Obtain an expression for the condition of maximum torque of an induction motor. Sketch the torque- slip curves for several values of rotor circuit resistance and indicate the condition for maximum torque to be obtained at starting. If the motor has a rotor resistance of 0.02 2 and a standstill reactance of 0.1 92, what must be the value of the total resistance of a starter for the rotor circuit for maximum torque to be exerted at starting ?
