Show transcribed image text A three phase, 60 Hz, 10-hp (1 hp=746 W), 6-pole, 440-V, delta-connected induction motor is designed to operate at 3% slip on full load. The rotational plus stray losses equal 4% of the output power. When the motor operates at full load and rated voltage calculate; a. The rotor copper loss b. The air-gap power c. The power developed (converted) d. The shaft torque.
