Selecting the right stepper motor - Torque test of Nema17 and geared Nema17

In this episode we talk about how to convert the torque specifications in Newtonmeter to something more graspable, like kg/m, or lb/inch. We look at the datasheet of a Nema17, and field-test our conversion with different weights. A 27:1 metal-geared Nema17 will also be put to the test, lifting 2.5kg.

I am quite new to producing videos, so I am super thankful for tips, comments and suggestions on how to improve!

(P.S.: I noticed the irritating focus-behavior too late, next time I will set it to manual focus)

Great presentation, including the final fuck up, which added a nice touch to the video. Keep it up!

I actually knew it was gonna happen, even before you put the weights, just by looking at the clamp, and I was thinking "what is this guy thinking, it was obvious it wasn't gonna hold the weight".. But that was a great demo. At least no foot was harmed.

Thanks, you make me laugh too much in a moment that i not spectate. Nice video. Thanks for share.

Wow! That was a ... nice(!?) video? You gotta have a look at your autofocus - use a fixed focus instead. Greetings from Germany - you just got a new subscription

Lol, it was at this moment, that he realized, he fucked up.

[diegogarrido]

Awesome video! It would be interesting if u make some tests to analyse the Torque x RPM curve too

[zandervanderwatt]

Really great vid to demonstrate calculated concepts practically!

[easy_engineering_drawing]

Was searching this. Got this and understood clearly. Appreciate the Great work. Thanks a ton.

[andrewmagdaleno]

Loved the video!
But yea, the autofocus was going crazy. I dont know how to fix that but i would love you to do more on motor reviews, part reviews and how to for diy projects! You earned another sub!

[tllvllp]

Haha, great video! And actually the first useful one that I've found on the topic, thanks!

[DIYMachines]

Great video and information. Thank you.

[vipulfpv]

Thanks for the best video every thing clear in 5 min
Understand thanks again

6:18 sehr schön! xD
Und direkt mal der Beweis, dass da einiges an Gewicht dran hängt.
Und super Video!!

[viyugunmj]

Thank u for better practical explanation.

[KlauV]

That was awesome man! Made me laugh so hard! And thanks for the info!

[MattSeals]

Sustain the great job and generating the crowd!

[travisgillespie]

Thanks for the info. Great video. Loved your creativity + commentary 😂🤣😂

[joemulkerins]

😂 I f*n knew something was going to go! Was surprised at the motor power, well done, but my instincts told me something was guna happen. Funny one lads 😂

[CuddleStories]

Bravo. Amazing explanation. Great for us beginners.
