How to attach something to a smooth stepper motor shaft

- This quick video tutorial shows you one way of attaching something to a stepper motor shaft. Stepper motors are great but their shafts are often smooth and without screw holes which makes attaching other parts difficult. In this how-to video we show you how a universal mounting hub works.
THANK YOU it's one of those things that's just SO common sense but for whatever reason was just slipping my mind!
A better way would be to take a grinder disk and make a flattened edge for your tightening screw to sit on so it doesn’t slide after a bit of use ;)
Thank you very much! As a beginner it helps me so much!
Oh man.. thank you! I was wondering this for so long... Thanks again for sharing~
Thanks for this video. I was sooooo baffled when I got this nema 23 stepper motor that had a smooth shaft! Now I know how to actually tie into it LOL!
+gardogg65 LOL? You just say LOL at the end of a sentence like that? I'm already angry at the stupid shaft manufacturers and now I have to read LOLs from stupid commenters who copy mainstream society. Stop following people!
+Zxenmusic the stupidity of the shaft design is why I lol. It shouldn't be so hard to figure out but it is thanks to dumb design.
LOL haaaaaaaaaaaaaaaaaaaaa!!!!!!
Thank you! Very informative.
"this happened to us once" says text-to-speech synthesizer!!
Yup, robots are in the family now, we might as well get used to it
Thanks. Really helpful!
theyre called shaft adapters on aliex
Thank you very much
Nice idea👍👍
Is this serious? And if I come across a motor with no flat on the shaft I get out my file. Ten seconds will put on enough of a flat to securely lock a set screw without excessive tightening.
You are a good man. Some of us aren't very good with our...hands.
use a clamping hub?
What did you call that ring in mechanical term ? I'm finding the big one for 220v 1 phase motor with diameter about 1cm
can you tell me where to buy this mounting bracket--i could really use this
Great idea to limit the message to one minute. This requires careful phrasing of the video title to communicate the content. Thank you for sharing.
"flange coupling"
is there a way to do this without a mounting hub?
I'm not a big fan of this strategy. Using a set screw puts a lot of torsion stress on a small set screw. I'm typically use 3-6mm shafts so especially for the 3mm shafts using a Dremel nut and collet works really well. These little collets are made for holding small drills and the motor shafts are about the same size as a drill bit.
The best part is Dremel tools and accessories are widely available and cheaper than this solution.
Now why did I not think of that. Excellent solution as well.
***** I found some collets that were meant for model aircraft props that work a treat for 3mm.
+Dennis Furr Oh my God. You guys are not even complaining that the idiot manufacturers made a smooth useless shaft on every stepper motor in the world for no reason whatsoever. Instead you're finding makeshift solutions to deal with it like trodden-on rodents. RISE, PEOPLE! Be good global citizens and actually matter. Complain when things make the world worse.
Dennis Furr, your strategy is off; this is not the forum for the uprising that you propose and it will not affect, in any way, the manufacturer's production design.
Mark - I didn't suggest that it would change the design but merely suggested using a collet. I think you were referring to Zxenmusic's comment. If I recall correctly instead of using a Dremel nut and collet I bought a collet for mounting a RC aircraft prop to a motor and swapped out the elliptical nut for a piece of ID threaded steel tubing that I fabricated.
If I was really smart I would have built in a flexible coupling to reduce bearing wear. Live and learn.
I still do not know what to attach to my many motors. *HELP!*
How do you mount the second shaft to the hub using the 4 holes ?
use another hub on the 2nd shaft? lol
You'll want to use a shaft coupler, not what's in this video.
Exactly what I was thinking. It's a never ending story. You end up buying tons of couplers, adapters, reducers, chucks, plenty of machines (to make the perfect fkn fitting)... and in the end the attachment is so heavy that unbalances it all. Maybe it's just better to buy a fkn expensive motor with all its fkn accessories (if there even is such a thing).
u could just make indents.
Where do you buy the coupling?
at a shop
Or use a shaft arbor
props to the sexy narrator
Mine doesnt have a hole
Where do you get this part? Whole video is useless without that information.....
Hi folks, I have a 28BYJ-48 stepper motor, has anyone seen anything for coupling this motor? as you probably know the shaft is not perfectly round, ( It has a flat edge on either side )... Thanks, John... :)
John Berry man .. i have been scrolling down all over the net to find someone talking about this it's my 3rd day searching for how to solve this problem and idk how yet did u find any solution ?
Check out mcmasters industrial website
This is dumb.. Collar for a nema 23 is 2.99 drill into that
I hate it when you can't screw further.
wtf?
Why dont they just make a D shaped shaft or give it a spline like normal shafts? Thats fucking stupid.
agreed.
What if the orientation of the motor is so that the shaft is pointing downward. The D shaped/Splined shaft wont be able to hold the other shaft because nothing is holding it up against gravity. A shaft coupling is a better idea but this could work if space is an issue.
