Bj42d15 26v10 Stepper Motor Datasheet May 2026

Ideal for X, Y, and E (extruder) axes due to its balance of weight and torque.

For quiet operation, use a driver with StealthChop technology.

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.
