What's the best NEMA23 Stepper/Servo? | Electronic Leadscrew Part 24

What is the best stepper or servo motor for the Electronic Leadscrew? I've collected some suitable candidates and today we're going to test open-loop steppers, closed-loop steppers, and a true servo from ClearPath to see how they stack up.

You deserve far more viewers with content like this.

This is some thorough testing but when you know your stuff, you know your stuff. Thanks for your effort 👍

[paulsanders]

Excellent video and testing. As I always tell my engineers in the words of the great W.Edwards Deming "without data you are just another person with an opinion"

[simonconvey]

Wow ! At last, an objective test. I've learned alot. Yes, and pinch of salt is always to be taken when reading specs, but your tests are truly revealing. The important point here is the test method, and not subjective reviews. Data doesn't lie, manufacturers do.... Well done, keep it at it.

Fantastic testing and thoroughness. Thanks for the video

[telelaci]

I just found you today, and I like your videos. Pure simple engineer mindset you have, very smart one.

[CraftedChannel]

I always learning something listening to your videos. And that is saying something since my wife constantly reminds me that I know everything. Look forward to the follow on video.

Thank you for this detailed test, this is very valuable for making an educated decision. I was considering going with closed loop, just because it's supposedly better, but seeing this, at the rpm I'll be using it, the difference to a digital driver is very small! You just saved me some money.

Most excellent analysis...hmmm, now I understand why I’ve been creating “multi-start” threads so successfully 🤔

[BM-jycb]

Excellent testing. Just the right amount of introduction upfront and then into the testing. Your production skills are fantastic. Thank you!

[emreceylan]

Best video on this topic after watching several videos, thank you.

[bobvines]

James, thank you for an intelligent comparison of these motors. Your channel is one of the _few_ channels where I'm impressed with content _and_ intelligence.

[routercnc]

Well done James for putting in the effort to set all this up and do the editing! My CNC router runs 3Nm steppers on old analogue 80V drivers but I’m running at 70V as this really boosts the output over 48V.

[Mike-ffib]

One of my favorite channels. Quality content.

[raikbusse]

Very understandably explained, even for non-English speakers. One of the best videos I have ever seen. Please keep it up! Thumbs up!

[rpavlik]

"I'm all out of motors" and presumably money, given the price of some of these motors, yikes! Nice procedure and results!

[jrace]

Great comparison! Thank you for testing these so thoroughly and reporting your results.

[tonyurquhart]

Thanks James. As always a very informative lesson & clearly articulated. You have a real gift in being able to show & explain complicated technical details in a way that most laymen can understand. Keep up the interesting videos, please... :) (& I like your quiet dry sense of humour too).

[TaYpworm]

"This is why we test". Top-notch video!

[adaptedmachining]

Perhaps the best thing I've watched on YouTube this year. Well done. Great content. 👍
