Answer d and e
A three-phase, 230 v, 30 hp, 60 Hz, six-pole induction motor is operating with a shaft load that requires 21.3 kW to cross the air gap to the rotor. Rotor copper loss is 1.05 kW, and mechanical and stray load losses are 300 W. Determine: shaft speed; mechanical power developed; developed torque; shaft torque; and, percent of rated hp the machine is required to deliver to the load. a. b. C. d. e.
