A 3-phase, 6-pole induction motor is supplied from a 3-phase, 400 V, 50 Hz supply. If it is operating at full-load with 0.04 slip, determine: (1) The speed of the revolving field relative to the stator structure. (ii) The frequency of the rotor currents. (in) The speed of the rotor mmf relative to the rotor structure. (iv) The speed of the rotor mmf relative to the stator structure. (1) The speed of the rotor mmf relative to the stator field distribution. (vi) Are the conditions right for the development of the net unidirectional torque?.. A single-phase induction motor draws a current of 0.6 A at 230 V and 0.6 lagging p.f. If it runs at a speed of 100 radian per second and develops an output torque of 0.25 Nm, find its output power and efficiency. 18 The main winding of a 110V, 60 Hz, 0.25 hp, single phase capacitor start motor carries a current of 6-ampere which lags behind the applied voltage by 42°. The starting winding carries a current of 4A which leads the voltage vector by 40°. Calculate (i) the total starting current and the power factor. (ii) the phase angle between the main winding current and starting winding current. A 3-phase, 6-pole induction motor is supplied from a 3-phase, 400 V, 50 Hz supply.
