How to Make a Simple Motor
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.
How to make a simple electric guitar
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?--------x()x--------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?
A trick you can do if you sanded both sides is rub a candle on one side, or use some nail polish.
hey man!I was interested on how you gothink such high result. It would be great Ifor you could send me a link for you resources
i want to make a motor of 20,000 rpm....can u please help me
My grandson and I built a simple electric motor for his school science fair and he won
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:)
hello hheidermannI am very interested in how you got up to 20 k rpmif you could send info or link would be greatly appreciated
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! 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 "safe" :) I remember making my first motor exactly like this about 20 years ago when I was only 4 y/o!Anyways, If you are still interested in building 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!
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!)Let us know if you discover some good tips to make it go faster, or work better!
