I'm unable to identify where my code below is wrong as it is not giving the right shape of the curve required .The question is : Write a Matlab program to Plot Rotor resistance (R) vs. starting torque (Ts). Assume Ns=25 r.p.s, X=0.7 ohm, E=80 V.

I'm unable to identify where my code below is wrong as it is not giving the right shape of the curve required .The question is : Write a Matlab program to Plot Rotor resistance (R) vs. starting torque (Ts). Assume Ns=25 r.p.s, X=0.7 ohm, E=80 V. Take the range of R2 from 0 to 1.5 ohm. Make sure you take enough points to make the figure smooth. where Ts=3*E^2*R/(2*pi*Ns*(R^2+x^2)).

my solution is:

E=80; R=0:.1:1.5; x=0.7; Ns=25; Ts=3*E^2*R/(2*pi*Ns*(R^2+x^2)) plot(R,Ts) ylabel('torque') xlabel('rotor resistance') grid on
