57BYGH242C-46 stepper motor

These details belong to the SKU and are shared by its batches.

Label reads 57BYGH242C-46; no manufacturer name visible. NEMA 23 and two-phase bipolar arrangement accepted by the user; four external leads observed. Shaft diameter approximately 10 mm and across-flats approximately 6 mm, measured with an inch micrometer. Shaft projection approximately 37 mm from the flat motor face, measured with a ruler. Body length estimated 54–56 mm; structured value 55 mm represents the midpoint of that estimate, not an exact specification. Body width and height were not measured and are left unset. Two broad opposing shaft flats; their axial length was not recorded. Hybrid construction and 1.8-degree full steps (200 per revolution) remain plausible family-level guesses, not confirmed specifications. Manufacturer, rated current/voltage, resistance, inductance, and torque are unknown. Wantai's linked 57BYGH page describes related motors but does not list this exact model.
