How To Build A Simple Motor(wikihow)
This article will show you how to make an essential electric engine, incredible for straightforward test purposes or for a science venture. You'll be utilizing the electrical vitality from a battery to create mechanical vitality that turns a loop. This is an extremely streamlined rendition of engines found in family unit apparatuses, force instruments, PC plate drives, and a significant number of alternate gadgets that make your life less demanding.
Make the magnetic coil.
Take a thin, coated magnet wire or copper wire, and wrap it 10 times around the edge of the paper tube. Leave a few inches of loose wire at the start and end of the coil.
Carefully take the coil off the tube. Wrap the ends of the wire around the coil at opposite points of the circle. Add some tape to help keep the coil together if needed. Once you have the coil secure and balanced, you can cut off excess wire leaving only an inch on either side.
Start making the base. Poke four holes in the plastic cup using the thumbtack. Place one hole 1⁄2 inch (1.3 cm) from the top, and another 1⁄2 inch (1.3 cm) from the bottom, then do the same on the opposite side. If you don't have a plastic cup, a styrofoam or paper cup will work too.
Make the leads to the battery. Cut two pieces of stiff wire at a three times the height of the cup and thread them through the holes in the cup.
Position the cup upside down. Place one magnet on the outside of the closed end of the cup. On the inside, place another magnet, or more if necessary, to hold the first magnet in place.
Sand the wires. Sand the ends of the wires at the base of the cup and set them up to connect them to your battery.
Adjusting the wires that will hold the coil. Stand the coil up on the magnet and match the height of the coil to the support wires. Bend one of the wires connected to the base forward, and the other backwards at the height of the coil.
Make a perch. Keep bending the wires to create a perch for the coil, so that the coil is held up with as little space as possible between the coil and the magnet.
Sand the support wires. Take the coil and sand all the coating off one of the support wires. On the other wire, only sand off half of the coating so that the coating will start to touch the support when the coil is closest to the magnet. If you want to adjust the sanding, you can just apply a new coating with a permanent marker (applying the coating with a permanent marker is very important as it breaks the magnet field and keeps the coil spinning).
Connect the battery and test your motor. Secure the wire to the battery using tape, making sure that either end of the wire is touching the positive and negative ends of the battery. Some minor adjustments may be needed.
