Snail13579 Posted June 7, 2008 Share Posted June 7, 2008 how do i make a dc motor? i know the materials, but im not really sure why its not spinning. I made it so it has a copper wired ring in the center with magnet at the bottom and a battery powering it. Is it the wires that led from the battery to the copper wire the problem or what?:confused: Link to comment Share on other sites More sharing options...
ydoaPs Posted June 7, 2008 Share Posted June 7, 2008 Are you using a commutator? Are you using just the one magnet? Link to comment Share on other sites More sharing options...

ydoaPs Posted June 7, 2008 Share Posted June 7, 2008 How about the commutator? That's an important bit. Link to comment Share on other sites More sharing options...

doG Posted June 7, 2008 Share Posted June 7, 2008 Here's a simple motor that may help, http://scitoys.com/scitoys/scitoys/electro/electro.html About halfway down the page you'll see a part about stripping the magnet wire on one side. That's the commutator. HTH Link to comment Share on other sites More sharing options...
YT2095 Posted June 7, 2008 Share Posted June 7, 2008 don`t over-complicate matters, here`s a simple DC motor I made up in about 30 seconds: the magnet on the nail is actually spinning, but you can`t really see that in the pic. here are the parts needed: 1 battery, a nail, a Magnet on the end of the nail, and a bit of wire. see, Nothing complicated at all Link to comment Share on other sites More sharing options...
Snail13579 Posted June 7, 2008 Author Share Posted June 7, 2008 i wanted to make one that does work, and that has a ring in the center, but im still not really sure about the wire part Link to comment Share on other sites More sharing options...
YT2095 Posted June 8, 2008 Share Posted June 8, 2008 post a Picture of what you have so far then, it`ll be easier to explain the error and corrections needed from that. Link to comment Share on other sites More sharing options...

Snail13579 Posted June 8, 2008 Author Share Posted June 8, 2008 right now, im just using normal copper wire. im sure that the problem is at the insulation and/or the "magnet wire" which i have no idea what that is. the rest i got it covered. im building a beakman's dc motor btw Link to comment Share on other sites More sharing options...

Magnet wire as a very thin layer of insulation so that it can be wound in tight coils where the windings do not short circuit with each other. Some simply has a thin varnish on the wire that you can scrape off with a blade of some sort. In a Beakman's motor you scrape it off on one side to form the commutator.

Snail13579 Posted June 8, 2008 Author Share Posted June 8, 2008 (edited) what kind of wires at home can be used as a magnet wire? edit: wouldnt the magnet wire be attracted to the magnet? it should be normal copper wire with insulation IMO Edited June 9, 2008 by Snail13579 Link to comment Share on other sites More sharing options...
doG Posted June 9, 2008 Share Posted June 9, 2008 None that will work in a Beakman's motor. Since the wire acts as an axle of sorts in the commutator it needs to be fairly round even after the insulation is scraped off on one side. Link to comment Share on other sites More sharing options...
Snail13579 Posted June 9, 2008 Author Share Posted June 9, 2008 so what kind of wire do i need? be specific with examples please Link to comment Share on other sites More sharing options...

You might try this in the future if you need a quicker answer.... http://www.google.com/search?q=magnet+wire Link to comment Share on other sites More sharing options...
swansont Posted June 23, 2008 Share Posted June 23, 2008 Really simple motor I stuck in a blog post today. Wire, battery, appropriate magnet, and one hand fewer required than YT's example. http://blogs.scienceforums.net/swansont/archives/484 I built one of these this afternoon. Quick 'n dirty. Had to get a magnet at the hardware store, but the actual construction was about ten minutes. Updated my post, so the video is there. Link to comment Share on other sites More sharing options...
