Bj42d15 - 26v10 Stepper Motor Datasheet

Suitable for light-duty milling and laser engraving.

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-)

Use flexible jaw couplers when connecting to lead screws to account for minor shaft misalignments.

Under continuous 1.5A load, the motor body can become hot to the touch. This is normal for Class B insulation; however, ensuring adequate airflow or using the motor's aluminum mounting as a heat sink will extend the lifespan of the internal bearings. Recommended Applications

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 Suitable for light-duty milling and laser engraving

Used in pick-and-place machines and automated lab equipment.

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. Phase A: Black (A+) and Green (A-) Phase

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.
