. It is widely used as a stock component in Creality 3D printers, such as the Ender 3 and CR-10 series, typically serving as the Y-axis motor Technical Specifications
As a NEMA 17 frame size motor, the BJ42D15-26V10 adheres to standard mounting patterns, making it compatible with most off-the-shelf brackets and extrusions. 42.3mm x 42.3mm Body Length: 40mm (approximate) 4-wire bipolar configuration is standard for these models
The alphanumeric code stamped on the back of the casing contains specific physical and electrical attributes defined by Keli Motor's catalog scheme:
This four-wire bipolar winding arrangement enables the motor to be driven with higher torque compared to unipolar configurations. The fifth was labeled
Engineering Reference Document Type: Simulated Datasheet Review Date: April 21, 2026
user wants a long article about the "bj42d15 26v10 stepper motor datasheet". This appears to be a specific stepper motor model. I need to provide a comprehensive datasheet and application guide. To do this, I need to gather technical specifications, manufacturer information, and application examples. I will perform multiple searches to cover all these aspects. search results show several potentially relevant pages. I should open them to gather detailed information. The most promising seem to be result 0 from the first search (KELI product page), result 5 from the first search (a Russian forum post mentioning the motor), and result 0 from the fourth search (a review of a laser engraver using the motor). I will also open result 1 from the second search (Elegoo Neptune 4 identification guide), result 1 from the third search (Russian forum post about Elegoo Neptune 3 Pro), and result 0 from the fifth search (Raspberry Pi forum). search results provide some useful information. The KELI page (result 0) shows a table of technical parameters for the BJ42D series, which is relevant. The Russian forum post (result 5) confirms the motor is used in a Creality Ender 3 S1 Pro. The TOOCA Laser L1 review (result 0) mentions the motor is used in a laser engraver. The Elegoo Neptune 4 guide (result 1) provides identification details. The Russian forum post about Elegoo Neptune 3 Pro (result 1) provides some parameters. The Raspberry Pi forum post (result 0) mentions the motor is NEMA-17 and provides a link to a datasheet for a related model. I also see results for "BJ42D-E Closed-Loop Stepper", which might be related. I'll open the closed-loop stepper page to see if it contains relevant datasheet information. search results provide a good basis for the article. I will structure the article to include: an introduction to the motor, its key specifications including a datasheet table, an in-depth analysis of the model number, its common applications, compatible drivers, wiring and configuration guidance, physical dimensions, alternative options and upgrades, and a conclusion. I will cite the relevant sources. BJ42D15-26V10 is a NEMA 17 hybrid stepper motor, renowned as the standard motion component in many 3D printers, laser engravers, and CNC machines. This article provides a comprehensive datasheet, technical specifications, and application guidance for this reliable and popular motor.
While the motor is rated for ~2.6V, chopper drivers typically supply 12V, 24V, or 36V to the driver board. The driver chops the voltage to maintain the set current limit (1.5A).
