@Tim Callinan PLEASE--any time you propose to teach a thing, explain (before giving the dimensions of wood, for example) what you're doing: Give a general overview of both what the project is intended to do, and what it is intended to teach. Show the finished object and point to the main components and what they do. Providing context for the various parts (this does x, that does y) is essential to good teaching. Then show the fabrication and assembly. A parts list will also help those watching visualize the project.
Hey tim! Love the video! The bolt you have with the nuts on it is called all-thread. The white pipe is pvc pipe, and the blue is called conduit, and the copper pieces are pipe brackets
Did you have to give it a push, or it starts by itself? Me and my brother use to make those when we were kids but we had to start them by hand; we used bicycle spoke for shaft, Ï transformer plate for rotor, old relay wires for winding, antenna tube for bushing, and commutator. I took great care building mine, I coiled the spirals by side without gaps 2 layers on each side of Ï plates. It would make me mad because my brother would coiled his just like you did, he wouldn't take the time to coil it beautifully, but his would turn faster then mine every time. One day I will make a replica and post it! Thanks guys, it brought me old memories! I will never forget the smell caused by the friction of brush and commutator after being ON for a while!!!
hey Mr Callinan, im confused about the direction of the current? if i follow the current with my right hand rule, placing my fingers in the direction of the magnetic field and my thumb in what i believe is the direction of the current which is looping around and around along the wire and i find that the force that the armature is supposed to move into itself (if that makes sense). Do you mind explaining where the direction of the current?
Nice motor sir........ Just a few questions...... 1. How much power magnets you used. From how much maximum distance each can deflect the compass needle??? 2. How much wire you used for making solenoid or say how much wraps??? 3. Will it work well when I created a potential difference of 9V??? Or upto 18 V using a dc battery???
well i didnt watch the whole thing, but already im shocked about how short time it takes you to build it and how efficient it is, so if i build it maybe a tiny bit more efficient and a lot bigger i maybe could get 1 hp out of this thing.....enough to move a small car, def making one thnx for explaining, just i want to ask you, how much hp does this produce? and also how much torque can it do?
If the wire is not insulated, how could you wrap it around on its self without it shot circuiting the coils and just taking the short cut through all the wires that are touching?
If you were to use a plastic pen as an armature, it wont create such a strong magnetic field around the copper wire, it will still work just not as much torque

Would have been great if you had the supplies/materials listed in the description box.
Very good video :) helped with my own design! Thanks for putting the time in.

Nice little weekend project :)
It was either the titanic movie or this video, glad I picked this video. 110/109% educational

great video
Damn, this video was incredibly useful, I have to make a motor for a physics project and this was a very big help, thanks
grrnib
same!

How did it go?
What a great video!
Olá amigo!
Parabéns pelo excelente vídeo, gostei do motor caseiro.
Excellent video. Thanks!
This video was great but it would really be nice of you could post a simple supply list I spent 1 hour in lowes rewinding

Gonna try this to my bicycle bottom bracket.

Can this be used to power something
Would it be better to put more sticks with coils
What happens if the motor tree is made of iron? Thanks 7:29
What would be some ways to maximize the output? Is it better to have a bigger pipe, or smaller? ect
Smaller
i like this video👍
'at's a bad ass item!
The wire coils on mine are getting really hot, can soneone explaiin? Im using a Milwaukee battery, shoukd i use some 9 volt batterys
Can you explain how Flemings left hand rule would apply to this motor?
23:40 if you mark with a sharpie first, then scribe with the calipers, you will achieve a more accurate, fine line.
No swearing, i'm doing a video. Lol what a bad ass teacher. Can tell it is probably an awesome learning environment.
If the wire is not insulated, how could you wrap it around on its self without it shot circuiting the coils and just taking the short cut through all the wires that are touching?
"You sure it's recording?"
"Yes!"

Hey man, great vid! What if I use a plastic pen as the armature? Will it work just like yours?
If you were to use a plastic pen as an armature, it wont create such a strong magnetic field around the copper wire, it will still work just not as much torque
Tyrone Elvy Thanks man!
no problem, its just using the steel armature amplifies the magnetic field. hope this helps
Tyrone Elvy yup, I wrote about plastic pen but I used bolts for my motor... Yeah, your comment helped me understanding the fact ☺️
awesome, i gotta build one for my year 12 physics assignment
Hopefully my dad will help me buy the supplies for this.
I have used all pin as brush
Chris O'Dowd teaches electricity!

Is that wire insulated, or is it naked copper wire?
Insulated
Wow
I’d like to send you a picture of the ones we made in 1964 how would I do that
If one was to take this class, what is the actual name of this class?
i could use cardboard right?
FWe made a far more sophisticated one of these in ninth grade in 1964. For shop class
i made it for a science fare

Sir it is not rotating
its very sensitive to any mistakes, so make sure you made it correctly
I think the rod is too long and the magnets are too far apart. Also I had to insulate the threaded rod to get the electromagnet to work.
