2) A 3f induction motor has a starting torque of 1.75 pu and a maximum torque of 2.5 pu when operated from rated voltage and frequency. The full-load torque is considered as 1 pu of torque. Neglect stator resistance. (a) Determine the slip at maximum torque. (b) Determine the slip at full-load torque. (c) Determine the rotor current at starting in per unit - consider the full-load rotor current as 1 pu. (d) Determine the rotor current at maximum torque in per unit of full- load rotor current.
