### How to Determine the RPM on Stepper Motors | Sciencing

24 Apr 2017 ... Calculate the RPM for a motor that is driven at 500 electrical pulses per second. The answer is (500 pulses / second)(1 rev / 200 pulses)(60 seconds / minute) = 150 RPM. Calculate the RPM for a motor that has a 15-degree stepper angle and takes 24 steps to perform one revolution. If the motor is driven ...
