If you have landed on this page, you are likely searching for the elusive, exclusive datasheet for the BJ42D15 26V10. Standard datasheets are often dry, incomplete, or buried behind login walls. This article serves as your exclusive, deep-dive technical resource. We will dissect every line of the datasheet, explore real-world performance metrics, compare it to competitors, and provide application notes you won’t find in the official documentation. bj42d15 26v10 stepper motor datasheet exclusive
The BJ42D15-26V10 belongs to the NEMA 17 frame size category, known for balancing high torque with a compact footprint. 1.8° (200 steps per revolution) Rated Voltage: 3.6V DC Rated Current: 1.5A per phase Phase Resistance: 2.4 Ω ± 10% Phase Inductance: 3.7 mH ± 20% Holding Torque: 420 mN.m (min) Detent Torque: 15 mN.m (max) Rotor Inertia: 57 g.cm² Weight: 280g Physical Dimensions and Mounting
Since the official manufacturer datasheet is not publicly released in full (held as proprietary by Creality), the safest replacements are . If you need further assistance with this motor,
Total maximum dissipation (both phases active) = 52 Watts. Given the 220g mass and surface area, the motor will reach a steady-state temperature of approximately after 30 minutes of continuous operation at 26VDC. This is within Class B limits (130°C total), but heatsinking is advised for 24/7 operation.
Here is the exclusive "Golden Configuration" for this motor: Standard datasheets are often dry, incomplete, or buried
For more detailed information on the BJ42D15-26V10 stepper motor, please refer to the official datasheet provided by the manufacturer. Additionally, you can consult with technical experts or online forums to explore application-specific use cases and design considerations.
The motor conforms to standard NEMA 17 mounting specifications:
Before we look at graphs and winding diagrams, let’s break down the model number. Understanding this nomenclature allows you to spec the motor without the datasheet at hand.
