Bj42d15 26v10 Stepper Motor Datasheet Exclusive [2021] Page

This exclusive guide breaks down the electrical specifications, mechanical dimensions, and performance curves of this specific NEMA 17 variant to help you integrate it perfectly into your next project. 1. Product Overview

This exposé interprets BJ42D15-26V10 as a compact NEMA‑17 style stepper with a 15 mm stack and electrical characteristics suited for chopper drivers at ~26 V and ~1.0 A/phase. For design‑critical work, obtain the manufacturer’s official datasheet to confirm exact torque curves, thermal limits, mechanical drawings, and connector pinouts — the single authoritative source for final integration.

Based on the specifications commonly found in high-quality 42mm stepper motors used by Creality (e.g., 42-40/42-34 variants), the BJ42D15-26V10 operates under the following electrical and mechanical parameters. Electrical Characteristics ~ 3.0V - 4.8V DC (Varies by driver) Rated Current/Phase 1.0A - 1.5A (Dependent on printer) Resistance/Phase ~ 2.4 - 3.5 Ω Inductance/Phase ~ 2.8 - 4.5 mH Insulation Class Class B (130°C) Mechanical Characteristics Step Angle 1.8° ± 5% Holding Torque ~ 0.4 - 0.5 N.m (40 - 50 N.cm) Frame Size 42 × 42mm (NEMA 17) Motor Length ~ 40mm - 42mm Shaft Diameter 5mm (D-Shape) Weight ~ 250 - 300g 3. Performance Analysis: Why Choose this Motor? Exceptional Torque-to-Size Ratio

While not officially bearing the NEMA 17 certification mark, the BJ42D15-26V10 adheres to the de facto NEMA 17 standard in every critical way. bj42d15 26v10 stepper motor datasheet exclusive

Specifications are based on OEM technical documentation and real-world verification. Always test within your specific application limits. This article is for informational purposes. The "exclusive" term denotes aggregated, verified data not commonly found on retail sites.

To find the RMS current for driver configuration (like TMC2209), divide the max rated current by 2the square root of 2 end-root

Combining data from the original equipment manufacturer (Keli Motor Group) and confirmed community documentation, here are the primary electrical and mechanical characteristics. Performance Analysis: Why Choose this Motor

belongs to the 42-34 frame classification, meaning it features standard NEMA 17 faceplate dimensions with a 34 mm body length. It is a 2-phase hybrid stepping motor optimized for precise motion control. Specification Value NEMA 17 (42 mm x 42 mm) Body Length Step Angle 1.8° (200 steps per full revolution) Rated Current 0.84 A per phase Holding Torque 0.4 N·m (approx. 2.86 kg·cm) Shaft Diameter 5 mm (D-Shape) Max Voltage 24V DC (Optimal operating standard) Phases 2-phase bipolar Understanding the Part Number

is a prominent example of this practice. It is widely used by Creality as an OEM component, serving as the stock X or Y-axis drive motor across popular machines like the Ender 3 series. Because official documentation for this specific suffix is rarely compiled into standard retail hardware catalogs, this guide serves as an exclusive datasheet and tuning manual. It consolidates hard-to-find physical parameters, electrical tolerances, and precise driver configuration steps. 1.
