The "26V10" suffix on the model number indicates that this motor is rated for . An earlier table provided by ELEGOO explicitly identifies the BJ42D15-26VXX as an 0.8A motor. Furthermore, in an official Creality support document for the Ender 3 series, the "26V10" motor’s rated current is listed as 1.5A , and the recommended Vref for the TMC2208 driver is 1.06V. This difference is because 0.8A refers to the phase RMS current at the motor’s base-rated voltage, whereas 1.5A is the peak current limit required for microstepping drivers to deliver full torque. For safe operation, always set the driver’s current limit using the latter value.
Approximately 0.28 N·m to 0.32 N·m (28-32 N·cm) Detent Torque: 120 g·cm Rotor Inertia: 38 g·cm² Insulation Class: Class B ( 130∘C130 raised to the composed with power C
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.
The internal structure is optimized for reduced vibration, resulting in quieter operation, crucial for home 3D printing environments.

BJ42D15-26V10 Stepper Motor Datasheet: A Comprehensive Guide
Before spinning the motor, adjust the current limit potentiometer on your driver board. Over-driving the motor will cause permanent thermal damage, while under-driving will result in skipped steps.
The is a specific NEMA 17 stepper motor model, frequently used in 3D printers like the Creality Ender 3 and CR-10 series. While a single official "datasheet" document can be elusive online, its core specifications are widely documented through its use in consumer electronics. Key Technical Specifications Step Angle: 1.8 degrees (200 steps per full revolution). Frame Size: NEMA 17 (42mm x 42mm faceplate). Rated Current: Typically 0.84A to 1.0A per phase. The "26V10" suffix on the model number indicates
"Day 47: Placed a live mouse in a Faraday cage 10cm from the motor. Ran the sequence for 3 seconds. The mouse appeared on the other side of the lab, inside a sealed glass jar. Alive. Unharmed. The jar was manufactured in 2029. Today is 2026."
: Measured in mH, this is another critical parameter for designing with stepper motors.
The is a NEMA 17 stepper motor commonly found in Creality 3D printers, such as the Ender 3 series. While specific manufacturer-direct datasheets for the "V10" variant are rare, community data and specifications for very similar "V" models (like the V09 and V50) clarify its core performance characteristics. Core Specifications Model: BJ42D15-26V10 Frame Size: NEMA 17 (42 x 42 mm) Motor Height: 34 mm (standard "42-34" class) Step Angle: 1.8° (200 steps per revolution) Rated Current: ~0.84 A per phase
While official standalone PDF documentation can be notoriously difficult to find for specific OEM batch numbers, community testing, manufacturer correspondence, and cross-references from the Keli Motor Group establish the standard datasheet metrics for the BJ42D15-26V10 variant: Specification Profile NEMA 17 (42 mm × 42 mm) Body Length 34 mm (Often referred to as a "42-34" motor) Step Angle 1.8° (±5% accuracy per full step) Steps Per Revolution Phase / Configuration 2-Phase Hybrid / Bipolar Rated Voltage Maximum 24V – 26V DC Rated Current (Peak) 0.84A – 1.0A max Holding Torque ~2.86 kg·cm (0.28 N·m / 40 oz-in) Shaft Diameter & Style 5mm "D-Shape" or Round (varies by production lot) Insulation Class Class B (Safe operating temperature up to 80°C rise) Understanding the Part Number (Decoded) This difference is because 0
