| Parameter | Typical / Assumed Value | |---|---| | Frame size | 42 mm | | Step angle | 1.8° | | Rated voltage | 26 V | | Rated current | 10 A | | Phase resistance | ~2.6 Ω (estimate) | | Inductance | 1–10 mH | | Holding torque | 0.3–0.8 N·m | | Shaft dia. | 5 mm | | Mounting | NEMA17 pattern |

If you see a voltage listing on a sticker saying "12V" or "24V," be careful. Stepper motors are current-driven devices. The "26V10" code strongly suggests a winding resistance of roughly 2.6Ω. If you apply 26V directly without a chopper driver, you will burn the motor instantly. Always use a current-limiting driver.
