What is the relation between the Peripheral speed(N) , no.of poles(P) and diameter(D) of a cylindri..

Answer / masoom raza

n=120f/p
from this we can say that n is inversely proportional to number of poles.

but n is independent of motor(it doesn't matter weather a motor is large or small)

itz because for bigger diameter rotor higher speed is nor
possible as it experiences greater centrifugal force.
