Question: a determine the speed of the motor at maximum torque...
(a) Determine the speed of the motor at maximum torque.
(b)Determine the starting torque in per unit. (Full-load torque is one per- unit torque.)
(c) Determine the value of resistance to be added to each phase of the rotor circuit so that maximum torque is developed at the starting condition
(d)Determine the speed at full-load torque with the added rotor resistance of part (c)
