For standard A4988 or TMC2208/2225 drivers on Creality boards, a Vref of roughly 0.58V to 0.6V is often recommended to target ~0.8A current safely.

. It is widely used as a stock component in Creality 3D printers, such as the Ender 3 and CR-10 series, typically serving as the Y-axis motor Technical Specifications bj42d15 26v10 stepper motor datasheet

Alternative common standard: Black/Green (A) and Red/Blue (B) – always verify continuity with a multimeter.

This technical guide compiles data across manufacturer specifications, community testing databases, and firmware repositories to present an accurate, actionable datasheet for engineers and makers. Core Technical Specifications VREF=Imax×8×Rsense×0

Approximately 0.35 Nm to 0.42 Nm (50-60 oz-in) Detent Torque: ~15 mNm Rotor Inertia: ~35 g·cm² Weight: ~250g to 300g Pinout and Wiring Configuration

Operating at 24V allows for better torque at higher speeds compared to 12V. This document is a simulated technical analysis

Typical applications: 3D printers, small CNC machines, medical pumps, office automation.

This document is a simulated technical analysis. Actual values may differ. Always refer to the original manufacturer’s datasheet before design or integration.

: This is usually given in Amps per phase. For example, if it's 1A/phase, you would need to ensure your driver can supply this current.

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.
