The torque of a rotor in an induction motor under running condition is maximum________?
Aat the zero value of slip
Bat the value of the slip which makes rotor reactance per phase equal to the resistance per phase
Cat the value of the slip which makes the rotor reactance half of the rotor
Dat the unit value of slip
Correct answer
B. at the value of the slip which makes rotor reactance per phase equal to the resistance per phase
Explanation
The correct answer is at the value of the slip which makes rotor reactance per phase equal to the resistance per phase.
