AC Induction Motor Speed Calculator

Welcome to our electric motor RPM calculator! This page will allow you to calculate the motor speed of an AC induction motor using the supply frequency and the number of pole pairs within the motor. 
Motor speed is an essential parameter in electric motor design. As such, it should be considered carefully.

ExplanationAC induction motor speed depends on the supply frequency and the number of pole pairs. To regulate the speed of an AC induction motor, one must vary these two variables to achieve the desired speed. There are also other methods of speed regulation:
