Bj42d15 26v10 Stepper Motor - Datasheet Exclusive

The BJ42D15-26V10 is a "short stack" motor. Compared to the standard 40mm or 48mm tall NEMA 17 motors used for heavy-duty CNC work, this motor has lower torque but higher speed capabilities and lower inertia.

For engineers: Always drive this motor with a voltage source at or near 26V for optimal torque-speed flatness. Do not substitute a 12V-rated driver without recalculating current limits. bj42d15 26v10 stepper motor datasheet exclusive

: While some generic 42-34 motors are rated at 1.5A, the BJ42D15 series used by Creality is specifically tuned for lower current (~0.84A) to maintain thermal stability. Holding Torque : Approximately 2.86 kg·cm (0.28 N·m). Dimensions : 42 x 42 x 34 mm (Standard NEMA 17 "42-34" frame). Shaft Diameter Input Voltage : Maximum 24V DC.
