Determine the correctness or otherwise of the following assertion[A] and the reason[R] Assertion [A]: Under V/f control of induction motor, the maximum value of the developed torque remains constant over a wide range of speed in the sub- synchronous region. Reason [R] The magnetic flux is maintained almost constant at the rated value by keeping the ration V/f constant over the considered speed range. (A) Both [A] and [R] are true and [R] is the correct reason for [A] (B) Both [A] and [R] are true and but [R] is not the correct reason for [A] (C) Both [A] and [R] are false (D) [A] is true but [R] is false Determine the correctness or otherwise of the following assertion[A] and the reason[R] Assertion [A]: Under V/f control of induction motor, the maximum value of the developed torque remains constant over a wide range of speed in the sub- synchronous region.
