A three phase four pole 50 Hz induction motor has a rotor resistance of 0.02 Ω/phase and stand-still reactance of 0.5 Ω/phase. Calculate the speed at which the maximum torque is developed.

1500 rpm
1525 rpm
1475 rpm
1440 rpm

ANSWER EXPLANATION DOWNLOAD EXAMIANS APP

Condition for maximum torque,
Sm = R2/X2
= 0.04
Ns = (120*f)/P
= (120*50)/4
= 1500 rpm
S = (Ns - Nr)/Ns
Nr = Ns(1 - Sm)
= 1500*(1 - 0.04)
= 1440 rpm

A DC shunt generator has an induced voltage of 220 V on open circuit. When the machine is on load the terminal voltage is 200 V. Find the load current if the field resistance is 100 Ω and armature resistance is 0.2 Ω.

98 A
104 A
96 A
102 A

ANSWER EXPLANATION DOWNLOAD EXAMIANS APP

Voltage equation for Dc shunt generator,
Eb = V + Ia*Ra
V = Ish*Rsh
Ish = 200/100
= 2 A
Eb = V + Ia*Ra
20 = Ia*Ra
Ia = 20/0.2
= 100 A
I = 100 - 2
= 98 A
