The document provides calculations to design the rotor for a 15 kW, 3-phase, 6-pole, 50 Hz induction motor. It determines that the rotor should have 39 slots with each copper bar having a cross-sectional area of 98.9 mm2. The end ring current is calculated to be 1022.6 A, requiring an end ring area of 204.5 mm2. The total copper loss in the rotor bars is estimated to be 241 W. Key motor parameters like air gap length, rotor diameter and peripheral velocity are also confirmed.
