What happens to the synchronous speed of the induction motor if the number of stator poles increases? Correct Answer It decreases

The synchronous speed of the induction motor decreases if the number of stator poles increases. Since the formula for synchronous speed is given by Ns = 120f/P, where Ns represents the synchronous speed, f represents the frequency and P is the number of poles. Therefore it can be clearly seen that, synchronous speed inversely proportional to the number of stator poles.
