Question: The torque transmitted to an induction motor is a function of the slip between the rotation of the stator field and the rotor speed s

The torque transmitted to an induction motor is a function of the slip between the rotation of the stator field and the rotor speed s where slip is defined as

s = n ? n_R/n

Where n = revolutions per second of rotating stator speed and n_R = rotor speed. Kirchhoff?s laws can be used to show that the torque (expressed in dimensionless form) and slip are related by

T = 15(s ?s²) / (1 ? s) (4s² ? 3s + 4)

Figure shows this function. Use a numerical method to determine the slip at which the maximum torque occurs.

T. 2 :10 s 6. 4
