🤣😂🤪

So many variants!

Lol :)

Impressive work in all your videos very well explained , thank you very much for share with all...this motor can run conected to a source of static current to , with a ground conection ?

foupana Thanks. What do you mean by static current? I recently released a video showing how to run this corona motor using triboelectricity, which is a way of charging something electrostatically. You can see that video here kzfaq.info/get/bejne/bN5md9SBsZeYqYk.html

Thanks my friend,is my error i have make a confusion loking to your motor, and i thinking in other ...my question is about an opinion that i have that we can use a LITLE of DC power (Volts and Amps),to produce a hudge quantity of (high voltage) , than this type of motor is very importante , conected to high voltage , source: sucking of the air or other ways like a big wimshurst machine, but in resume the idea is with high voltage put in rotation a motor with a flywheel that produce more Amps that we need to put in (to extract), to run for example the wimshurst but with some modifications in the type of the rotor and capacitor's, regulating the spark to be more fast as possible and more power , maybe we can run a very important motor generator of DC power out , use an inverter , charge bateries 24 h a day... in my research about rotors i have see that is possible to make them anti-gravity with the repulsion of magnets, and in one side o axe"rotor" a metal sephere in contact with a glass , (reduce the quntity of friction) and the amps that we need to a good rotation "velocity"will be more low, in my opinion probably with a flywheel to asist the 2 disc's of the wimshurst machine is better , anti-gravity technic and without bearings , only glass and spheres "speaking about the type of rotor"... thanks for your time keep the good work my friend, i consider extremely important people like you that educate and help others in many ways, like the (the production of electricity) . if you need to ask something you can contact me in the facebook : Name :(João Cantinho) Country: Portugal

foupana You can use a small DC power (voltage x amps) to produce a high voltage but at the same time the amps will be made smaller. With the losses, the output power will be less than the input power. You always need an external energy source to get more out. I don't know if you have built things yourself, but if not, try building your ideas and you'll quickly learn the limitations.

thank you,!

Thanks. It's lot of work but doesn't seem like it since it's done one step at a time.

So is the coronavirus

Bro I hope that's sarcasm lol

Thanks! Yeah, since this was the one on making, I figured I'd do easy on the demos... so no running in the dark :).

Yeah, it really moves when powered with my cube power supply!

Just saw a video from him about it

Thanks. It turned out pretty nice.

The blades resting on the rotor would introduce "drag" on the rotor. This likely preventing it from turning at all, as there is very little torque available during start up due to the small or limited amount of current flowing through the device. The demonstrated torque produced while spinning is of course the effect of the mass of the moving rotor assembly.

It's hard for me to say. There's probably a trade-off point somewhere where increased losses from more blades will start to mean less power.

Akshat Ahuja I have an explanation of how it works on my website here rimstar.org/science_electronics_projects/corona_motor_electrostatic_atmospheric_motor.htm. The doping isn't absolutely necessary - most people don't do it at all. It's just an enhancement.

Could be. With needles there's less charge area to repel and attraction the charged areas of the cylinder. But I haven't redone my efficiency test for this one yet... it may also be < 1% efficiency.

Nope, I don't have any formulas or tips. I just went on intuition. For all I know, double the number I have might be better. Another variable might be the amount of current your power supply has to offer. I give an explanation of how the corona motor works near the end of this video kzfaq.info/get/bejne/aNiGl6iZ3rO2ZnU.html where I powered it on atmospheric electricity.

Thanks for the reply! Yeah, there is not a lot of information about them online. I will experiment and post my findings. Thanks again!

I don't know. I've no experience with a flyback from a plasma TV. Maybe someone else here knows?

Sure, I harvest atmospheric electricity with it in this video here kzfaq.info/get/bejne/p86Iq7Zy25zWfZs.html and explain it here kzfaq.info/get/bejne/aNiGl6iZ3rO2ZnU.html. Note that this is not an electromagnetic motor so it does work with an antenna. Antennas receive electromagnetic waves. This motor works using high voltage and electrostatics instead. So the wire used for atmospheric electricity isn't called an antenna, it's just a long wire collecting charge from higher up in the atmosphere. I don't think the type of metal used makes any difference. And insulating the antenna up to the peak point is what I did. The wire has an enamel coating on it which insulates it. However, I do wonder if having more of the wire be uninsulated near the top end might collect more charge.

There is a maximum voltage that will exist - that's the voltage required for breaking down the air in the gap between the blades and the surface of the cylinder. The voltage won't go any higher than that. So I guess once you determine what that voltage is then you can do something like you suggest and tune your supply to better match.

I don't see how it would work. There wouldn't be any energy source. Electrets themselves aren't a source of energy.

Muneer Arif In my experience with these bearings, adding lubricants like oil has the opposite effect. The I linked to explains the purpose of the lubricant. Some say that graphite makes them work more freely but I haven't tested that myself.

