Bj42d15 26v10: Stepper Motor Datasheet

The BJ42D15-26V10 is a NEMA 17 stepper motor manufactured by Keli Motor (often found in Creality 3D printers like the Ender 3). While a direct single-page datasheet for the "26V10" variant is elusive, its specifications are largely standardized across the BJ42D15 series. Core Specifications

The motor features a 4-wire bipolar configuration. While wire colors can vary between batches, standard Creality-style wiring often follows this order: : Pins 1 and 4 (often Red/Blue or Black/Green)

Critical Warning: Do not exceed 1.2A per phase. This motor is voltage-driven. Over-current will cause magnetic saturation and rapid overheating, demagnetizing the rotor.

like the Ender 3 series. While finding a single "official" PDF datasheet can be challenging, technical specifications can be synthesized from manufacturer data and user documentation. Funduinoshop Core Technical Specifications The following parameters are typical for the

• BJ42 – Manufacturer series (BJ Motor or compatible), 42 mm frame.
• D15 – Possibly stack length (15 mm rotor/stator length) → low holding torque.
• 26V10 – Rated voltage 26 V DC, winding resistance 10 Ω per phase (at 20°C).
