Had to take the adverts off - TH-cam is taking the piss with so many ads. If you have the dollars to spare - you can always buy us a beer. Any beer donations appreciated. (Do not buy me a beer if you are a poor student!)

+Tim Callinan Don't apologize. You are taking your time to make a video to educate people. If you make money out of it, take it as a thanks from thanks from your viewers. By the way Thanks for making the video.
I'm happy to exchange a couple extra seconds for you benefiting from this video. Thanks man!
Excellent example of a simple dc brushed motor generator, thank you!
This is amazing, i wish you were my lecturer back in the day.
This is the best demonstration out of everyone!!! Thanks for sharing.
Thank you so much for this video, couldn't find another one like it!
Good one! Great to see it working
This was very helpful. Thank you. :D
McMaster-Carr FTW !!! Nice Motor Man !!!
Very cool project. I bet if you shortened the threaded rod and reduced the air gap you could really get that thing moving.
this was used for my hsc. cool video!
Tim . I need a 1 or 2 HP motor. do I just add more raps to the copper ?
I miss Radio Shack... 😢
I altered my electric guitar so many times with parts from there. Up to this day, nobody knows how it sounds so clean. That's when I was a middle schooler. Can't imagine what I'd be able pull of nowadays. Electronic stores can be a bit pricey; but, i have no other choice
dude need help....can i do dis instead of two magnet wire part can i do 6 or more?
I was just wondering if this could work with a 2 volt power supply?
Nice video. Thanks for sharing
Does it start from automatically from horizontal position?
Nice Job man!, Very helpful as well, hope you made some money of this.
Thanks for your helpful video hairy Irish tutor mon👍🏼
Do the armature need to be mettalic? can I use something like plastic or paper or clay?
If you add a resistor to the circuit, will it make the motor go slower?
excellent video and motor
Great video. Thanks : )
How many volts does it take to run
hey, I need to build a dc motor for school can someone tell me all the materials he used, mainly the (blue tack stuff). thanks.
slick and cost efficient
Simple and great thanks
Will it work with a battery?
how many times did you wound the copper wire? how much copper wire did you use?
i would suggest wrapping over 200 wraps on each side.. with .22 guage wire.... wrap more with thinner wire.
good video
What can I check if It doesn't work?
what is wrapped around the 1/2 inch pipe to place the commutator on? and how do you attach the commutator onto that?
Just electrical tape to widen a bit. I used super glue to attach it.
what wire is this?? where can I get it? and can I use this wire for a simple dc motor aswell? would appreciate feedback, I need to pick this wire up for a school project. (where can I buy it?)
Sayton Dette you can order it, it is called "magnet wire" or "Enameled wire* and it is made for winding coils
I have always wanted to build on of these. but I was never sure how to wind the copper. Is there only one way to wind it? You use 1 long piece of wire, don't you? and then you keep winding say, clockwise all the way up the bolt?
boowonder888 yes wind it in one direction
yes.
Omg, thank you very much, I understand now, thank you.
Was the amount of turns of wire the same on each side? I'm doing a school project and i'm having trouble
Yeah they should be even.
put over 200 wraps on each side of the bolt, if you cut corners & skipm on winding , it will cause problems.. good luck
Overnight project? Im doing this and i have like a week and i am still struggling to get it done.
Yeah I can definitely see this taking a week to do. With my students, all the materials are ready for them. I think retrieving the materials is half the work. I hope you got it working. I feel like its beneficial to build motors by hand - than looking at a powerpoint about it.
Would this work with a normal battery? 9v or 1.5 in series for example... I need a quick answer, would be really grateful! We have to make an electromotor for our school, it has to run for 1 minute and run from a battery.
Should work with 9v I would built a smaller dc motor. There are loads of designs out there. This is a bit more difficult
@@timcallinan I built a smaller one last night with a 6V lamp battery, was so happy when it worked! Thanks for the great video and the reply. :)
your a good teacher, tim
Would a flywheel help on this motor? I did make mine, got it running and everything, but it stops sometimes since the rotation is not smooth. It can even lift some weight.. yey! lol
Nice one! A flywheel might help but what sort of voltage are you running - at least 5V i would think. You could mess around with the position of the commutator.- This might help. Glad you got something running.
+Tim Callinan Was running it at 10V and 2,2A. 2,6A when the commutators shortened out for a second. Might try to build a new one with 3 armature ends and a flywheel. And thanks for the video, it did help me out a lot with my project.
