Q. Calculate the frequency of the rotor side of the IM if the value of slip is 0.34 and the supply frequency is 70 Hz.

(A) 23.8 hz
(B) 22.7 hz
(C) 24.5 hz
(D) 23.1 hz
Correct : Option (A)

Explanation: 
 the frequency of the rotor side is low as compared to supply frequency. the rotor frequency is slip×(supply frequency)=.34×70=23.8 hz.
