    3 Phase Motor Speed Control Methods Your Electrical Guide

    The speed of a three phase induction motor is given by n n s 1s and n s 120fp this shows the speed of three phase induction motor depends upon synchronous speed n s and slipsthe synchronous speed of induction motor depends upon supply frequency and the number of stator poles so by changing the supply frequency the number of stator poles and slip we can change the speed of 3

    Threephase Synchronous Motor Construction Working

    A threephase synchronous motor has no starting torque it has to be brought up to speed or as close to it as possible by some other means so that it can pull itself into synchronism once up to speed the rotor field can be excited with direct current and the rotor is in effect then dragged around at the same speed as the threephase stator
