Find the total input power, Electrical Engineering

Assignment Help:

Q. A 230-Vdc shuntmotor delivers 30 hp at the shaft at 1120 r/min. If the motor has an efficiency of 87% at this load, find:

(a) The total input power.

(b) The line current.

(c) If the torque lost due to friction and windage is 7% of the shaft torque, calculate the developed torque.
