Hello everyone,
For my physics class, I want to build an AC motor with styrofoam, magnets, screws and magnet wire.
So far, I have built a cylinder of about 2.5" of radius and 1" in height with eight magnets (strengh 6/10) around it. Each magnet is glued on the side of the cylinder alternatively north, south, north, ... .
This cylinder is crossed by a wooden stick that allows it to rotate.
I also built a ring of styrofoam that goes around the cylinder. Across each magnet on the outer ring, I have eight screws with wire magnet wrapped around them (150 turns each).
Should I wrap the bolts alternatively counterclockwise and clockwise or does that matter?
Also, I heard that I need to have AC current going through it (I have tried with a 9V battery in the past which didn't make the system rotate). How can I get an AC current going through it?
I also tried to light a small LED light by connecting the magnet wires around one bolt to the led light and forcing the center wheel to turn. The light did NOT turn on. How can I make it light up? If I connect all the coils in series, would that work?
My teacher said that there was a way to make a commutator with aluminum wrapped around a stick and cut on one side. How would that work?
Please, let me know if you have any idea to make this project work.
I would greatly appreciate it!
Thank you.
