Bj42d15 26v10 Stepper Motor Datasheet Exclusive [portable] Info

The is a NEMA 17 hybrid stepper motor manufactured by Hunan Keli Motor Co., Ltd. , commonly found in Creality 3D printers like the Ender-3 S1 series. Although official factory datasheets for this specific variant are rare, community testing and cross-referencing from manufacturers provide the following core specifications: Technical Specifications Manufacturer: Hunan Keli Motor Co., Ltd. Form Factor: NEMA 17 (42 x 42 mm) Length: 34 mm (standard for the "15" series) Step Angle: 1.8∘1.8 raised to the composed with power (200 steps per revolution)

( I_RMS = I_max \times 0.707 = 1.5A \times 0.707 \approx 1.06A )

Because the resistance is 26Ω per phase, at 1.0A, the power dissipation is: bj42d15 26v10 stepper motor datasheet exclusive

Most engineers see "0.12 Nm" and dismiss this motor. That is a mistake. This motor is not for holding a load; it is for dynamic movement at 26V.

When converting a printer to direct drive, a (e.g., the "Sherpa Mini" configuration) requires a longer 25mm shaft with a threaded end to accept a hobbed gear. This is not a standard part and must be ordered specially from Keli or modified with a shaft extension. Form Factor: NEMA 17 (42 x 42 mm)

💡 While the Class B insulation allows for high internal temperatures, attaching a passive heatsink to the motor body can extend the lifespan of the internal bearings.

: While specific to exact sub-models, similar 0.84 A Keli motors (like the JK42HS34-0844) show a resistance of ~5.75 Ωcap omega and an inductance of ~9.3 mH. Deciphering the Model Name

Because stack height is only 15mm, the rotor is light. This motor can accelerate from 0 to 3000 RPM in less than 15 milliseconds using a 24V driver with 32-microstep interpolation. It is perfect for the Z-axis or vacuum nozzle rotation in light pick-and-place machines.
