While community members often mistake these for high-current 1.5A motors, official specifications for the BJ42D15 series confirm a lower, more efficient current rating. Specification 1.8° (200 steps per revolution) Rated Current 0.84A – 0.9A per phase Maximum Input Voltage Holding Torque 2.86 kg·cm to 4.0 kg·cm (approx. 0.28–0.4 N·m) Form Factor NEMA 17 (42 x 42 mm) Motor Height 34 mm (Standard "42-34" size) Shaft Diameter 5 mm (D-shape or round) Phase Number Internal Wiring and Phase Identification bj42d15 26v10 stepper motor datasheet exclusive
: This suffix often denotes specific winding characteristics or factory-set voltage/current revisions. For example, while widely assumed to be 1.5 A, "26V" series motors are confirmed by manufacturer-reaching enthusiasts to actually be rated at 0.84 A . Practical Application & Safety : 5mm diameter, often with a "D-shape" or
It typically features a standard 4-pin JST-PH connector, but always verify the pinout for "A+ A- B+ B-" configuration as some Creality cables cross the middle two wires. : 5mm diameter
