The step motor is moving at the fastest rate of frequency
The speed of the data is said to guarantee the speed at which the torque is rated. You're going to increase the frequency and you're going to increase the speed, but you're going to have a lower capacity of the load. The basic goal of stepping motor is not to make it idle, or to carry a load. It doesn't carry the load even if you have that high speed.
The formula for the speed of the ordinary motor is the same thing, it's n = 60f/P, and P is the logarithm.
Two phase stepper motor without segmentation is a revolution of the 200 pulse, stepper motor revolutions will happen too high locked-rotor, although in the case of without load can be transferred to more than 1000 revolutions per minute, but it actually has no real meaning, stepper motor is running is better under low number, general working condition is the best at 300 to 600 revolutions per minute. If you really want to know how fast it can go, then you have this formula for the number of turns = frequency / 200 * M (M is a fine fraction) anyway, we're doing 3, 000 revolutions per minute.
