Recommended for "Silent Step" applications where noise reduction is a priority.
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. bj42d15 26v10 stepper motor datasheet verified
The "42-34" label often found on the back of these motors indicates the frame width (42mm) and the motor body length (34mm) [9]. The "BJ" prefix indicates the manufacturer (typically or a similar high-volume OEM for Creality). bj42d15 26v10 stepper motor datasheet verified
