A 37.3 kW 4 pole 50 Hz induction machine has a friction windage
torque of 22 N-m. the stator losses equal the rotor circuit loss.
Calculate:
The input power to the stator when delivering full-load output
at a speed of 1.440 rev/min [44000 W]
The gross input and stator output power when running at a speed
of 1560 rev/min. the stator losses are as in (a) and the windage
and friction torque is unchanged [291 N-m; 40300
W]
