No no no, if you reverse the polarity the motor will still turn in the same direction! That only depends on the geometry thus that two wires besides that cans.
Nice video as always Mr Ludic! You raise a number of questions: Will the motor operate w/o the wires? How does it's operation depend on the distance of the wires from the CD? Can't you get the disk to rotate CW or CCW regardless of the polarity of the cans? Finally if the Cu disks are charged where did the charge come from? Surely the disk are electrically polarized not charged.
Inverting the polarity won't change the direction of rotation. Why whould it? The direction is given by the wires that are stuck to the cans. You would need to flip them to the other side of the can to invert the direction.
I love your videos. I wish I had you for a teacher when I was in school. I own my own electronics company today and I still love watching your videos. They're really good. Thanks for posting them!
You can also small led light work with small amount of static electricity if you have the polarity right. I tried it and it worked despite it flashes a lot and does not stay steady.
So that's how you remove the coating from a CD. High voltage discharge! lol. Anyway, nice video and and a good design. But your explanation of the motor should include how the copper disks alternately become charged and discharged as they rotate.
His explanation ánd built is only half correct. The direction of rotation depends only on that two wires besides the cans and nót on the polarity; ánd that area of metal around the dvd, thats the layer (only half gets erased by the hv-sparks from the plastic) without gaps is a short circuit in this motors built, decreasing the working thus the efficiency badly. The idea is nice but the built ánd the explaination, both are only half correct, Thus wrong. Sorry
Nice video and tutorial. How do you know which side of the HV output is positive. I have the same HV power supply but I did not know it was DC I thought it was AC output.
use a neon lamp. neon indicator lamps have two probes inside the lamp out of which the -ve probe (or cathode) glows when a high voltage is applied (about 60v or more). You can get a neon lamp inside line testers or mosquito repellent (All out, only........Good night uses led) When AC is applied, both of the probes will appear to glow at the same time Always use a resistor of appropriate value in series with a neon lamp, because neon lamp being a discharge lamp may conduct huge amounts of current through it and get destroyed.
Anindya Mitra in fact I already blowed one connecting to mains without current limiter :-). Big surprise but good to learn because this experience is unforgettable :-)
Anindya Mitra oops it looks like I was missing something. You said the glowing side is the negative ? I was under the impression the glowing was on the positive HV side

Copper disc close to a positive soda can would have electrons attracted to the can and one side would be negative and the other side of the disk would be positive that is the side facing the positive soda can would be negative and and the portion of the disk that away from the positive can would be positive. Note that I'm talking about a single copper disk only. So your explanation is not correct. Plz explain it correctly. To rotate it you have to initially charge the disks
It doesn’t work with Pepsi...
Too bad, try with Dr. Pepper
Nice video, What was the voltage source?
Nice video

Next time use white color of table

So Good👍
Franklin motor has been known for a long time, but there is no practical one.
Please practicalize with your knowledge.

Why aren't more motors made like this ?
saudações a todos. que motor incrível!!! nós humanos somos criativos mesmo. parabéns por nos mostrar este engenho maravilhoso. sucesso.
Thank you for not calling aluminium foil "tin foil".

this is how to erase CD permanently.

@@anindyamitra5091 you can do with sandpaper
You can name it as Ludic Motor
But there is no use practically
Cool

Anindya Mitra thank you simple good idea. I know neons and forgot they go bright only on one side if dc and both sides of AC :-)
Anindya Mitra in fact I already blowed one connecting to mains without current limiter :-). Big surprise but good to learn because this experience is unforgettable :-)
Anindya Mitra oops it looks like I was missing something. You said the glowing side is the negative ? I was under the impression the glowing was on the positive HV side
Sir we can use aluminium strips ??
Yes
Great video! Thank you
Dear Mr Ludic: Can you do a video on an electrostatic generator? For example a Wimshurst machine?
His explanation ánd built is only half correct. The direction of rotation depends only on that two wires besides the cans and nót on the polarity; ánd that area of metal around the dvd, thats the layer (only half gets erased by the hv-sparks from the plastic) without gaps is a short circuit in this motors built, decreasing the working thus the efficiency badly.

Who invented the ‘electrostatic motor ‘ ?
And is electrostatic attraction a ‘magnetic feild’ ?
Great video thanks for sharing
Should have placed a high-speed ceramic bearing in the large opening of the tube to keep the wobble.
Very cool thx ...important...
very interesting
let me know what happens if we use permanent magnetics to make it spin
Hi
Hi
Just got notification
Like.......
💥
how much of voltage used for this??
High (in his terms: yes)
IS there still Coke in those cans ??
Yes
