does anyone know how to make a little motor for a school project?

Hard to explain here. Motors are simple actually, so, I know you can do this. Be nice if you had someone to help. Go here; http://www.simplemotor.com/kits1-4.htm\nThis link I choose so you see one of the Kit Projects. On left menu click Home for the real place to start. I have not look and read much, but, I think it show many ways and may give you some instruction on doing this. At the Bottom of Home Page you find Kit # check them out. ;-p

I had to do this before, but I had to make mine out of candy. If you're allowed to do that, use candy. It's pretty easy. Just get some wire, twist them to the right shape, and use different kinds of candy on them. Once you have those up, then you'll need the wires that go across to connect them. I find that candies like twizzles and gummy worms work well. It shouldn't take that long to make. Good luck!

Cut out a cardboard circle, draw colors on that or glue the color wheel on it.\nPut a needle through the centre (as the axis) and use 2 forks to hold the needle.\n\nIf you need a lot of spin, tie a rope around the needle and pull

Check on E-bay, they have a few similiar vintage models you could compare "going" prices on. Also if it runs and you are close, i'll buy it. I need a motor for my fishing boat.

OK I'm cheating - I put this answer up a little while ago.\n\nA quick and dirty idea for a physics project would be one based on electromagnetism. Without knowing what grade you're targeting, a simple one that has a fair amount of pizzazz is to build a gauss rifle. Checkout http://sci-toys.com/scitoys/scitoys/magnets/gauss.html\n\nThe sci-toys site has some other pretty cool stuff that you might find useful as well.\n\nFor a more advanced example, you can make a small rail gun that applies similar principles but can have a much larger kick. Just do a search on "rail gun experiment".\n\nEnjoy!!

We make small display rotators if you check out our web site you can get an idea how we build them. You probably just need a slower gear motor. You can change the pulleys for different speeds but then you need to change the belt size. It is always easier to get a motor close to the final speed you want.\n I don't know what the cabinet looks like or what kind of space you have for the motor but it may help to see how we build them. www.semcomotion.com

Here are a couple of web sites that approach this in different ways. \n\nhttp://www.circletrack.com/techarticles/84199/\n\nhttp://www.diracdelta.co.uk/science/source/e/n/engine%20excitation%20mechanisms/source.html\n\nHope these help.

Read this article and the other links inside.\n\nhttp://en.wikipedia.org/wiki/Dc_motor

Actually what you want to build is an electric *motor*, not an electric *engine*.  By definition, an engine has a number of working parts that move sychronously, whereas a motor is a simple moving machine (my English teacher nailed me on this back in the 12th grade and I've never forgotten it).\n\nBut nevermind all that semantics stuff.  See the link below for some excellent how-to examples, depending on how powerful a motor you want to make.\n\nHave fun!

well, i cant really explain it, but you can use rubber band or a mousetrap to power the car. if u google "mousetrap car" or "rubber band powered car," you'll find diagrams and steps on how to make it.
