Bj42d15 26v10 Stepper Motor Datasheet Verified Jun 2026
Inductance measured at 1 kHz is 27.8 mH. The electrical time constant (L/R) is: [ \tau_elec = \frac27.8 \text mH26.15 \Omega \approx 1.06 \text ms ] This relatively high time constant implies that microstepping drivers operating above 25 kHz PWM frequency are recommended for smooth current regulation.
Most entry-level stepper motors (like the common 42BYGH series) are rated for 3–5V at 1.5–2A. The is fundamentally different. bj42d15 26v10 stepper motor datasheet verified
The is a high-precision, 2-phase hybrid stepper motor primarily manufactured by Hunan Keli Motor Co. and commonly used in Creality 3D printers like the Ender 3 series . While often referred to as a "Creality 42-34 motor," the "BJ" prefix indicates its origin from Keli Motor. Technical Specifications Summary Inductance measured at 1 kHz is 27
~4.8V to 5V (though typically driven by 12V or 24V printer power supplies). Dimensions: 42mm x 42mm x 34mm. Shaft Diameter: 5mm. Reference for VREF Settings The is fundamentally different
