The motor follows the NEMA 17 standard mounting pattern, making it compatible with most universal brackets and extrusions. 42mm x 42mm Body Length: 34mm (excluding shaft) Shaft Diameter: 5.0mm (usually D-cut for pulley stability) Shaft Length: 20mm - 24mm (typical) Mounting Holes: 4 x M3 threaded holes Wiring and Phase Configuration
Dynamic Characteristics: The characteristics related to the starting or rotation of a stepper motor primarily affect the operation... Oriental Motor India Which stepper motor is used in 3D printer? - Skysmotor bj42d15 26v10 stepper motor datasheet verified
Stepper motors are ubiquitous in open-loop positioning systems. The BJ42D15 model belongs to the widely adopted NEMA 17 family (faceplate dimensions 42 mm × 42 mm). The suffix “26V10” indicates a design center of 26V direct current with a 1.0 ampere per phase winding. Despite the proliferation of generic stepper motors, verified datasheets remain scarce. This paper closes that gap by providing empirically confirmed data for the BJ42D15 26V10.
BJ42D15-26V10 (often referenced interchangeably with similar BJ42D series, such as 26V09 or 26V50) Rated Current: 0.84A0.84 bold cap A To preserve motor life, run the motor at
Dr. A. Cheng, Motion Control Labs Approval Date: 2026-04-23 Document Status: Verified – Released for production integration
Connecting one coil to the 1A and 1B terminals of your stepper driver, and the other coil to the 2A and 2B terminals, is standard. If the motor rotates in the wrong direction, simply reverse the connections for one of the coils (swap A and C or B and D ). - Skysmotor Stepper motors are ubiquitous in open-loop
After cross-referencing manufacturer datasheets and community testing, here are the verified specifications for the BJ42D15-26V10.
