Always adjust the potentiometer on your stepper driver to match the motor's 1.5A rating. Exceeding this current will cause overheating and potential motor failure.
This datasheet provides the essential technical specifications, wiring configurations, and performance characteristics for the BJ42D15-26V10. Technical Specifications
Like all hybrid steppers, the torque of the BJ42D15-26V10 decreases as RPM increases. To maximize high-speed performance, it is recommended to use a higher input voltage to the driver (e.g., 12V or 24V), as this helps overcome the motor's back EMF. bj42d15 26v10 stepper motor datasheet
Use flexible jaw couplers when connecting to lead screws to account for minor shaft misalignments. If you'd like more specific information, please tell me: Specific driver you are using (e.g., TMC2209, A4988) Voltage of your power supply Mechanical load details (e.g., weight of the axis)
Suitable for light-duty milling and laser engraving. Always adjust the potentiometer on your stepper driver
Used in pick-and-place machines and automated lab equipment.
Note: If the motor spins in the opposite direction of your software command, reversing the leads of a single phase (e.g., swapping Black and Green) will invert the rotation. Performance Characteristics If you'd like more specific information, please tell
The BJ42D15-26V10 is a high-precision, two-phase hybrid stepper motor widely utilized in CNC machinery, 3D printers, and medical instrumentation. This NEMA 17 motor is engineered for applications requiring high torque density and reliable positioning within a compact form factor.
The BJ42D15-26V10 typically features a 4-wire bipolar configuration. Understanding the wire pairings is critical to prevent damage to your stepper driver. Phase A: Black (A+) and Green (A-) Phase B: Red (B+) and Blue (B-)
With a standard 1.8-degree step angle, the motor provides 200 physical steps per revolution. When paired with a microstepping driver (such as an A4988 or TMC2209) at 1/16 or 1/32 step resolution, the motor achieves exceptionally smooth motion and high positional accuracy.
