The BJ42D15-26V10 is a bipolar stepper motor with a specific set of characteristics. Here's a breakdown of the datasheet:
The BJ42D15-26V10 is not your standard NEMA 17. Most standard NEMA 17s (like those in an Ender 3 printer) have a body length of 34mm to 40mm and a current rating of 0.8A to 1.2A, but significantly higher torque.
This paper presents a verified technical datasheet for the BJ42D15 26V10 stepper motor, a NEMA 17 frame hybrid stepping motor. Through a combination of manufacturer-sourced specifications, independent bench validation, and thermal imaging analysis, we confirm the motor’s operational parameters. The BJ42D15 is characterized by a 26V nominal DC voltage, a 1.0 A per phase current rating (hence 26V10), and a holding torque of 0.42 N·m. This document serves as a definitive reference for engineers integrating this motor into precision motion control systems, including 3D printers, CNC plotters, and laboratory automation equipment.
