The is a specific NEMA 17 stepper motor commonly found in Creality 3D printers, such as the Ender 3 series. While an "exclusive" datasheet isn't publicly indexed by the manufacturer as a single PDF, technical specifications have been verified through direct manufacturer inquiries and community benchmarking. Core Specifications

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.

align closely with other "BJ42D15" variants used for X, Y, and Z-axis movements: : 1.8∘1.8 raised to the composed with power (standard 200 steps per full rotation).
