Bj42d15 26v10 | Stepper Motor Datasheet =link=

Typically, the KELI BJ42D series offers performance curves similar to other NEMA 17 motors. A typical curve shows torque decreasing as speed (PPS) increases. For example, a comparable model, BJ425D5-TW01, operates at 24V with a current of 0.4A to 1.8A, generating torque that declines as speed increases. Therefore, the actual torque produced by the BJ42D15-26V10 will depend on the chosen driver and operating voltage.

The is a high-precision, NEMA 17-sized hybrid bipolar stepper motor commonly used in 3D printers, CNC machines, and medical equipment . Produced by manufacturers like Beijing Motor, this specific model is favored for its reliable torque output and compatibility with standard stepper drivers. Typically, the KELI BJ42D series offers performance curves

The BJ42D15-26V10 motor is a standardized NEMA 17 component, ensuring compatibility with a vast ecosystem of 3D printer and laser engraver parts.

In 3D printers and CNC machines, the motor driver (like TMC2208, A4988, or DRV8825) regulates current using a reference voltage (Vref). The formula for TMC2208 in UART mode may differ, but for legacy standalone drivers, the formula is:

The BJ42D15 26V10 stepper motor datasheet provides the following key specifications: Therefore, the actual torque produced by the BJ42D15-26V10

The BJ42D15-26V10 has a (excluding the shaft). The total length including the shaft extension is typically 48mm. Key mechanical dimensions from a generic BJ42D15 series drawing include a 42mm frame, 5mm diameter shaft, 22mm shaft length, and 31mm distance between mounting holes. The motor complies with the NEMA 17 standard, making it a direct fit for standard 31mm spaced mounting holes.

The "BJ42D15-26V10" code is an internal manufacturer designation where the segments generally represent physical and electrical attributes:

The is a two-phase, 1.8-degree hybrid stepper motor. The "42" in the name typically refers to the 42mm

Note: If the motor spins in the opposite direction of your software command, reversing the leads of a single phase (e.g., swapping Black and Green) will invert the rotation. Performance Characteristics
