Bj42d15 26v10 Stepper | Motor Datasheet

Because this is a low-voltage, low-inductance motor, it must be driven by a (current-limiting driver). Connecting it directly to a constant DC voltage source equal to its rated voltage (without current limiting) will damage the motor.

The motor features a 4-wire bipolar configuration. While wire colors can vary between batches, standard Creality-style wiring often follows this order: : Pins 1 and 4 (often Red/Blue or Black/Green)

However, official guidance from Creality for the Ender 3 series advises a Vref of approximately 1.06V for the 26V10 variant, which is nearly triple the calculated value above. This suggests that in many 3D printer applications, the motor is intentionally to increase torque, which correspondingly increases heat generation. Therefore, when installing this motor as a replacement, always verify the optimal Vref from your original printer’s manufacturer to balance torque and thermal performance. bj42d15 26v10 stepper motor datasheet

The BJ42D15 26V10 stepper motor is suitable for a wide range of applications, including:
