Stepper motors generally are not available in frame sizes larger than NEMA 34, with most applications falling in NEMA 17 or NEMA 23 motor sizes. As a result, it is unusual to find stepper motors ...

With the same physical dimensions as standard NEMA 23, 24 and 34 stepper motors, PowerPlus Hybrid Stepper Motors often drop into place to minimize upgrade costs while improving performance. The ...

Nanotec has created low-noise planetary gearboxes for brushless DC and stepper motors with NEMA 17 flanges (42mm, 1.7in). “With the GP42-N series,” according to the company, “the helical toothing ...

In those mechanisms, a high-torque, low backlash gearbox might be just the thing, and a 3D printable split planetary harmonic drive for the popular NEMA 17 motors would be even better.
