Microamp Pulse Electric Motor

[@billbailey4615]

The solar cell was a great way to end the video.Thank you for another great on the edge build that is easily replicated.

[@MrDaniyalAh]

Running a motor off just from the light in the room? As an experienced electronics hobbyist I can surely say it is absolutely amazing! Mind Blown! Nice Work Man!

[@chusdiaz9160]

😂😂😂Ahora te vas al balcón a aplaudir 👋👋🤭

[@felixa695]

You have again built a very nice model of an electrical motor. Thank you for sharing 👍🏼

[@felixboian-togyik3346]

notice my name

[@Kapalek84]

Needle and magnet is brilliant idea! Thank you for sharing it! Have a nice day!

[@НикитаПанов-т7к]

Thank you for your efforts! Your videos give us hope)

[@mikeoliver3254]

Very cool design. I am going to have to think about building something like this. The needle and magnet are genius.

[@mrimbusyt]

Nice video

[@bm830810]

so many great ideas, thank again

[@theuniversalbosstheunivers4624]

Nice pulls motor !!!!

[@ludicscience]

thanks

[@harrisjayarajfanharrisjaya1377]

Lol😂😂😂😂😂😂

[@titanxf0150]

Which is the verse of turning of the coils?

[@spandandutta2485]

mind blowing motor...sir very good video

[@theuniversalbosstheunivers4624]

Should all the neodymium magnets be in same size I have those magnets in different sizes. Will it work

[@heavycurrent7462]

The rotor must be balanced and has an even distribution of weight across it, otherwise it will vibrate terribly and cause additional friction. Also, different sizes and shapes of magnet will also have different dimensions and magnitudes of magnetic field. The reed switch will not behave consistently hence, for sometimes it would close early and sometimes late, depending on the magnet that is affecting it. So the coils would not fire accurately either.

[@MsJaffal]

Nice design . Thank

[@jackwoods8061]

Good video, well versed. Thank you.

[@felixboian-togyik3346]

awesome video! keep up the great work!!! :)

[@TechnoW1zard]

What method did you use to wind the thousands of turns? Not by hand I hope

[@ItaloLima]

Very Cool !!

[@BachelderMark]

I would love to see what kind of properties the flyback pulse would have. Perhaps charge a small battery? At least view them on a 'scope.

[@spdas5942]

Which micro ammiter do you use , sir ? Kindly let me know .

[@boyanatanassov9263]

Awesome!!!

[@dragonengineering6444]

You can put a screw in the center of the bobbin to increase the magnetic field also

[@RusselPratt]

This is really pretty

[@t9yt]

Nice 👍. Are all the four magnets set in specific polarity?

[@tonyfremont]

I suspect they are all the same orientation, and the cooks wired such that they produce the same polarity (such as North facing the magnets, with the magnets having North facing away from the rotor. Perfect 90° spacing of the magnets and 180° spacing of coils, combined with careful placement of the reed switch allows adjustment of the speed/power consumption of the motor. Even though the current didn't increase, power consumption doubled when the voltage was increased. By my calculations, at 25uA average, it should run for several years on a single AAA battery.

[@mairavanhun5402]

Coolent?

[@RichardKCollins]

If you would add $Thanks, I would be glad to make a donation to support you doing more of these, with precise measurements and calculations. At 1 volt and tens of microAmperes, this is more properly (or also) a microWatt motor. If you are at 0.5 Volts and 25 microAmperes, that is (0.5 Volts)*(25 microAmperes) = 12.5 microWatts. You can use the rate of rotation of the motor as a precise voltage measure, if you can also measure the current precisely. A solar cell of that size (you should put a link) in full sunlight might be 0.5 Watt and up to 8 volts. I see many about that size but with ratings all over the place. I am looking at one on Amazon that says 100 milliAmpere and 5 Volt which is 0.5 Watt. But that is probably full sunlight rating. If sunlight is about 1000 Watts/meter^2. If your indoor light is at 10 Watts/meter^2 and your solar cell about 2x2 inches (50 mm * 50 mm) or (0.05 meters * 0.05 meters) That is somewhere in the order of (10 Watts/meter^2)*(0.05 meters * 0.05 meters) = 0.025 Watts. The silicon solar cells give about 0.5 Volts so that is (0.025 Watts)/(0.5 Volts) = 0.05 Ampere. And they have varying efficiency. Learning to be precise, write things down, and give links to all your background information - that is a step towards doing good science and engineering. If we really do "solar system colonization" well, it is going to need whole generations of people with different skills, a strong sense of courage, and willingness to work very hard, often in dangerous situations. Monitor closely the room illumination and the solar cell properties. The energy of green light at 520 nanoMeters is 2.38 ElectronVolts. That is only a tiny part of the spectrum. You could use the actual spectrum, and the efficiency of the solar conversion process, and camera data to make measurements - after careful calibration. I just checked and moonlight is about 0.108 lux which is(0.108 lumen/meter^2) or about 600 microWatts/meter^2. The sun is about 2.3 Million times larger than moonlight. Another source says moonlight is about 0.25 to 1 lux. The Internet ( I have studied it intently every day for the last 25 years) is a mess. This sort of basic knowledge ought to be available to everyone, not have to spend days or weeks just qualifying sources and sorting through random stuff. Richard Collins, The Internet Foundation

