I found this motor which I believed had interesting specs, but when I checked out the data sheet, the torque-speed graph was replaced by a torque-frequency graph! I do not know what it means. How does it intuitively translate to torque at a given speed?

Thank you so much!

  • $\begingroup$ The datasheet you linked list rotational speed (r/min) as the secondary value on the horizontal axis below frequency $\endgroup$

RPM of a stepper motor

Formula for calculating stepping motor speed.

$$RPM = \dfrac{a}{360} \cdot f_z \cdot 60$$

$RPM$ = Revolutions per minute.
$a$ = step angle
$f_z$ = pulse frequency in hertz
