Answer Posted / 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

armature winding of dc machine produce alternating emf then it convert in to dc by using commutator.But only we consider armature resistance why don't we consider inductive reactane effect?
A 10 MVA, 66KV, 50Hz, Y-connected 3-phase alternator has synchronous reactance of 0.635 Ù. It is working at full load at 0.8 lagging p.f. condition. Find torque angle, neglect armature resistance.
