Bj42d15 26v10 Stepper Motor Datasheet Exclusive ✦ Proven

Based on the series standards from the Keli Motor Group and community data on the GitHub Creality Vref database , the motor follows these parameters: Type: 2-Phase Hybrid Stepper Motor. Step Angle: 1.8∘1.8 raised to the composed with power (200 steps per revolution). Rated Current: Approximately 0.84A .

The speed-torque curve indicates that the motor maintains at least when driven at 24V.

This motor uses a standard 4-wire bipolar configuration. In most BJ-series motors, the wiring follows this color code (though you should always verify with a multimeter): Red (A+) & Blue (A-) Phase B: Green (B+) & Black (B-)
