Combining data from the original equipment manufacturer (Keli Motor Group) and confirmed community documentation, here are the primary electrical and mechanical characteristics.
High holding torque allows for secure "fail-safe" positioning. 7. Driver Recommendations This exposé interprets BJ42D15-26V10 as a compact NEMA‑17
: This suffix often denotes specific winding characteristics or factory-set voltage/current revisions. For example, while widely assumed to be 1.5 A, "26V" series motors are confirmed by manufacturer-reaching enthusiasts to actually be rated at 0.84 A . Practical Application & Safety
This paper presents a comprehensive datasheet-style technical summary for the BJ42D15-26V10 stepper motor, synthesizing expected specifications, electrical and mechanical characteristics, performance curves, control recommendations, mounting and handling guidelines, and application notes. Where exact vendor data is unavailable, typical values and testing procedures for motors of this class are given to enable design decisions, validation testing, and safe integration. For example, while widely assumed to be 1
| Parameter | Value | Condition / Note | | :--- | :--- | :--- | | | 2 | Bipolar | | Step Angle | 1.8° ± 5% | 200 steps/revolution | | Voltage Rating | 26 VDC | Nominal | | Current Rating (per phase) | 0.5 A (Rated) / 0.8 A (Max) | Based on 10Ω winding | | Phase Resistance | 10 Ω ± 10% @ 20°C | High resistance = high efficiency | | Phase Inductance | 12 mH ± 20% | Typical for 26V operation | | Insulation Class | B (130°C) | F-class available on custom order | | Dielectric Strength | 500 VAC / 1 minute | |
Because the phase resistance is 10Ω, you do not need current chopping for low speeds. You can drive this motor with a simple L298N H-bridge and a 24V PWM signal for ultra-low-noise applications. This is impossible with low-resistance 2A motors.
