The RMS values of referred rotor current I 2 / , and exciting current I e , d. The 3-phase values of the air-gap power P g , the stator copper loss P cus , the rotor copper loss P cur , the gross output power P m and the slip s, e. The operating shaft speed r in mech. rad/s and the electromechanical torque (gross) T e in Nm. Calculate the efficiency by assuming that rotational losses are 2335 W at the speed in (e)....