Can you please post a list of what is needed to replicate this DC Motor
thanks
Quack
Hey could you tell me how you got the magnet wire to reach the shaft
heyyyyy
hello :3
I'm building a very similar motor to this one, but sparks keep being produced between the brushes and commutator. How can I prevent this?
Weaselskey probably the angle of your conductors and how they interact violently agaisnt each other, repositioning will do
its a common problem with DC brushes... the better the contact to commutator, the less sparks...
did you coil the whole rod? and how did you put in the nut? Im havng a hard time with that
+Fardin Kibria rod the tor pasa dia dhukai te hobe aage, then you can nut. Ur welcome, happy to help :)
+Shadman Aziz (TheRealShadyMan) tor baap tor kajer bua'r shathe raate ki kore jaante chai nai
tai naki mothersood :P
You put the nuts on either side first - tighten them and then start winding the magnetic wire.
hey I am making one and I can't figure out what is under the commutater is it just electrical tape?
Xavier Grone yes, it is used to fill the space between the tube and commutator
and the magnet wire is soldered to it as well
Where did you buy the wire and threaded rod, and does the armature (threaded rod) have to be a conducter
The wire can be bought from www.mcmaster.com - it is just normal magnet wire. The threaded rod is made from steel - the important thing is that it is ferrous (magnetic) it should stick to a magnet.
any hardware store , such as lowes, should have the " all-threaded rod" and the copper pipe plumbing straps ( commutator )..
how to make a missing part of dc motor the plastic with 2 conectors ? please help me
Fawks I do not understand your question
How did you connect the wire to the commutator?
Therese J use a soldering iron and solder
it needs to be an electrical connection
I have 32 gauge magnet wire, I am getting no current to my coils but commutator is sparking on turn. Is the wire too small? Should I just rewind it?
I would guess the insulation needs to be burned off the magnet wire
@@timcallinan the whole wire or just the connections?
Just the connections where you are soldiering it.
how did you attach the commutator? To the shaft
Kuta
Super glue, or hot glue
What could my problem be if my coils do have a magnetic field, but still attract the magnets on each side instead of repelling them?
your magnet poles are backwards...
@@guitarman_3693 lol I figured it out. I uploaded a video of this exact design for a class I was doing this for at the time. Appreciate the help tho, I was pretty desperate a year ago and hadn't taken electromagnetics yet.
@@Not_Valentine hello I’m having this same issue of both ends of my electromagnet attracting the permanent magnet, I’m curious to how you were able to fix this? Thank you
@@rogerhornsby8180 you have to really pay attention to the direction you are winding your coils. If you started clockwise then it must be clockwise throughout both sides of your core. My problem was that when I finished one side, I flipped to the other and kept winding clockwise, but since I flipped sides, it actually make the other end counter clockwise so the polarity never changed to keep the motor moving. I'm not sure if that made sense, but let me know and I can try to explain again.
Bolt cutters
Hmmm... I'm gonna needs some chewbs...
I want to see you Pull apart random junk and make it work for the price of like garbage speakers and scrap wood and even steal some bearings from something . Well im gonna do that now i guess....
What is under the commutator?
denneka adlam it is tape, to make a bigger diameter for the commutator
i wish if all my Drs and Teachers was like you
Not working
Copper is magnetic?.. wut
Jack Duno its laced with copper the inside is probably zinc or iron
Bawz Games Huh, wouldn't have thought that
Lol RadioShack
you sound exactly like Tom Green in Freddy Got Fingered
check12 thismicon No, he really doesn't.
Johnjohntv 69 yea he does. what are u 12 years old....dont u have homework to do
check12 thismicon Is that the way you deal with people when they have a different opinion to you, you just insult them? How juvenile.
Johnjohntv 69 how about who gives a shit if you DONT think he does
Chill the fuck out lads will you.
Ah...Stupid, stupid. Was that what it was missing? The iron core inside the coils? Haha, it was never going to work. Ok ok. I'll fix that. Thanks for the video.
[Overtly loud] "This is lame! NOBODY wants to build this crap, except for maybe some nerd!!!"
[Whispers] "Hiiii....just so I can confirm how stupid this is, and for NO OTHER REASON...you DID say 1/2" tubing for the interior shaft...correct? 🤔...okay...good. [recklessly drives to Lowe's]
😉
respect. its comments like this that make my day
