What is Electrical Power Distribution Overview about?
1) Given: Frequency (f) = 60 Hz No. of poles (p) = 4 Synchronous speed (Ns) = 120f/p = 120*60/4 = 1800 rpm 2) Given: Full load slip (s) = 5% = 0.05 Synchronous speed (Ns) = 1800 rpm Slip speed (Ns - Nr) = 0.05*Ns = 0.05*1800 = 90 rpm Rotor speed (Nr) = Ns - Slip speed = 1800 - 90 = 1710 rpm So, the synchronous speed is 1800 rpm and the rotor speed is 1710 rpm.
