why is a video 10 years ago so good quality

Amazing experiment, excellent thinking. More rotations in the copper coil, the stronger the magnetic flux, therefore higher torque.

Thanks man, i can build my own car now.

project videoes are a fantastic idea. well done. please keep 'em coming!

In a comutator based d.c. motor the two contacts for the rotor coil(solenoid), or the brushes, will be 180° apart. In a pulse driven motor the said contacts can be on the same side . . ?

Great video!!

You Are Genius !

Wow I remember my young self watching this amazing video

Awesome vid

Great Video!

I haven't worked on it, but I have thought about it. You know, there are theories that a space-time warp drive is possible. The only problem is, it requires the energy mass of Jupiter to work. So ... but because the electromagnetic field is embedded into the fabric of space time, I don't see why we couldn't exploit it in some way for propulsion through space. I think we will need to unify all the fields before we have enough understanding to do so.

where did you buy that electrical wire attached to them batteries? please tell

Very good video thank you so much also i will try this you got a new sub

Using 6 Volts(from four AAA cells) seems a bit much!! I think you could get equal results from 1.5 Volts from a C cell

It seems to be 12V instead

thx for your experments>

5:42 Five loops does not mean five poles. The motor in a hairdryer has many loops/turns of wire within it! The motor in an AC powered hairdryer has no permanent magnets!

It doesn't work and it's painful. Should the distance between the two magnets be equal to their distance from the center? Also, how many volts do you use in the battery?

Can you give a list of the materials?

this is an awesome video you explained everything perfectly so now i subscribed

Am making mine thanx...i would like to book online class ..

Why not make a windmill to spin magnets in the center with a coil surrounding the spinning magnets?

Great Video!!! but is this a motor with Commutator or the one with out commutator?

Blooming Talentz this doesn't use a commutator. he only scrapes half of the wire so that way he doesn't need to reverse the current to allow it to spin but by doing so he sacrifices half of the potential power

interesting video

Hi, I can see you didn't use any commutators so its rotation should bounce between clockwise and counterclockwise. Is your motor doing so?

Thanks alot

Why do you only scrape one side of the wire?

Can you please explain how it works?

is this a dc motor?

why do we have to scrape off the ends??

Why does the Copper wire need to be symmetrical? Or follow in the same path as the layers below it.

if it is longer in one part than the other it will get hotter over time, causing bad things to occur

So is this a new branch of educational video from Khanacademy????

Now I get it, the copper wire turn because of the attraction and repulsion; and because it is placed in a torque, it will repeat the cycle again.

how do i make a more powerfull motor, like to be able to change the position of 80kg weight, 1/10 of a car

lucas falenski Well so far i know you need a very stronger energy source. but i am not sure how to use the source tho.

Thanks

So how'd that work out for you?

Why couldn't someone make something where electromagnetic waves are emitted and directed through a special coil in order to create force in one direction rather than rotational motion as in this example. So it would be something that could give propulsion in empty space. It's not a perpetual motion device, because it would use up energy to create the EM waves. I suppose I'll have to just make one and see why it can't be done. If I succeed though, I am sure our US military will want to use it.

Hi, can you please give me a detailed list of the materials? Because i was trying to do the experiment but it doesn't work. So Maybe you could help me with this! Btw Congrats for the video is great!

The video has serious safety issues. Don't do it the way he did because there is risk of serious burns from touching the rotor winding. Running the motor for extended periods of time can also be a fire risk. To do it properly, you need hundreds of turns in the rotor to reduce the current to a level that won't cause the wire to heat up. But you'll also need to wind the wire around something iron, like a nail, to increase the strength of the magnetic field.

You could try putting a stack of washers that fit perfectly inside the coil. Because of the added weight, you might need to MacGyver some sort of support so that it doesn't bend the wire ends.

Why does he scrape the coating off?

@jackbalitok3910

6 жыл бұрын

The lacquer coating is meant to protect the copper wire but it also act as an insulator, scraping the coating off means removing that resistance which lessens the conductivity of the wire so that electrons could move more smoothly.

Quite frankly, the instructions in this video are dangerous. The rotor _will_ get hot enough to cause burns. If left on for an extended period of time, it may even be a fire hazard. First of all, you're using 3 inches of wire to build the rotor winding. That looks like 32 AWG wire, so you're putting over 140 A of current through it with the 6 V battery. You NEED to use a lot more length, at least 20 feet, or else it's going to melt. The batteries are also not going to last more than a few minutes. Obviously you did it this way to generate a strong enough magnetic field to turn the rotor. But that's because you used an air core! Use an iron core -- even a nail would be significantly better! That would reduce the required current by a factor of 5000. To get the correct resistance for that current, your rotor needs to have hundreds of turns. And number of poles is NOT the number of loops. Number of poles in a motor refers to the number of _magnetic_ poles. You have two poles. It's impossible to have a working motor with just one pole.
