A three-phase, 4-pole, 50 Hz induction motor runs at 1425 rpm. Find out the percentage slip of the induction motor.

5%
3%
4%
6%

ANSWER EXPLANATION DOWNLOAD EXAMIANS APP

Slip, s = (Ns - Nr)/Ns
Ns = 120f/P
Ns = 1500 rpm

s = (1500 - 1425)/1500
s = 0.05
%s = 5%

5 mH
5 H
0.2 H
0.2 mH

ANSWER EXPLANATION DOWNLOAD EXAMIANS APP

Here,
ω = 500 rad/sec = 2πf.
At Resonance condition,
ωL = 1/(ωC)
L 0.2 H
Also at series resonace
1. fr = 1/[2π√(LC)]
2. PF = 1
3. Maximum current
4. Source voltage = voltage across resistor.
