Very clear explanation of what creates the rotation - just excellent. I study electrostatic turbines, aka electrostatic motors. If a very light load, or no load, is placed on the rotating part, and you can still find a practical use for the rotation, it is a reliable way to get rotation without the need of a motor and controller - all that's required is the charge separation provided by the DC supply and the ground. Benjamin Franklin created an electrostatic motor - if you do a web search on "Ben Franklin electrostatic motor" there are links to it. He built his electrostatic turbine in the year 1750. Thank you for the very helpful explanation for laypeople on why the rotation occurs.

In the video the cup spins clockwise, is that more likely than counterclockwise? Also why doesn't the cup just tilt away from the wire (it has some sort of torque instead, why is this?). Where does the angular force come from?
@electricandmagneticfields2314
@electricandmagneticfields2314 9 жыл бұрын
If it was completely symmetrical it would be equally likely to start spinning clockwise or counter clockwise. There is probably some asymmetry, my wire not pointing directly at the cup, that gives it some preferential direction to spin. This is also why it doesn't just tilt. Also imagine pushing the cup with some pointed object. It would be hard to balance it in a tilted position without it slipping to one side or the other and rotating.

I am a student at Queen's University and I have a physics project that is based on this idea. Is there any way of making this a lot stronger? What would I have to do to increase the angular velocity and increase the torque applied to the cup? Maybe another source other than a van de graaff? I would like to know the math that would allow me to calculate the exact current or voltage that would allow me to spin not only a light cup like in this video, but something on the scale of 2-3lbs spinning at the same speed as you have with the cup. I have already made this apparatus, it spins quite well, I have added a base to the cup with a hole in the middle to stop any swaying. I just want to know how to tackle the problem to make it stronger.
@electricandmagneticfields2314
@electricandmagneticfields2314 9 жыл бұрын
A higher voltage, but you will probably be limited to the voltage you can go up to by dielectric breakdown of the air. How about instead of one wire on each side multiple wires? I like your idea of the base to stop the swaying.
@neutronenstern.
@neutronenstern. Жыл бұрын
Might be very very late, but the force is due to electric fields. Thus increasing the area will increase the force. So in addition to the wire, which will get charges to the plates, you can use a bigger area of aluminium foil right next to it. It will act as a bigger stator, than the wire itselve is. You will have to connect it to the sane voltage as the wire is comnected to, for it to work. To make it spin faster while maintaning high tourque you might have to get it closer to the rotor. Also you can of course increase the voltage.

When operating just the van de graaff generator, which I am using to power this electrostatic motor, I have detected the smell of ozone. This electrostatic motor would work in a vacuum. You would have to get a large enough electric field to get emission of electrons from the Al foil facing the positive electrode. In this demonstration I am already getting a large enough electric field to get electron emission from the grounded electrode because of its high curvature.

Electrostatic motors were the first motors developed in the 1700s. They are limited in how much power they provide and they require high voltages. Motors with coils based on magnetic attraction and repulsion became the convention. There has been renewed interest in electrostatic motors for microelectromechanical systems (MEMS). These are systems built using integrated circuit processing techniques in silicon. You cannot built a motor with windings in a MEMS, but you can build electrostatic motors. There are some videos at this web site showing working MEMS motors, www.sandia.gov/mstc/mems_info/movie_gallery.html

So the Electrostatika car is a combination of an electrostatic motor and an electrostatic generator. Instead drain current in the ground (ions) in the drain neutralization Leyden jar. It is generated by friction electrostatic current (hand-on) then this current drives the electrostatic motor and the current after the neutralization of ions accumulates in a leyda bottle. If conductive brushes are disposed obliquely, they produce an amplified rotation in electrostatic motors. The 1000-point question is how do we remove (use) the current from the leyda bottle ?!

@electricandmagneticfields2314
@electricandmagneticfields2314 10 жыл бұрын
Patrick Sarmiento The only requirement on the gaps is to electrically isolate the strips of Al foil. So the width of the gap should not be critical. Also the number of strips is not critical. I think it will work with as little as two strips, although a larger number of strips will probably result in more efficient charging and un-charging of the strips of Al and better rotation.

+amogh bindal It would not turn. The part of the conductor opposite the positively charged electrode could not become positively charged. So there would be no repulsive force between the electrode and the conductor on the cup, which is what makes the cup rotate. Any positive charge resulting on the conductor on the cup caused by the positive electrode could flow away leaving the conductor on the cup opposite the positive electrode always negatively charged. So there would be an attraction between the positive electrode and the conductor on the cup. Just to be sure I tried the experiment with one piece of aluminum all around the cup and it would not rotate.

You are correct that there is charge transfer to set up the repulsion. In all motors referred to as Electrostatic motors there is a continuous transfer of charge from the voltage source to ground through the motor. Another example is Franklin’s bells kzbin.info/www/bejne/iJKumWqQpLGXZq8
