Electromagnets in tattoo machine

AI Thread Summary
A tattoo machine operates similarly to an old-fashioned doorbell, utilizing coils with a resistance of 2 ohms and a capacitor to create a rapid circuit opening and closing at 105-145 Hz. Heat production in electromagnets can be mitigated by reducing power supply settings, ensuring proper insulation, and minimizing tension on the back spring. The use of different metals in the machine can lead to erratic electricity flow, contributing to overheating. An optimal setup includes 8 wrap coils, 24 AWG wire, and a 47µF capacitor, allowing for versatile use without needing multiple machines. Consistency in machine setup enhances performance and allows artists to focus on their work rather than constant adjustments.

I will keep this brief a tattoo machine is basically an old fashioned doorbell. to coils wired together with a resistance of 2 ohms, generally a 47uf 50v electrolytic axial capactior. the contact is a spring and copper screw. the circuit opens and closes rapidly, 105hz to 145hz. my question is heat produced by electromagnets and the causes and or ways to reduce heat. the yoke is the frame base of the machine which is 1018cr steel as well as the coil cores themselves.

turn your power supply down, you could have unwanted contact between frame and poor insulated wire, you could have scuffed insulation on the wire somewhere in your coil , your back spring could have way to much tension on it causing you to turn up the power, to many different metals being used ie: iron coils,steel yoke, aluminum frame,brass bindings(the different metals have different conductibility rates which causes the the flow of electricity to become erratic as it travels through the machine) chances are if your coils are hot so is your capacitor you may need a bigger capacitor...best way to reduce heat is to require the least operating power, so set up your machines to run at 8v or less the best machine set up is an 8 wrap coils 24awg wire 47uf 35v capacitor 18g springs <-you can set up your machine for anything with this set up(from a cutback liner to a long stroke color packer) all you will have to do is adjust stroke and power rate. think of a machine as an instrument it needs to be "tuned" when your machine is tuned it will have a nice buzz/hum sound and it will feel "consistent" tattooing for a decade now and I have found that my machine set up for liner and shader are the same set up an all around set up but one runs a little faster(my liner) but I can line color or black and gray with either machine. You don't need 4 machine set ups. I tuned a machine for a coworker and that's all he uses is that one machine. He'll do all his lining then he'll switch to a mag and do all his fill one machine. You don't need to know the power supply numbers use your natural senses by ear and touch. In this art you will realize that you hone and refine your skill(hopefully). ou won't set up 4 machines, 2 at most because you learn all the techniques you can do with different needle groupings when using the same machine set up reason being you're always going to know what your machine/s can do ie: like lining with a mag...With all that being said my machine parts set up is what I mentioned above ^ with a medium stroke and ran between 7-8 volts I like to use the same set up with each machine when I switch out I know how the other machine will run and I don't have to adjust my volts on my PS the more I can keep the same consistency in my set up the better and faster you will become because you are not constantly adjusting, any adjusting results in conforming to the machine the more time you have to worry about your machine the less you are really concentrating on the tattoo at hand...
 
Hi all I have some confusion about piezoelectrical sensors combination. If i have three acoustic piezoelectrical sensors (with same receive sensitivity in dB ref V/1uPa) placed at specific distance, these sensors receive acoustic signal from a sound source placed at far field distance (Plane Wave) and from broadside. I receive output of these sensors through individual preamplifiers, add them through hardware like summer circuit adder or in software after digitization and in this way got an...
I have recently moved into a new (rather ancient) house and had a few trips of my Residual Current breaker. I dug out my old Socket tester which tell me the three pins are correct. But then the Red warning light tells me my socket(s) fail the loop test. I never had this before but my last house had an overhead supply with no Earth from the company. The tester said "get this checked" and the man said the (high but not ridiculous) earth resistance was acceptable. I stuck a new copper earth...
Thread 'Beauty of old electrical and measuring things, etc.'
Even as a kid, I saw beauty in old devices. That made me want to understand how they worked. I had lots of old things that I keep and now reviving. Old things need to work to see the beauty. Here's what I've done so far. Two views of the gadgets shelves and my small work space: Here's a close up look at the meters, gauges and other measuring things: This is what I think of as surface-mount electrical components and wiring. The components are very old and shows how...
