To find the RMS current for driver configuration (like TMC2209), divide the max rated current by 2the square root of 2 end-root
The BJ42D15 26V10 stepper motor offers several features that make it suitable for a range of applications: This datasheet analysis settles the confusion by delivering
Because stack height is only 15mm, the rotor is light. This motor can accelerate from 0 to 3000 RPM in less than 15 milliseconds using a 24V driver with 32-microstep interpolation. It is perfect for the Z-axis or vacuum nozzle rotation in light pick-and-place machines.
While some online communities erroneously assume these motors can handle 1.5 Amps, official specifications for the BJ42 series indicate a much lower rated current of It is perfect for the Z-axis or vacuum
The 0.8A to 1.5A current capability of this motor dictates which stepper drivers are appropriate.
