+//INPUT DATA
+VL=11000;//Supply line voltage in V
+P=12;//Number of poles
+f=50;//Supply frequency in Hz
+R2=0.2;//Rotor resistance in ohm
+X2=1.2;//Rotor reactance at stand still in ohm
+N=480;//Full load speed in rpm
+
+//CALCULATIONS
+s=(R2/X2);//Slip at maximum torque
+Ns=(120*f)/P;//Synchronous speed in rpm
+s1=(Ns-N)/Ns;//Slip at full load
+T=((R2^2+(s1^2*X2^2))/((2*X2)*(s1*R2)));//Ratio of maximum and full load torque
+T1=((R2^2+X2^2)/(2*X2*R2));//Ratio of maximum and starting torque
+
+//OUTPUT
