Several years ago I walked into a death trap house when house hunting. Second floor you would step out of the bedrooms directly onto the first step down with a 90 degree turn after about 3 steps. No railings, tiny platform at the 90 degree turn, lethal stumble after that. Bought a rancher style instead.

I have a strange question. I took the 2 inductors off my 1000w zvs board (the ons with the 6 capacitors) to add heat sink compound. When I put it back, i realized i hadn't marked their orientation. Does the orientation matter? In other words, can they be installed the wrong way around? Kind regards

No, the orientation of the inductors won't matter.

Interesting method. A couple of years ago, I had to make 138 holes TIMES TWO in a pair of super expensive and impossible to find acrylic aircraft windows. I found drill bits designed for acrylic and drilled each hole 3 times to get to the needed size. Tips that worked for me was having new bits and I kept the bit cool and lubed with dish soap. It's critical not to press hard and to go slow when you break through. To say it was very nerve racking is an understatement! I spent a solid week drilling these holes and didn't crack, chip or clam shell a single hole. Each hole was inspected with a prism upon completion. I really doubt I would have tried to melt my way through that acrylic. I just hope I never have to do that again.

Hi, Can a 120V input, 100 khz Induction Heater be converted to 40 to 50 kHz? Thanks
@frenchcreekvalley 4 ай бұрын
I'd say "it depends". Adding capacitance to the tank circuit without changing the system inductance will certainly lower the frequency. for a given work coil, but without knowing how the circuitry can handle the change, you could be in for trouble. And--- some available induction heaters use specialized water cooled tank capacitors making it hard to modify the "C" of the tank without creating new problems. Of course adding inductance to the tank will also reduce frequency. But even that is complicated by not knowing how machine's driver circuitry is designed.

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?
@frenchcreekvalley 5 ай 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.

@frenchcreekvalley 6 ай 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.

(some better ones do give out a spike to help strike the arc though) but they do come very cheap. iv got a little baby one that was only about 30 quid. also iv got a 30a 48v lead acid charger with a tranny, but i thought i could smooth it out with a bunch of big caps that came out of a big old mig welder. i dont know if thats a good idea though either. ill check your site.

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 8 ай бұрын
I understand all that--- but the USA is NOT 400 Hz; as far as I know, 3 phase 400 Hz is used in aircraft and for some CNC spindle drive motors.
@PeterMcDowell-g7n 8 ай бұрын
@@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.
