Bj42d15 26v10 Stepper Motor Datasheet Review
I cannot directly access or retrieve specific PDFs, proprietary datasheets, or real-time external documents, including the exact datasheet for a part number like (which appears to be a hybrid stepper motor, likely from a Chinese or OEM manufacturer such as BJX Motor, Changzhou, or similar).
These motors are Class B insulated, meaning they can safely handle internal temperatures up to 130∘C130 raised to the composed with power C , though a surface temperature below 60∘C60 raised to the composed with power C is ideal for longevity.
Set your stepper driver's Vref current limit to 1.0A (Or 0.7A RMS if using a TMC silent driver).
The is a widely utilized hybrid stepper motor in the automation and robotics industries. Manufactured primarily by Jinye (and rebranded by various distributors), this motor is part of the standard NEMA 17 frame size family. bj42d15 26v10 stepper motor datasheet
Operate this motor below 600 steps per second (300 RPM) for optimal performance.
The is a "current-limited" motor. If you connect it directly to a 12V battery (without a chopper driver), Ohm's Law dictates: I = V / R = 12V / 2.6Ω = 4.6 Amps . The motor will reach 130°C in under 60 seconds and be destroyed.
To avoid skipping steps or overheating your motor, you must correctly set the motor driver's reference voltage (VREF). In desktop 3D printers using drivers like the A4988 or TMC2208/TMC2209, setting the current to roughly balances cool operation with ample torque. BJ42D15-26V10 rated at a maximum current ( Imaxcap I sub max end-sub ) of 0.84A, the target driving current ( Iruncap I sub run end-sub ) should be: I cannot directly access or retrieve specific PDFs,
The standard nomenclature of the family defines its dimensional footprint and underlying electrical behaviors. The "42" denotes its 42mm x 42mm frame size, aligning perfectly with the standard NEMA 17 configuration. The "15" and subsequent "26V10" suffix denote specific internal winding revisions designed for low power consumption and high heat dissipation.
The is a widely utilized, high-efficiency NEMA 17 hybrid stepper motor manufactured by Keli Motor Group . It is prominently found as an OEM component in Creality 3D printers , powering linear motion axes like the X, Y, or Z-axis on popular machines. Understanding its internal datasheet parameters is critical for calculating driver reference voltages (VREF), ensuring cool operating temperatures, and avoiding skipped steps during long printing runs. Technical Specifications and Datasheet Overview
The BJ42D15 adheres strictly to the NEMA 17 mounting standard. While the faceplate is square, the electrical characteristics (26V/1.0A) make it unique. The is a widely utilized hybrid stepper motor
You may find this motor cross-referenced as a 42-34 motor in Creality's official documentation .
For standard A4988 or TMC2208/2225 drivers on Creality boards, a Vref of roughly 0.58V to 0.6V is often recommended to target ~0.8A current safely.