[@2150dalek]

I need to build a similar device. But when energized to only turn CW and/ on demand- to rotate CCW, - not continuous. I subscribed, and will check out your other videos. Thanks!

[@SatisfyHacks]

Cool

[@valveman12]

I just want to build one to set on my desk in my office.

[@lpq2069]

Saudações Ludic Science. Saudações a todos. O electromagnetismo move o nosso mundo. Tudo de bom.

[@TechnoW1zard]

I wonder if you could power this using a crystal radio tuned to a local station, and a voltage multiplier. Then it could also run in the dark

[@ludicscience]

Nice idea

[@louisrozario6420]

supper idea.

[@dibuasp]

nice

[@PabloPazosGutierrez]

Is it possible to actually use the rotational force generated by the motor on a practical application? Thanks!

[@tonyrebeiro]

Nice video and thanks for sharing. But, what does this video prove? As a toy, it's great, but is there anything beyond this?

[@tonyrebeiro]

@David Wanklyn Yes, there's a lot. Check out Carl Sagan's work, for starters.

[@MrTauron77]

Ez zseniális... Napelemmel egybekötve.

[@robson6285]

With a core in each coil the thing will be so much more powerfull! and with approximately the same current or lower due to the higher induction thus impedance. Just some old screws will do. Now you have a very low efficiency.

[@ludicscience]

No, you can not use an iron core because the iron will attract the magnets and the motor will not rotate.

[@dibuasp]

what is the application of this motor?

[@igrewold]

I was thinking of a tiny ventilation fan. By making blades/fins say with paper, cardboard, ice cream(wooden) sticks, cuts from plastic bottle...etc. Then enclosing that into some case or box with holes for coming air and outgoing one...etc.

[@pacocable]

Muy bueno amigo. Tambien ando liao con motores de pulsos. He hecho unas bobinas como las tuyas con canillas de maquina de coser. Han entrado sobre 300 y pico de espiras de 0.2 mm pero la resistencia es muy muy pequeña y consume mucho. Con otro tipo de bobinas si consigo reducir muchisimo el consumo.

[@justacoffeemakerjr.9813]

with solar panel last forever due existence of light n panel itself but, How long it will last by a single AA battery can it run for a day or less effeciency ?

[@ludicscience]

With AA battery can run for months

[@justacoffeemakerjr.9813]

woww.. Im just imagine a possiblity generate power for something, from this simple ide, thanks for sharing sir..

[@TheBdd4]

Johnpaul minguito, thx for replying. Laurent is a talented guy who helps us with his creativity and insight. His replication of lasersaber's motor accomplished nothing useful. Earlier videos already showed the design does no useful work.

[@theuniversalbosstheunivers4624]

Y not to use metal bobbin

[@ludicscience]

metal will attract the magnet

[@theuniversalbosstheunivers4624]

@@ludicscience Oh Thank you bro

[@zoranpocrnja2646]

Can get the coil from burned light low power neon or led lights!!

[@trench01]

next time put the magnets ontop than on the side so that you can make the coils get closer to it since on the side you lose some due to the shape. ;) Have electromagnet abov and below the magnet migth help a bit more. Also if the center of the core was smaller wouldnt it be better to have more turns?

Školní pokus , nechápu co nám tím chce autor ukázat.

[@qwertyentertainment3349]

Must be really tedious to wind those coils

[@igrewold]

Use a tiny motor with something like a pen/pencil, fixate the core, and turn it on until it is done winding. Or anything that rotates like a drill or food/beverage mixer/blender...etc. Or get this and modify it, say with a metal hanger wire, to your liking: www.aliexpress.com/item/Electric-Mini-Kitchen-Stirrer-Milk-Frother-Coffee-Egg-Milk-Shake-Mixer-Random-Colors/32550800833.html

[@TheBdd4]

Hello Ludic, thanks for uploading this video. You do good work, but why waste time designing another motor that does no useful work. Please put your talent into more practical designs. Thanks

[@Tsnafu]

I'm very late to be adding this comment, but how can you say it does no work? It had delighted and entertained 37,000 people, and inspired some of us to do the same. What use is art is it does no work? To some it seems, none at all
