It gives you the speed of response.....settling time is the inverse of the product damping ratioXnatural frequency...damping ratio is decided from overshoot specifications and settling time therefore is controlled by natural frequency.....

An 8 pole, 50 Hz, 3-phase IM is loaded to a poing where pull out torque will occur. The rotor resistance per phase is 0.3 ohm and motor stalls at 650 rpm. The slip when motor stalls is A 1 B 0 C 13.33% D 10.33%
