# What does the Torque vs Frequency plot mean for a stepper motor

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!

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

$$RPM = \dfrac{a}{360} \cdot f_z \cdot 60$$
$$RPM$$ = Revolutions per minute.
$$a$$ = step angle
$$f_z$$ = pulse frequency in hertz
