A balanced three-phase, 60-Hz voltage is applied to a three-phase, two-pole induction motor. Corresponding to a per-unit slip of 0.05, determine the following:
(a) The speed of the rotating-stator magnetic field relative to the stator winding.
(b) The speed of the rotor field relative to the rotor winding.
(c) The speed of the rotor field relative to the stator winding.
(d) The speed of the rotor field relative to the stator field.
(e) The frequency of the rotor currents.
(f) Neglecting stator resistance, leakage reactance, and all losses, if the stator-to-rotor turns ratio is 2:1 and the applied voltage is 100 V, find the rotor-induced emf at standstill and at 0.05 slip.
