{Q.1} A three-phase induction motor runs at almost 1198 revolutions per minute (rpm) at no load and 1112 rpm at full load when supplied from a 60-Hz, three-phase source. (a) How many poles does this motor have? (b) What is the slip in percent at full load? (C) What is the corresponding frequency of the rotor currents? (D) What is the corresponding speed of the rotor field with respect to the rotor and with respect to the stator?
