A 120-V (line-neutral) wye-connected 4-pole 60-Hz three-phase induction motor is operating at 100% of its 10-kW rated output shaft power at 5% slip. What is the frequency of the rotor electrical currents in Hz?
Homework Answers
VL = 120
P = 4
f = 60
PL = 100 kw
S = 5%
Frequency of rotar fr = S*f
fr = 5/100 * 60
= 0.05*60
fr = 3 Hz
