The use of this instructable will enable anybody to create a small motor. By using some basic materials, you can construct a motor that spins. It uses the basic principles of a motor, the coil forms an electromagnet that repels against a permanent magnet, which in turn breaks the circuit and allows the motor to spin.
Step 1: Gather Materials
In Order to create this small motor you will need:
One D-cell Battery
Two medium paperclips
Approximately two feet of magnet wire (26 gauge)
A small patch of sandpaper (We used 80 grit)
Two rubber bands
One Small Magnet
Step 2: Create the Coil
-Begin by holding the magnet wire against the Battery, keeping around 1-2 inches to one side as a tail. Wrap the longer side around the battery in tight coils against the battery. Continue wrapping until there is approximately 1-2 inches left.
-Carefully slip the coils off the side of the battery, pinching them so they remain coiled. Begin wrapping around the coil with one of the tails to keep it tightly formed. Do this with the other tail as well, when you are finished it should be symmetrical, with the two wires coming off opposite to each other.
-Sand one of the tails of the coil so half of the enamel is still showing while the other half is copper, On the other side sand all around the tail the whole way around so copper is showing around the whole tail all the way to the coils. (One side should be completely exposed copper, the other should be copper on top and paint on the bottom)
ProTip:To sand the 1/2 copper tail place the wire along your finger. Using the sand paper, sand the exposed side of this wire so the enamel comes off of it
Step 3: Create Paperclip Stands
Unbend the paperclip so the small bend and large bend are opposite each other. Bend the smaller sides end up to form a hook.
ProTip: When bending the paperclip bend it to the side so it doesn't break, the picture above shows the various stages of bending to make a final stand paperclip.
Step 4: Making the Stand
Wrap a rubber-band around the battery, double wrapping it if necessary, Slip the bent paperclips, hook side up into the rubber band between the band and the charged ends of the battery. Place the magnet, on the battery, between these two stands.
ProTip: Use a second rubber-band around the battery to help the battery to stand on its own. The friction of the band against a surface is usually enough to keep the system upright.
Step 5: Starting the Motor
Place the coil of wire on the stands so each tail is on the stand.
ProTip:Give the coil a light tap to get it going, and then allow it to spin on its own and enjoy your awesome simple motor!
Step 6: Trouble Shooting
If your Motor doesn't spin try some of these:
-Place the tails on the opposite stands
-Make sure the coil is symmetrical
-Try a fresh battery
-Make sure you sanded the necessary side(s) of the tails all the way to the coil
Step 7: Conclusion
Through the successful completion of this project you have demonstrated the basic principles of a motor. Your understanding of these concepts should be improved as you have worked with the physical parts that are the most basic parts of a motor. You should have developed a greater appreciation for the science that goes into engineering a motor, and the amount of thought and effort that goes into making it work effectively.
