Great job. Such patience and persistence. You must be a great father too.

Nice work! I've been in the electrical industry for 20 years and I just learned something! Good to see a win for the good guys.

Thank you for taking the time to share your knowledge. I am repairing my pool robotic cleaner, and need to replace the impeller motor brushes. I originally thought I'd have to solder the replacements' copper wiring onto the circuit board itself, but seeing your technique gave me just the info I needed! I appreciate your help!

Thank you so much man! This was very helpful! Keep it up! Took me ages to find brushes at a local store!! Finally found one at an old Mom and Pop store 20 minutes away! Now I spent $9 for my fuel pump instead of $300 by just changing the brushes in the motor! Cheers mate!

Wow what a great daddy’s helper. You’re more than welcome to Sheffield England after the Covid-19 pandemic is finally over. That was a great video my friend, really useful.

Wow, what a great vid! I quickly realized it's not the motor that I'm working on, but I couldn't stop watching - great angle, very good lighting, very clear and a thorough explanation. Good job, dude :-)

Really like repair jobs - and re purposing. Well done

The "thing" that the brushes ride on is called a commutator. If the brushes are as worn as the ones pictured you should check the commutator to see if the mica needs undercutting. If the commutator is worn to the same diameter as the mica then the harder mica will eat away the new brushes and/or cause the brushes to chatter. But you can often get away with one brush change without undercutting. Luckily for all of us BLDC motors are coming into play and we won't need brushes.

They are called brushes. What they brush against is called the armature. They do not 'alternately contact' the armature. They constantly contact it. Using the new springs, even cut down, gave them the wrong pressure. Too little and the brushes will stick in their carriers. Too much pressure, and the brushes will wear out prematurely. Good job, though! Most people wouldn't even try. :)

Thank you very much! You just saved me the expense of replacing my reciprocating saw. Awesome! Thanks again.

Excellent tutorial, Carbon Brushes are very easy to alter sizes..Sand paper eats away at the carbon very aggressively..long as you avoid the area where the copper conductor is embedded

thanks man that just saved me $200 really appreciated man.

Nicely explained. Thank you. I have the same problem with the motor 4 my blower....I know now how to fix it. Good job.

Wow!! Thanks a lot! I'm wondering if I can use this knowledge to fix my car's radiator cooling fan instead of paying $700 for a new one.

this video is just incredible. thank you!

Woo hoo! Great to see the result of persistence :)

Beautiful. These days, people are so quick to toss it out, and buy new. Nobody looks into why it failed. Funny thing is, a lot of times, it's something as simple as this. Kind of a lost art...

Thank you. You just saved me $100 now and probably a lot more in the future.

Super excellent video. Great explanation.

I just took apart my sterling sewing machine and they all fell out- So the springs goes inside first then the square? I have a 120 motor 110-115 cycles 25-75 & DC

Really good info, thanks.

Great video! Exactly how much were you adjusting your seat back though?

So, if I cannot find the right size motor brush, can I just re-size a larger one?

great video

My saw and router came with extra brushes. I had no idea what they were until I saw this video.

how do you wear out the brushes of your seat adjustment ? Do you move it 10h a day ?

is it true that carbon and pencil lead are same

My electric leaf blower abruptly started to smell and lose power. I watched this video and figured I'd do much the same. So disassembled the motor. I removed the brushes (which were in good shape) and lightly sanded the commutator. I reassembled it and it started just fine and at full power but quickly started to small and to lose power. Any ideas on what to check next?

great job. BTW this is were a dremmel sander would have come in handy.

nice work

thanks so much!

I just finished SANDING down some carbon brushes to fit my jigsaw motor as they didn't have the right size, then I found the whole jig saw used but excellent condition on ebay for $8 :(

Most Motor using brushes to convert from D.C. to A.C., the design is spring pushed the brushes touch near the armature to rotate strong magnet rotate back and forward to create Alternator current , brushes is cheap , brushes can grind down certain size.

excellent

Can anyone help. What would cause an electric motor to get weak over time and how can I fix it. What would cause it he hear up also

thank you

Arron did all the work. You could have have completed this project without.

Nice

Good hands .

Still don't understand why the carbon didn't push out with spring behind

Oh i thought my volume was down, my jack not connecting properly, or my headset in wrong place... Im stoned was confused

I think the star of this clip was your cute son, I mean assistant. :~)'

the measurments of the carbon brushes should be 4 mm x 4mm x 10 mm (milimetre). you said centimetre. you meant the measurments of the carbon brushes right ? great video thanks alot.

ahh the Ole weekend project.

I have a 1927 WHITE brand electric machine, the motor works but smells funny and I can feel a vibration when I touch it, not grounded? also, the electric cord (inside the motor) is old cracked rubber covered with cloth. the machine is great. does anyone know how to RE-WIRE this scary machine. I don't want a shock or a fire, thanks I like your instructions about the brushes.

USE Proper soldier...USE Heat sinks !! USE Very Little soldier!..Just enough for a good small connection

I have change my auto gate carbon brush

That's how I fix my starters and alternator people dont realize how much money you can save fixing stuff this way

i bought mine off mrcarbonbrush top quality cheapest online store with free delivery

The back plate of the motor where the brush assembly is, there should be two holes. If you push the brushes back in their slots, take toothpicks and stick them in those two holes. They'll hold the brushes back for you until you get them over the commutator. Then just pull them out once in place.

I know how to replace brushes. what I need to know is where to buy brushes for my weed eater.

D

You have a kid around, so I'm guessing there is a woman too. Steal an emery board from her next time. Much easier than an xacto knife, and one of the few logical reasons to keep a woman around.

just smelt that flux from here ha ha

thumb up for the communist China reference!

Got these from my good friends.. communist china. Brilliant line, I'll be saying that from now on.🤘🤘

SPEAK LOUDER PLEASE, I HAD TO TURN MY VOLUME TO MAXXXX.

Trouble hearing you.

I am just hearing impaired enough to not understand a mumbling word. For God's sake uou people out there, if you are going to narrate video - please speak clearly and loud enough for normal face to face converation, or get some one to do it who can. Drone on Buddy. I would love to - no, NEED to get your much needed advise loud enough to hear. Are you just bashfull, or what. You are not the only one like this. Pissed off, on foot, handicapped chair rider

Sorry -- this is a good effort. But the narrator either does not understand the technology, or the terminology used to describe it. Those are brushes, not contactors. That is an armature, not a shiny round thingie. That is a braided connector, not a copper thread. Use words, and we'll all become better technicians. Recommend you go elsewhere to avoid some of the bad advice imbedded here.
