What stupid things I've done to make the motor

I have studied electric before when I was in middle school. I was smug that I think I can handle it without reading those 2 pages instruction in English. So I didn't wrap the 14AWG wire on the bottom of the string.

I thought the wire was used to bulb up the power of the motor. But actually it can create a magnetic field when the electricity goes through it. Because battery has +and - part that the electricity goes from + to-. And magnetic systems have N and S. When they combine, it can create a large magnetic field.

so I have to remove the neels and wrap that hard wire on them QAQ which is a really exhausted job.

How hard to build a motor!!!

I would say it's not hard to build a motor if I followed the instructure at first and go through it. But I didn't, it caused so much trouble.

The hardest part is to get everything. I went to home depo and tried to find the iron. They were not too big or too small to use. Because I was told to find some 80 cent iron, I got nothing. I found the 14AWG single strip, wire but I found it 20 dollars expensive than what I had been told.  I found lots of strings but I could not be sure about how it will be so I didn't buy it either. So I only bought a lamp wire and battery in there.

When I finally find everything and started to build my motor. I was struggled by stapling two string cross together.  My host dad gave me some duck tape and it worked well.

When I wrapped the magnet wire on it. I tried my best to make it close to each other and tight. But I found out it was too tight that the other side was getting wider. So I have to redo it. I put a little piece of metal at the end of the side I was wrapping. so it won't get smaller.

When I finished wrapping hundreds times of wires, and finish building it, i started to test it.

It started to shake and connect to the side. I tried to find the problem. I realized it might be that I over cross the side with the magnet wire to staple the cross. When I changed that, it started turning slowly!!! When I fixed the brushes a little bit, it started to spin really fast.

Because I found out how did the motor in the classroom can be wrapped so smoothly, I think I did a pretty good job on that.

It's hard to build but I had lots of fun playing with it when it start to spin.

General Motor

    We can see all kinds of motors in our daily life. The most common kind is  in cars. The motors in car are generated by fossil fuel. It turned fossil energy to thermal energy  and then into kinetic energy.

But this is not the motor we are going to build. This motor was invented by Thomas Edison. By using electronic current to create magnetic field and by turning the + and - side to lead the motor move. 

The first time i saw a motor was on a model car when i was in primary school. And it used the Edison motor to generate its power. 

I always saw boys playing it and show off their new motors. And I also saw them messing up with it by getting rid of the shell and using the part inside as a spinning top.
