This Matlab based software compute the speed, output torque and power, stator current, power factor, and efficiency when an induction motor is operated at rated voltage and frequency.

The program is divided into the following parts:

• tpDin: This function performs the mathematical calculations. Use the following syntax to invoke the function:

function [na1, ns, Tflecha, Pflecha, I1, fp, nef] = tpDin(s, polos, fe, potencia, VLL, R1, R2, X1, X2, Xm)

• tpDinGrafico: Plot the values obtained with tpDin function.

• TpDinGUI: Presents the results in a user friendly graphical interface. It allows the modification of input parameters.

This program solves the Example 6.2 of the book Electric Machinery (Sixth Edition), from A. E. Fitzgerald.
