A single phase, 220-V, 50 Hz, 4-pole induction motor has the following circuit parameters: Stator resistance = 2.5 Ω Rotor resistance = 3.5 Ω Stator reactance = 1.2 Ω Rotor reactance = 1.1 Ω Magnetising reactance = 50 Ω The motor is running at a speed of 1430 rpm. The rotor parameters are referred to stator. The friction and windage loss is 6 W and the core loss is 16 W. Determine: i. input power ii. output torque iii. output power and iv. efficiency
