Here is a fun way to explore the inner workings of a simple motor.  This is a great project for use in the classroom or at home.  Making your own Motor is an excellent introduction into the world of technology. 

Step 1: Materials and Tools You Will Need to Create a Simple Motor

  • Copper Wire
  • Paper Clips
  • Wood (3" 1X2)
  • Neodymium Magnet
  • Battery (AA)
  • Insulated Wire
  • Sand Paper
  • Staple Gun and Staples
  • Needle Nose Pliers
  • Wire Strippers
  • Wire Cutters
  • Hot Glue Gun and Glue Sticks


<p>dose it have to be wood</p>
<p>nice project</p>
<p>Hey! I had a question. If the copper wire is insulated, which it must be for you to have to sand it, how does the current pass from one end of the coil to the other?</p><p>--------x()x--------</p><p>In the points marked 'x', the coil is connected to two pieces of copper wire, but since it is insulated, current should not pass, right?</p>
<p>Actually the wire is made of copper just coated with an insulating material (or dielectric) typically polyimide I think (just a polymer/plastic). The current passes through the copper wire, but if you fold it on itself so that it's touching it doesn't short circuit (current passage through the touching junction instead of around all the loops of the wire.) Insulated wires are useful in making solenoids too where short circuits are really bad.</p>
<p>Hi! Thanks for the explanation. I didn't understand why we should sand only one side of the cable end. I don't get why and how we should do that. I sand one side but the other must not have insulation? So I need to sand both sides?</p>
<p>A trick you can do if you sanded both sides is rub a candle on one side, or use some nail polish.</p>
<p>Ok, you must sand 1/2 the circumference of BOTH sides of the wire ends.. let me elaborate why. When you hook up the battery to the wire coil, the electric current flowing through the coil gains a magnetic field. The permanent magnet inside the motor also has a magnetic field and these two magnetic field have an equal and opposite effect on one another; meaning that there is no stability in the reliability of the the coil spinning in one direction. When you insulate only 1/2 of the wire connectors you are allowing the coil to spin in one direction as the magnetic fields lose communication with each other every time the coil rotates around the insulated half. Hope this helps you!</p>
It is confusing. For one of the sides you need to sand half of the enamel off. Imagine that the wire has a top and a bottom. You only want to sand the bottom side and not the top. The bottom will become shiny and the top will remain red.<br><br>I hope this helps.<br><br>
<p>Is there anyway to make this motor go faster, to about 5000-8000 rpm?</p>
I've clocked over 20,000 RPM it by making motors that rotate on the vertical axis. As the Author mentioned, higher rpm horizontal-axis motors need a sturdy support system...or parts will fly! <br><br>I'm assuming this instructable was designed mainly to provide a very clear and consice introduction to the relationship between electrical current flowing through a wire and inducing a magnetic field (electromagnetism), not to mention the Author's account is for a Children's Museum so the motor probably has to be relatively &quot;safe&quot; :) I remember making my first motor exactly like this about 20 years ago when I was only 4 y/o!<br><br>Anyways, If you are still interested in building<br> high-rpm or high-torque motors, send me a message or reply here, and I can link you some great resources to get you going!
<p>hey man!</p><p>I was interested on how you gothink such high result. It would be great Ifor you could send me a link for you resources </p>
<p>i want to make a motor of 20,000 rpm....can u please help me</p>
<p>when it comes to gyroscopic motors , it really takes a lot of effort to construct a multi-motor rotatory circuit with arduinos and tranducers . At the age of 10, I constructed a drone with a quad-scoped motor board for extra propellance and power . It won the 2012's national military science fair:)</p>
<p>hello hheidermann</p><p>I am very interested in how you got up to 20 k rpm</p><p>if you could send info or link would be greatly appreciated</p>
<p>Without knowing what the average speed is for this project, my assumption is that 5,000-8,000 rpm would not be feasible since I think it would simply shake itself apart! It's not a very sturdy construction, after all. You could experiment with a few things to try to get the speed you wanted, including adding more battery power, using a stronger magnet to create a larger field, and adjusting the number of coils (remember: each extra loop of wire also adds more weight that has to move!)<br><br>Let us know if you discover some good tips to make it go faster, or work better!</p>
thank you <br>i will visit your museum
What should be minimum voltage that works for it?can i use my 6 volt rechargable battery for it.?what should be minimum strength of magnet...?
I like the design I tried to make my own but I made a coil that was too small
is a 1/2&quot; size Neodymium Magnet OK<br><br>
I made one about twice that size, and put 40 amps at 8.4 volts through it. Very impressive sparks from the contacts and smoke. Can only do it for a few seconds at a time because it gets so hot

I made one of these a few years ago, I used plastic coated wire, I stripped both ends, then on one of the wires I put a thin sliver of tape that covered half of the wire (at the time I didn't have any enameled wire)<br><br>I would recommend not gluing the magnet until you test it, mine will only work if the magnet is in the right direction, even if i reverse the power.
I have seen these called a Beekman's Motor or a Ten Minute Motor. I once made one for demonstration. I made two &quot;J&quot; pieces of bare solid copper wire and soldered them to the ends of a common &quot;C&quot; battery. The armature rested in the &quot;J&quot; hooks. I had a doughnut-shaped ceramic magnet from Radio Shack that gripped the steel case of the battery just above the armature. I gave it a gentle tap and it was off and running. I simply held the battery without any wooden bases.
noted, I will take that into consideration on the next instructable. thanks.<br><br>here's a link to Museum's Blog for the MakeShop, it has video of the motor in action.<br><br>http://makeshoppgh.wordpress.com/2011/08/11/make-your-own-motor-or-coping-with-variables/<br><br>check it out!
Very cool! Good pictures, although having the wood block on the wooden workbench makes it a bit hard to see clearly.
