5. A 5 hp, 220 V, 60 Hz, four-pole three-phase induction motor operatesat 1740 r/min when fully loaded at its rated voltage and rated frequency. The motor parameters are Rs-0.2950, Rr=0.3790, Xm-22.2430,and X₁ X₁-0.6760. Please calculate: the slip, stator current, rotor current, and developedtorque when running at rated conditions.
