BJ42D15-26V10 is a NEMA 17 stepper motor frequently used by Creality in their 3D printers, specifically for the Y and Z axes. While detailed official datasheets can be difficult to find, technical specifications from manufacturer Keli Motor and translated sources reveal its core operational parameters. Core Technical Specifications Form Factor : NEMA 17 (42 x 42 mm). Step Angle : 1.8° (200 steps per revolution). Rated Current

The is a specialized NEMA 17 stepper motor optimized for 24V–28V systems requiring moderate torque at low to medium speeds . Its 26Ω phase resistance and 1.0A current rating make it an energy-conscious choice for precision positioning, not brute force. When paired with a modern microstepping driver (e.g., TMC2209 at 26V, 1.0A), it delivers smooth, quiet motion for desktop automation, medical devices, and light industrial equipment.
