How strong are these little stepper motors?
How strong are these little stepper motors? I've got some answers!
I've been using these a lot lately, both in my 3D printers and on some other machines that I'm building, so I wanted to get to the bottom of this! I figured the only way to really do it properly was to go all out. Load cell, spreadsheets, and everything.
Long story short, you can get a little less than half of the rated holding torque when driving a load, assuming you're conservative with your speed and acceleration settings. Holding torque is just the locked rotor torque (the ability to hold a load in place), which I also tested. Unsurprisingly, my results were very close to the rated value, although drive settings really matter.
So if you're used to using steppers in linear motion applications (like 3D printers), 100 RPMs is about 67 mm/s with a typical belt drive printer. In terms of acceleration, 100 rev/s^2 is about 4000 mm/s^2. This would partially explain the print quality limitations at higher speeds with many printers.
