Finding the Best NEMA17 Stepper Motor: LDO Motors, STEPPERONLINE and more tested with a dynamometer

Video Description

NEMA17 motors are ubiquitous, and sometimes they even look identical. How do we know which motors will perform the best, and is there even a best motor for every application? In this video, we test five NEMA17 stepper motors with a dynamometer and examine their speed-torque curves to find which motor performs the best.
