Bj42d15 26v10 Stepper Motor Datasheet -

If you want, I can:

The BJ42D15-26V10 is a NEMA 17 hybrid stepper motor commonly found as original equipment in Creality 3D printers, such as the Ender-3 series. Often referred to by its dimensions as a "42-34" motor, it is frequently used to drive the X, Y, or Z axes. Core Technical Specifications BJ42D15-26V10

is a 2-phase bipolar stepper motor designed for precise motion control. Creality Ender 3 Stock Factory Vref · GitHub bj42d15 26v10 stepper motor datasheet

Important Context: "BJ42D15" is almost certainly a generic designation used by Chinese manufacturers (often found on Alibaba, AliExpress, or integrated into CNC/3D printer kits). It typically breaks down as:

Because there is no single global manufacturer (like NEMA or Oriental Motor) for this specific part number, official PDF datasheets don't exist in the traditional sense. However, based on the electrical physics of a 42mm, 15mm length motor, here is the definitive technical guide and equivalent datasheet for this motor. If you want, I can:

If the manufacturer's original datasheet is not available at the distributor (e.g., Mouser, DigiKey), use these strategies:

Because this is a low-voltage, low-inductance motor, it must be driven by a Chopper Driver (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 BJ42D15-26V10 is a NEMA 17 hybrid stepper

Suitable Drivers:

Voltage Settings: While the motor is rated for ~2.6V, chopper drivers typically supply 12V, 24V, or 36V to the driver board. The driver chops the voltage to maintain the set current limit (1.5A).
