Answer / rkptl_bly

n=(120 x f)/ p ie 1000rpm

Answer / p

Since we know Ns = (120xf)/p
Ns=synchronous speed in r.p.m.
f=supply frequency in Hz
p=no. of poles

so
Ns= (120x50)/6
Ns=6000/6
Ns=1000rpm

Answer / sagar

1000rpm

Answer / ananth haritsa

Speed(n)= 120 X F (Frequency in Hz) / P ( Pole )

If the frequency is 50 Hz and the poles are 4

There fore Speed = 120 X 50 / 4

= 1500 RPM ( Revolution Per Minutes)
