Answer / ali raza

As we know that N=120f/p from here we can eisly suggest
here that moter pole depend on speed and frequincy not on
voltages there4 we can not suggest motor pole

Answer / uttam kumar sarkar

Motor pole dipenda upon Speed(N),Frequency(f).
Now we know the Syschronous Speed N=120f/P,
where P is No. of pole,
If synchronous Speed N=1500,
then P=120f/N, where,N=1500rpm,f=50.
P=(120*50)/1500
=4

So the No. of pole will be 4.

thanks to all