Muneer Arif There isn't a lot of force to turn the rotor (the jar) so it has to turn fairly freely. Dry ceramic bearings are good for this. Most grease filled bearings don't turn freely enough, though you could try the trick I show in my video "kzfaq.info/get/bejne/nMqmhal2m56UpWQ.html" to remove the grease and make them turn more freely.You could do without bearings if you can find some other way to make the rotor turn freely. I do that using a pen in my corona motor version 1 which you can see here "kzfaq.info/get/bejne/odmgkrKQlr3RpnU.html".The wood I use is pine because it's easy to cut. Any type of wood will work.

If you mean, can the corona motor be powered by batteries, the answer is no. It needs a high voltage, probably in the thousands of volts.

Already done! Check it out here kzfaq.info/get/bejne/hpacjL2l3524imQ.html

Increasing the number of antennae would increase the current, not the voltage. But that's okay, that would still mean more power. The voltage is increased by going higher. I don't really have a good answer regarding the blades, there seem to be a lot of variables there.

At someone's request, I drew up the plans for the two end pieces and made them available for a reasonable $5 (to support this channel) on my Etsy store here www.etsy.com/ca/listing/630576535/corona-motorelectrostatic-motor It sounds like what you're looking for. I don't know where you can get it cut though. Maybe look for a makespace/hackerspace in your area or possibly a school with a wood shop.

It's Bicycle by Kevin MacLeod (incompetech.com).

Sorry, I don't have any torque data for the Wimshurst machine.

Thanks. I've never measured it. However, it can't be much since in this video I show powering it using the Triboelectric effect kzfaq.info/get/bejne/bN5md9SBsZeYqYk.html. With that the current is very small. The gap size between the blades and the cylinder set the voltage limit, probably only one or two thousand volts, but with the small current I'd say the power is in the micro to milliwatts. It is a low torque motor though.

Miliwats?! Thats great efficiency!

Akshat Ahuja I don't know. I'm not familiar with those voltage stabilisers.

how do i use the pvc pipe and cotton facecloth to produce a high voltage??? if i bring a wire close to the charged pvc pipe then where will the other wire go ???

Akshat Ahuja The other wire goes to ground. I have a sections on different grounding tricks in these two videos: kzfaq.info/get/bejne/h9hzmtebv93ScmQ.html and kzfaq.info/get/bejne/fsCKoK6Lr9ith2Q.html.To do the PCV pipe and cotton cloth technique, 1st make sure the end of the wire ends in a sharp point. I find that to get it to work I have to put the PVC pipe near the sharp point as I'm rubbing the cloth on the pipe. It doesn't work if I rub the PVC pipe and cloth vigorously for a while and then move the pipe near the sharp point. So for every every part of the stroke when the cloth is away from the part of the pipe that's near the point, the motor should get some charge.

+Onur Cevik Wax is a good alternative, you can melt wax onto it. Epoxy/resin is also good and will last longer than wax since wax can come off easily. Wherever there are sharp edges there is a stronger electric field than where there is a flat surface. Because of that stronger electric field, charge can leak off from there. But the only place you want charge to leave the blade is at the sharp edge facing the cylinder. So by insulating those other edges you reduce some losses from leakage.

Muneer Arif I gave you a link to where you can buy them on ebay in my reply under my other video. Here it is again www.ebay.com/itm/261462513315?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1497.l2649 They ship internationally. Roller blade bearings might work if you remove the grease from using the method I pointed out in this video kzfaq.info/get/bejne/nMqmhal2m56UpWQ.html But I've never tried it with roller blade bearings so I can't promise it will work.

BGT Productions The charge doesn't get to the foil inside the jar. However, the charge does move around on that foil wherever there's a blade on the outside of the jar. There is an electric field between those charges on the foil and those on the blade, since an electric field isn't blocked by the plastic dielectric. That electric field is added to the electric field between the blade and charges on the surface of the plastic, resulting in an overall stronger electric field. That stronger electric field helps move charge between the blade and the jar.

BGT Productions Yes, for this one you need a corona between the blades and the outer surface of the jar. That's how the charge is moved from one to the other. Or I guess you could say that the corona is largely the charge that is moving from one to the other. For electric fields alone to work I guess you could make a different machine with a different power supply that would use high voltage pulses to produce motion by repulsion without charge transfer. I don't think a smooth surfaced jar wouldn't work. You'd probably need the jar to have a sawtoothed surface and turn on the field only when the next diagonal surface arrived. Hard to describe in words and I'm making it up as I go, but I think something could be done.

Christopher Smith Yup. There are a few videos around that do it but mine using a pipe and rag is here kzfaq.info/get/bejne/bN5md9SBsZeYqYk.html. It makes use of the triboelectric effect.

