BJ42D15-26V10 is a NEMA 17 hybrid stepper motor manufactured by Hunan Keli Motor Co., Ltd. and is most commonly found as original equipment in Creality 3D printers

In the world of precision motion control, the stepper motor is the unsung hero. Among the myriad of NEMA 17 and NEMA 23 frames flooding the market, a specific model has been generating quiet but significant buzz in niche engineering circles: the .

The BJ42D15-26V10 is a high-precision, two-phase hybrid stepper motor widely utilized in automated machinery and 3D printing. This exclusive guide provides the technical specifications, wiring configurations, and performance data required for successful system integration. Core Technical Specifications 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

If the motor spins in the opposite direction of your software command, simply swap the order of one phase (e.g., swap Red and Blue) to reverse the polarity. 5. Performance Characteristics Torque-to-Speed Ratio BJ42D15-26V10 is a NEMA 17 hybrid stepper motor

The is a high-torque, hybrid bipolar stepper motor. Part of the 42mm (NEMA 17) series, it is engineered for applications requiring high positional accuracy and a slim profile. The "26V10" suffix typically denotes a specific winding configuration optimized for 1.0A to 1.2A current ranges, making it highly compatible with common drivers like the A4988 or TMC2209. 2. Key Electrical Specifications

The BJ42D15 runs drastically cooler than standard high-current steppers. This makes it ideal for enclosed 3D printers or medical devices where thermal dissipation is a challenge. hybrid bipolar stepper motor.

Normal stepper motor operating temperature is up to 80–100°C (surface). Excessive heat suggests the current is too high or the Vref is set incorrectly . Using the 26V10 at the 1.5A peak for too long without cooling can degrade it.
