Picture of How to Make a Simple Motor
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

Picture of 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

 












Step 2: Creating the Copper Wire Coil

  1. Cut a length of copper wire (between 2 and 3ft) using a pair of wire cutters.
  2. Use a AA Battery as a winding template; begin winding the Copper Wire around the AA Battery (Make sure to leave about two inches of wire trailing off one end of the coil).
  3. Continue winding the Copper Wire around the AA Battery; make sure that you wind a nice tight coil. 
  4. Leave a length of wire (two inches) trailing from your coil after winding the Copper Wire around the AA Battery 15 times.
  5. Wrap the trailing ends of wire around your coil two or three times.  This will hold the coil in place (its important to wrap the ends directly across from each other; balance is key in creating a good motor)

Step 3: Sanding the Ends

  1. The two ends that are trailing off the completed coil need to have the enamel sanded off of the Copper Wire (this is extremely important because the more enamel you remove the better electrical connection you are able to make between the AA Battery and the Motor).
  2. (This step is even more important than the first) Start by sanding only ONE SIDE of the trailing ends of Copper Wire. (Only ONE SIDE)
  3.  The other trailing end of Copper Wire needs to have all of the enamel completely sanded off.  (Remember, the more wire you expose the better the connection)

I like the design I tried to make my own but I made a coil that was too small
is a 1/2" size Neodymium Magnet OK

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)

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 "J" pieces of bare solid copper wire and soldered them to the ends of a common "C" battery. The armature rested in the "J" 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.

here's a link to Museum's Blog for the MakeShop, it has video of the motor in action.

Very cool! Good pictures, although having the wood block on the wooden workbench makes it a bit hard to see clearly.
