Electric Motor Speed Control, Formula And Calculator

Then, Motor Speed Formula = (f *120)/p = 120*60 / 4 = 1800 RPM. So, the synchronous speed for this motor is 1800 RPM. Let's assume that the actual speed of the motor is 1750 RPM. To find the slip speed, we use the formula: Slip Speed=Synchronous Speed−Actual Motor. Slip Speed=1800−1750=50 RPM.
