about the contour plots

Hello,

I want to create a contour map in order to obtain MTPA Control for Interior permanent magnet synchronous motor. I have attached the required contour map here. I could generate circle and ellipse but constant torque line i could not generate. Can somebody please help me how to obtain those lines in contour maps.

Thanking you in advance,

Waiting for help

Regards, Prashanth

To plot the constant torque contours and also other constraint curves of a PMSM, please refer to the following link.

PMSM Constraint Curves and Their Application - MATLAB & Simulink Example - MathWorks India

This page explains about the fundamentals of the curves, and also gives the commands required to plot the curves, for a given speed and torque.
