belongs to the 42-34 frame configuration family. This designation signifies a standard 42mm x 42mm faceplate profile paired with a compact 34mm body depth. Creality Ender 3 Stock Factory Vref - GitHub Gist
| Parameter | Value | Unit | | :--- | :--- | :--- | | | 24 – 36 | VDC (Input) | | Rated Current/Phase | 1.0 (or 1.2) | A | | Phase Resistance | ~2.4 to 3.6 | Ω | | Phase Inductance | ~4.5 to 6.0 | mH | | Holding Torque | ~0.28 to 0.34 | N·m |
💡 To prevent overheating, ensure your stepper driver's Vref is tuned to deliver no more than 1.5A. For high-speed applications, use a 24V power supply to overcome back-EMF. bj42d15 26v10 stepper motor datasheet exclusive
Given it's a stepper:
(e.g., Ender 3, CR-10 series). Despite its ubiquity, official manufacturer datasheets are often restricted to OEM partners, making technical specifications difficult to source for end-users. Technical Specifications belongs to the 42-34 frame configuration family
The 26V rating allows operation from two 12V lithium battery packs in series (24-26V). The 0.5A current draw preserves battery life compared to 1.5A motors. The smooth torque at low speeds (1-5 RPM) ensures consistent fluid delivery.
A common misconception in internet forums is that these motors are built to safely pull up to For high-speed applications, use a 24V power supply
The 1.8° step angle provides 200 full steps per revolution. Combined with microstepping drivers (e.g., TMC2209), this motor allows for smooth, quiet, and incredibly detailed 3D printing, mitigating the "salmon skin" effect. Thermal Efficiency
