| 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. | | | Phase | 2-Phase | Hybrid stepper

BJ42D15-26V10 Stepper Motor Datasheet: The Ultimate Technical Blueprint

The is a specialized NEMA 17 stepper motor optimized for 24V–28V systems requiring moderate torque at low to medium speeds . Its 26Ω phase resistance and 1.0A current rating make it an energy-conscious choice for precision positioning, not brute force. When paired with a modern microstepping driver (e.g., TMC2209 at 26V, 1.0A), it delivers smooth, quiet motion for desktop automation, medical devices, and light industrial equipment.
