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 where slip is defined as
s = n ? nR/n
Where n = revolutions per second of rotating stator speed and nR = 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.
