clear ; clc ; close ; // Clear the work space and console
// GIVEN DATA
f = 50; // Frequency of the 2-pole Induction Motor
p = 2; // Total Number of Poles
// CALCULATIONS
Ns = (120*f)/p; // Synchronous Speed in RPM
Ns5 = -(120*f)/(5*p); // Synchronous Speed of 5th order space harmonic in RPM
N5 = -(120*5*f)/p; // Synchronous Speed of 5th order time harmonic in RPM
Ns7 = (120*f)/(7*p); // Synchronous Speed of 7th order space harmonic in RPM
N7 = (120*7*f)/p; // Synchronous Speed of 7th order time harmonic in RPM
// DISPLAY RESULTS
