A four-pole, three-phase inductionmotor is energized from a 60-Hz supply. It is running at a load condition for which the slip is 0.03. Determine:
(a) The rotor speed in r/min.
(b) The rotor current frequency in Hz.
(c) The speed of the rotor rotatingmagnetic field with respect to the stator frame in r/min.
(d) The speed of the rotor rotatingmagnetic field with respect to the stator rotating magnetic field in r/min.
