Question:

Consider the 460-V, 250-kW, four-pole induction motor and drive system of Problem 11.21.

a. Write a MATLAB script to plot the speed-torque characteristic of the motor at drive frequencies of 20, 40, and 60 Hz for speeds ranging from -200r/min to the synchronous speed at each frequency.

b. Determine the drive frequency required to maximize the starting torque and calculate the corresponding torque in N · m.
