs instructions and it takes less then 5 seconds to make 223 case glow with 360W power and less than 2 seconds with 800 Watt power. Using Chinese 1000W ZVS board and 3/16 tubing.

  Good afternoon, your videos are very interesting. I have a 2500W induction machine and I would like to ask you if it is possible to use a 150 ml crucible instead of the 70 ml that comes with the machine?

• 
  @frenchcreekvalley3 күн бұрын

  The 70 ml graphite crucibles with "SiO2 liner" that I use barely fit into the coil that comes with the machines that I have. You would have to make a larger coil as a minimum. I am not certain about the current requirements for that much larger crucible. Sorry that I can't be more helpful. My guess is that if the 150 ml graphite crucible was full of copper, the current draw on the system would be too high and the unit would fail.

  @frenchcreekvalley26 күн бұрын

  More than you will ever want to know about these heaters can be found on my website, here: spaco.org/Blacksmithing/ZVSInductionHeater/1000WattZVSInductionHeaterNotes.htm The short answer is that those 1000 watt boards come with a work coil that is somewhere between about 1 1/2 inches and 2 inches in internal diameter and have about 7 turns. This gets you an operating frequency of a bit less than 100 kHz. They are usually made from 6mm outside diameter copper "refrigeration tubing". But I almost always use 1/4 inch diameter (USA) copper tubing. I hope this helps. If not, feel free to ask questions.

  VFD means Variable Frequency Drive. Induction motors require a change in frequency to change speed, unlike a DC motor where you just change the voltage applied to the motor to change speeds. When your induction motor is running at full speed the drive will supply it with a 60Hz signal. To slow the motor down it will increase the frequency of the signal. The 400Hz setting is the maximum frequency the drive will apply to the motor, this will result in minimum speed of the motor. That's why the default setting is set to 400Hz. You can change it to higher or lower depending on what speeds you want your motor to run at minimum and maximum. There are limits to how much you can change the settings. For most induction motors in Canada and the U.S.A. 60Hz to 400Hz is standard. You said you didn't understand why the setting was default to 400Hz. This is why.

  @@frenchcreekvalley I did not say that the standard voltage in the U.S.A. or Canada is 400Hz. I DID NOT SAY THAT. The power going in to the VFD from the source is 60 cycles per second. The VFD creates it's own waveform from the VFD to the motor in 3 phase. The 400 Hz is not on the incoming line it is only between the VFD and the motor, nowhere else. The VFD varies the frequency of the signal to the motor from 60Hz (full speed) to 400Hz (slow speed), and other frequencies in between. There is an inverse relationship between frequency and motor speed. That is why they call it a variable FREQUENCY drive.

  The following isn't statement of fact, I'm muddling through my own experimentation in a similar area but with different materials, so these are more like questions. I have limited experience in the field of electronics... Question:- Having two coils in series significantly lowers LC resonant frequency, so once you reach Curie temperature, you can't drive much more energy into the workpiece. You need to reach higher frequencies and that requires a smaller coil (or smaller tank cap/s with much higher power rating?) You should be aiming for higher frequency (skin effect) so should use smaller single coils and keep the work moving to compensate for smaller coil area? Or.. you could get a 10+ KW system and just thrash the energy into the workpiece? On a budget, two smaller, separate systems running in parallel with different coil shapes might be a better setup? Ironically, my brother has a masters in electronics so I should ask him.... but we haven't spoken for years. :/ I'm experimenting with inductively heating non-ferrous metals and it was very interesting following you through this video. I learned a lot, thank you! 🤗

  IMNSHO,Higher frequences seem to be more appropriate for nonferrous metals. You have to look carefully at the info out there to acurately see how this works. Re: "Or.. you could get a 10+ KW system and just thrash the energy into the workpiece?" Answer: Yup! Re: "On a budget, two smaller, separate systems running in parallel with different coil shapes might be a better setup? " Answer: Maybe. But those "15KW" (really about 7.5KW) units that are all over the internet do a pretty good job. Example: www.ebay.com/itm/335031067466? I hope this helps.

At least before Hollywood and corporate America started programming everyone that the kids should all aim to grow up and move away, get to the big city and "make something of yourself". Surviving the country into infirmity depended on the kids starting to take over the heavy lifting at some point.
