Given it's a NEMA 17 (42mm) stepper:

The model number itself tells us almost everything we need to know about the physical form factor and electrical characteristics of this motor. Let’s decode the nomenclature: Based on cross-referencing with similar NEMA 17 hybrids

Given its specific voltage and current characteristics, this motor excels in: Given its specific voltage and current characteristics, this

Unlike standard motors, the 26V input allows this unit to maintain 80% of its holding torque up to 300 pulses per second (PPS). Here is the exclusive performance curve summary:

Recommendation: Operate between 150 and 500 PPS for optimal smoothness with a 26V microstepping driver (e.g., 1/8th step mode).
