Bj42d15 26v10 Stepper Motor Datasheet 'link' 🌟 🎉

The is part of the Keli Motor BJ42D series. It is a hybrid stepping motor, meaning it combines permanent magnet and variable reluctance technologies to provide high torque, accurate positioning, and fine step angles. The "42" indicates a 42mm x 42mm frame size (NEMA 17), while the "26" usually indicates a specific winding, torque, or body length profile (approximately 26mm–34mm) optimized for specific printer applications. 2. Technical Specifications (Datasheet Summary)

| Parameter | Value | |------------------------|---------------------------| | Rated voltage | 26 V DC | | Winding resistance | 10 Ω ±10% | | Rated current (calculated) | 2.6 A (using I = V/R) | | Inductance (typical) | 4–8 mH (assumed) | | Insulation class | B (130°C) | | Dielectric strength | 500 V AC for 1 min |

Based on manufacturer data and community verification for the BJ42D15 series: 1.8° (200 steps per revolution). Rated Current: 0.84A per phase.

The torque available when the motor is already running at a constant velocity.

This four-wire bipolar winding arrangement enables the motor to be driven with higher torque compared to unipolar configurations.

When connecting to a driver, set the stepper driver current (Vref) to match the motor's rated current (0.84A - 1.0A) to prevent overheating.

BJ42D15-26V10 is a specific model of NEMA 17 stepper motor, widely recognized as a standard component in Creality 3D printers

Standard bipolar stepper:

There were five layers. The first four were the standard datasheet. The fifth was labeled .

The represents a solid, reliable choice for designers and hobbyists needing a dependable NEMA 17 motor. Its combination of a 1.8° step angle, decent holding torque, and smooth operation makes it a staple for 3D printing and precision motion tasks.
