The total rotor copper loss of a 3-phase, 208V (line-to-line), 60Hz, six-pole induction motor is 300W, with the rotor copper resistance = 0.1192 (per phase). The motor drives a mechanical load, and the torque (TL) required for the load varies approximately linearly with the speed that is given by: T₁ = 0.4@m+30 [Nm]. If the turns ratio between the stator and rotor windings is 1, determine the slip for the above condition, and the speed of the mechanical load.
