Bj42d15 26v10 Stepper Motor Datasheet Exclusive

High holding torque allows for secure "fail-safe" positioning. 7. Driver Recommendations

To prevent overheating and skipped steps, the driver's reference voltage (Vref) must be set correctly. bj42d15 26v10 stepper motor datasheet exclusive

Note: There is common misinformation that these are 1.5A motors; however, verified data indicates they are rated for a lower current of 0.84A to 1.0A depending on the specific variant. NEMA 17 ( Note: There is common misinformation that these are 1

| Parameter | Value | Unit | | :--- | :--- | :--- | | | 24 – 36 | VDC (Input) | | Rated Current/Phase | 1.0 (or 1.2) | A | | Phase Resistance | ~2.4 to 3.6 | Ω | | Phase Inductance | ~4.5 to 6.0 | mH | | Holding Torque | ~0.28 to 0.34 | N·m | | | Step Angle | 1

| Parameter | Value / Rating | Notes / Source | | :--- | :--- | :--- | | | BJ42D15-26V10 | Part of the broader Keli BJ42D series. | | Phase | 2-Phase | Hybrid stepper motor with a bipolar winding configuration. | | Step Angle | 1.8° | Standard for most NEMA 17 sized motors, yielding 200 steps/revolution. | | Flange Size | 42mm x 42mm | Physical mounting pattern of the front flange. | | Motor Length (L) | 34mm | The length of the steel motor housing (excluding shaft). | | Rated Current (Max) | 0.8A to 1.5A | Varies by application. Official rating: 0.8A . Peak: 1.5A. | | Body Length Identifier | 15 | In the BJ42D series, "15" represents the 34mm stack length. | | Shaft Diameter | 5mm (Common) | Standard for NEMA 17 motors; check your pulley's set screw size. | | Weight | Approx. 220-250g | Typical for a 34mm length stepper motor. | | Typical Operating Voltage | 12V–24V | Often powered by 5V or 24V signals in systems like the TOOCA Laser L1. | | Temperature Rise (Winding) | 60.6°C | Measured under load; lower heat generation is a key feature. |

This 2-phase hybrid stepper motor utilizes a standard 42mm x 42mm faceplate (NEMA 17 frame size) paired with a 34mm body length (often classified as a 42-34 motor). It operates with a native , providing 200 full steps per revolution. Creality Ender 3 Stock Factory Vref - Gist - GitHub