The voltage is required to be able to ionize air across the gap between the blades and the plastic and to provide some Coulomb force for the repulsion. I'd guess at least the low thousands. You'd need current too but as you can see in my other video here, kzfaq.info/get/bejne/adpnodN-qN7NhqM.html I managed to turn it using just triboelectricity and there isn't very much current there.

+ivan grompone The inside of the cylinder where the electrodes are is already completely covered so there's no more place to put aluminum foil. Removing some of the foil would make it work less well. As for adding more electrodes, there's probably some sweet spot in terms of how many is best. More than that would probably just contribute to losses. But I don't have any way other than trial and error for figuring out how many. As for a Tesla antenna, I'm not familiar with it. Tesla's Wardenclyffe tower was a transmitter as far as I know. Crystal radios are radios what use the incoming radio waves to power themselves but the power is very low. Re patents, I have a book with all of Tesla's patents but I haven't read them all.

I tried putting it on a small four wheeled vehicle with a pulley system to convert to a lower speed, gearing it down essentially, for the wheels but I couldn't get enough torque.

It's called Bicycle and it's by Kevin MacLeod (incompetech.com).

Sweet! Thanks - now I've learned two very cool things today.

Probably not. It works by producing ions in the gap between the blade and the surface of the cylinder and molecules (e.g. air molecules) are needed for that.

Muneer Arif No. An AC stabilizer puts out AC whereas this need DC. Also, I suspect the DC voltage required is in the low thousands of volts.

No, unfortunately not. Electrostatic motors tend to not work as generators when turned like that, unlike electromagnetic motors.

role od innej aluminium foil? Will it work without it?

Thanks, I've seen his. His number look very good.

hi li Very thin bare wires would also work. The advantage of the blades is that you can angle them, which gives an initial direction for the motor to move. If you use wires or if you make the blades point straight at the motor then the initial direction is left up to chance.The foil isn't necessary to get it working, but gives you enhanced performance due to that electrostatic induction. The foil results in a stronger electric field between the blade and the foil than you'd have if it was just between the blade and the atoms of the plastic. That gives more corona and more repulsion.I've yet to make a video explaining how it works but I do have an explanation on my website here rimstar.org/science_electronics_projects/corona_motor_electrostatic_atmospheric_motor.htm

interesting, so the charge flies directly out of the blades, like a tangent to the surface of the jar? I always thought electrostatic charge acted radially. Interesting.

OOOH cool cool cool. great description page. I didn't realize the blades alternated that way. That makes so much more sense now. The charge gets stuck on the insulator as it tries to move to the foil and that attractive force between the charge and the positive blade pulls them together. perfect. Thanks so much for your reply. I've never seen one of these before. I've only heard of them once. really awesome.

I see... the angle of the blades puts the charge closer to the next positive blade than the preceding blade, so even if the electrostatic charge travels radially into the foil, the geometry still gives it a bias in one direction. fantastic! will have to save my money so I can try to make one of these some day.

Yes, you could connect it to a motor to generate electricity.

@@RimstarOrg at what scale and Is it possible to use Corona or atmo motors in Fans like ceiling fan or room air coolers with dc supply. As they are light weight and obtain high speed. Less weight means do they consume less electricity as compared to other dc or bldc motors like they are heavier then this. please answer both?

I suspect these (electrostatic motors) are less efficient than electromagnet motors (the kind you find everywhere) despite the weight difference. The conduction of ions between the blades and the cylinders allows for a lot of loss.

As you can probably guess from 1:40 in the video, I designed and drew it all out on the piece of wood, using the diameter of the cylinder as a starting point (i.e. I made it big enough so that the blades would be close to the cylinder while still being adjustable). So if your cylinder is a different diameter then you'll have to come up with dimensions which work for it. If you still need dimensions then let me know and I'll put something on my website. But I'm super busy so it may take a while.

Muneer Arif I don't know how much power it needs, but it is very little. It needs high voltage but very low current. Pretty much any high voltage DC source should work.

The air gets ionized a lot go an ion meter will help measure that.

Yes, you can connect high voltage capacitors directly to it.

I'm not sure if it would. Pulses might be too brief for it. I can't say without trying and I don't have any high voltage pulsed DC source.

Muneer Arif If you mean the plastic that the blades are attached to, I cut them from plastic sheets that I bought at a hobby store. But anything that's not electrically conductive (don't use metal) will work e.g. plastic, wood. Look around your place or in stores for anything you can use as is or you can cut pieces from e.g. popsicle sticks, straws, plastic containers, ... Maybe even corrugated cardboard from boxes will be rigid enough. Keep an open mind when looking. The plastic I used for the circuit boards in my latest video about wireless transmission of electricity was cut from plastic that was a container for an appliance I took apart.

Muneer Arif In the comments to my video kzfaq.info/get/bejne/nMqmhal2m56UpWQ.html one person said he uses "Carb cleaner" and another said "you can clean the grease out with brake cleaner. I would do it outside though as the stuff is stinky. You don't need to rinse after using brake cleaner."
