Bj42d15 26v10 Stepper Motor Datasheet Exclusive Hot! Jun 2026

At 26V and 1.0A continuous, the motor’s surface temperature stabilizes at approximately 65°C – 75°C (ambient 25°C) without active cooling. This is within safe limits for Class B insulation (130°C).

: While some generic 42-34 motors are rated at 1.5A, the BJ42D15 series used by Creality is specifically tuned for lower current (~0.84A) to maintain thermal stability. Holding Torque : Approximately 2.86 kg·cm (0.28 N·m). Dimensions : 42 x 42 x 34 mm (Standard NEMA 17 "42-34" frame). Shaft Diameter Input Voltage : Maximum 24V DC. Operational Features Stepper Motor Basics

The is a highly reliable NEMA 17 hybrid stepper motor manufactured by ⁠Keli Motor Group and heavily used across the ⁠Creality Ender 3 ecosystem . Finding its exact manufacturer technical parameters online is famously difficult, as most community documentation blends it together with similar 42-34 frame variants. bj42d15 26v10 stepper motor datasheet exclusive

This exclusive datasheet and integration guide uncovers the critical electrical, physical, and torque parameters needed to calculate exact driver reference voltages ( VREFcap V sub REF end-sub ) and safely optimize your motion control systems. Core Technical Specifications

To prevent overheating and skipped steps, the driver's reference voltage (Vref) must be set correctly. At 26V and 1

To get the most out of the BJ42D15-26V10, we recommend the following drivers:

The popularity of "BJ42" series motors has led to a flood of counterfeit units labeled BJ42D15 but with 4Ω windings (designed for 5V). These fakes burn out instantly at 26V. Holding Torque : Approximately 2

BJ42D15-26V10 is a high-precision NEMA 17 stepper motor frequently utilized in 3D printers, specifically as a replacement part for Creality machines like the Ender-3 S1, Ender-5 S1, and V3 series. Technical Specifications
