MATLAB program to compute the back EMF and armature current of a DC Motor

clc; clear all; P = input('Number of poles are: '); Phi = input('Flux per pole in Wb is: '); Z = input('Total number of armature conductors are: '); N = input('Armature speed in rpm is: '); V = input('Supply voltage in volts is: '); Ra = input('Armature resistance in Ohms is: '); W = input('1 for lap wining and 2 for wave winding: '); if W == 1 Eb = (Phi * N * Z) / 60; end if W == 2 Eb = (P * Phi * N * Z)/120; end Ia = (V - Eb)/ Ra; disp('Back EMF developed in the motor in volts is:'), Eb disp('Armature current in A is: '); Ia
