A three phase Y-connected 220-Volt 10-Hp, 60Hz, 6-pole induction motor has the following constants in Ohms per phase referred to the stator.

R1=0.294, R2=0.144, X1=0.503, X2=0.209, Xm=13.25. The total friction and core losses may be assumed to be constant at 403 Watts, independent of load. For a slip of 2% , compute the speed, output torque, and power and stator current, power factor and efficiency when the motor is operated at rated voltage and frequency.
