A 120 HP 4-pole 60 Hz induction machine has a friction and windage torque of 18 N-m. The stator-losses are equal the rotor circuit loss. Calculate: (i) The synchronous speed and slip when running at 1200 rpm. (ii) The input power to the stator when delivering full-load output at a speed of 126 rad/s.
