Q. A three-phase, 60-Hz induction motor runs at almost 1800 r/min at no load, and at 1710 r/min at full load.
(a) How many poles does the motor have?
(b) What is the per-unit slip at full load?
(c) What is the frequency of rotor voltages at full load?
(d) At full load, find the speed of (i) the rotor field with respect to the rotor, (ii) the rotor field with respect to the stator, and (iii) the rotor field with respect to the stator field.
