Consider a 25-hp, 230-V three-phase, 60-Hz squirrel cage induction motor operating at rated voltage and ftequency. The rotor I2R loss at maximum torque is 9.0 times that at full-load torque, and the slip at full load torque is 0.028. Neglect stator resistance and rotational losses. Find the maximum torque in per unit of full load torque and the slip at which it takes place. Find the starting torque in per unit of full load torque.
