Bj42d15 26v10 Stepper Motor Datasheet Verified Jun 2026

This article provides a of the BJ42D15-26V10, detailing its specifications, operating principles, and typical applications to assist engineers and hobbyists alike. What is the BJ42D15-26V10?

This motor is a "short" NEMA 17 (34mm length) designed to balance weight and torque. In Creality machines, it is often paired with an TMC2208/2209

After cross-referencing multiple manufacturer pages—from the Romanian KELI distributors to the Russian 3D printing forums—the following verified data applies to the . bj42d15 26v10 stepper motor datasheet verified

: 5mm diameter, typically a "D-shape" for secure pulley mounting. Wiring and Pinout The motor is a 2-phase bipolar

Based on standardized component data and commonly used variants in the Ender series printers, here are the verified specifications: 1. Electrical Characteristics This article provides a of the BJ42D15-26V10, detailing

Works with standard A4988 or TMC2208/TMC2209 drivers found in most 3D printer mainboards. Creality Ender 3 Stock Factory Vref · GitHub

The BJ42D15-Y1W01E model (likely a different variant) shows: Bipolar, 53mm length, 1.4Ω resistance, 1.4mH inductance, 1.5A rated current. In Creality machines, it is often paired with

When using TMC2208, TMC2209, or similar Trinamic drivers, the Vref should be set based on the motor's rated current.

Due to its balanced torque and power consumption profile, the is optimal for:

After complete verification, the stepper motor stands out as a specialized, yet versatile actuator. It is not a high-torque monster—you would not use it to mill steel. However, it is a master of precision, low heat, and high-speed reliability .
