Electromagnetic Motor Configurations

Overview

Objectives/Goals Electromagnetic motors specifically run on electricity and magnetism. When you put these together they may run very fast. My project#s main purpose is to test the different effects that different ways of wrapping wire around the rotor affects the speed of the motor. Methods/Materials If you look on you will see all the tests I have done to see the difference in the way you wrap the wire around the rotor. I tested five different ways of wrapping. Each of the wraps has different styles of wrapping. The different wraps were all unique. All of the settings that I used were exactly the same. I also used the same batteries every time. When I tested the batteries they were one volt less then when they were fresh. Results In the end I found some interesting results. I found that with more wraps and less gaps that the motor seems to run quite a bit faster. The runs with gaps were ok but the rotors with more wraps and fewer gaps were the best. Conclusions/Discussion The rotors with more wraps surprised me a lot. They ran much faster then I expected. I also found that there is a so-called point of safe return where too much weight makes the motor run much slower. When this happens, it was a good time to stop.
