Bj42d15 26v10 Stepper Motor Datasheet Verified

Before we get to the verified specs, let's decode the model number. This standard naming convention tells us the physical size of the motor before we even look at a datasheet:

| Driver Type | Connect A+ | Connect A- | Connect B+ | Connect B- | | :--- | :--- | :--- | :--- | :--- | | TMC2208/2209 | Red | Green | Blue | Black | | A4988 | Red | Green | Blue | Black | | DRV8825 | Red | Green | Blue | Black |

WARNING: Do not swap wire pairs arbitrarily. If the motor vibrates but does not turn, swap one entire coil (e.g., exchange Red and Green) to reverse the phase.

Standard bipolar 4-lead configuration:

Verified continuity: Red-Blue = Phase A, Black-White = Phase B.

The BJ42D15-26V10 is a NEMA 17 hybrid stepper motor manufactured by Hunan Keli Motor Co., Ltd.. It is commonly used as an OEM part for Creality 3D printers, typically powering the Y-axis.  Verified Technical Specifications  bj42d15 26v10 stepper motor datasheet verified

Based on manufacturer data and verified community testing, the technical parameters for the BJ42D15-26V10 (and its closely related variants like the -26V09) are as follows:  Step Angle: 1.8° (200 steps per revolution).

Rated Current: 0.84A. Note that while some generic online listings suggest 1.5A, manufacturer-direct data confirms 0.84A as the accurate rating for this specific series. Holding Torque: 2.86 kg·cm (approx. 0.28 N·m). Phase Resistance: Approximately 6.0 Ω. Input Voltage: Maximum 24V DC.

Dimensions: 42 x 42 x 34 mm (Standard NEMA 17 footprint with 34mm body length). Shaft Diameter: 5 mm.  Common Applications 

This motor is a standard component found in several Creality models, including the Ender 3 series and CR-10. It is specifically optimized for low noise and smooth operation in 3D printing environments.  Technical Usage Notes 

Vref Calibration: When setting the Vref for motor drivers (like A4988 or TMC2209), use the 0.84A rated current rather than higher generic NEMA 17 values to prevent overheating.
