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 / biswajit sahoo

unless you are not mention rpm you can not predict no of
poles with voltage and frequency

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

We know that, in case if there is a faulty insulation,or sc, the current is bypassed to earth through the earth wire that has low resistance.Actually, what will happen to that current that flows through gnd?In that case,if we come in contact with that faulty appliance, wont that current flow through us as we form a closed path by standing in gnd?Is grounding a safety measure?
