//Problem 38.06: The core of a transformer operating at 50 Hz has an eddy current loss of 100 W/m3 and the core laminations have a thickness of 0.50 mm. The core is redesigned so as to operate with the same eddy current loss but at a different voltage and at a frequency of 250 Hz. Assuming that at the new voltage the maximum flux density is one-third of its original value and the resistivity of the core remains unaltered, determine the necessary new thickness of the laminations. //initializing the variables: Pe = 100; // in W/m3 f1 = 50; // in Hz t1 = 0.0005; // in m x = 1/3; f2 = 250; // in Hz //Assigning a sample value to Bm1 Bm1 = 1; //calculation: //Pe = ke*(Bm1*f1*t1)^2 //Hence, at 50 Hz frequency ke = Pe/(Bm1*f1*t1)^2 //At 250 Hz frequency //Bm2 = x*Bm1 t2 = ((Pe/ke)^0.5)/(Bm2*f2) printf("\n\n Result \n\n") printf("\nlamination thickness is %.2Em",t2)
