Bj42d15 26v10 Stepper Motor Datasheet Here

The 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

Perfect for direct-drive or Bowden setups where excess weight on the gantry must be avoided. Laser Engravers: Drives the X and Y axes smoothly.

"Day 43: Built the bj42d15 with graphene windings and a beryllium-copper rotor. Applied 26.10 kHz square wave via the Ψ-configuration. The rotor didn’t move. Instead, the air around it grew cold. My watch ran backward for 11 seconds."

The BJ42D15-26V10 is manufactured by KELI, a leading Chinese motor manufacturer specializing in micro and special motors. The "BJ" prefix designates a hybrid stepping motor, while "42D" refers to the frame size (42mm), which conforms to the NEMA 17 international standard (42×42mm mounting square). This standard ensures the motor is mechanically compatible with a vast ecosystem of brackets, pulleys, and lead screws. The "15" in the model number typically denotes a body length of approximately 34mm, while the suffix "26V10" likely indicates a specific winding variant with a rated current of 0.8A and a DC voltage rating of 26V. Designed as a 2-phase, bipolar stepper motor, it features a step angle of 1.8°, making it one of the most common types for precise positioning tasks. bj42d15 26v10 stepper motor datasheet

Note on Voltage: While the rated voltage is 2.6V, stepper motors are intended to be driven by constant-current chopper drivers (like the A4988 or TMC2209) supplied with much higher bus voltages (12V to 24V DC). The driver limits the current to the specified 1.0A, allowing the motor to achieve higher speeds without impedance choke. Wiring Diagram and Pinout
