“…Induction machine efficiency is the measure of the ability of an induction machine to convert electrical energy to mechanical energy [1][2][3][4][5], i.e., watts of electric power are supplied to an induction machine at its electrical terminals, and the horsepower of mechanical energy is taken out of the induction machine at the rotating shaft. Therefore, the only power absorbed by the induction machine is the energy losses incurred in making the conversion from electrical to mechanical energy.…”

In This paper, the effect of corrosion on the magnetic behavior of a magnetic material used as a magnetic circuit in the induction machines is studied. With this objective, the magnetic properties of the samples with corrosion and without corrosion were evaluated by the study of hysteresis loops using a homemade vibrating sample magnetometer (VSM). The magnetic parameters extracted from the hysteresis loops such as saturation magnetization, coercive, remanent magnetization, squareness ratio, magnetic permeability, and hysteresis area were analyzed. It was shown that more energy is required to demagnetize the sample with corrosion than the sample without corrosion, and the hysteresis loss in the case of the sample with corrosion is more than the case of the sample without corrosion. These mean that when the corrosion is presented in the magnetic circuits of the induction machine, the hysteresis loss increases, consequentially reducing the machine efficiency.

“…Energy losses incurred in making the conversion from electrical to mechanical energy can be separated into three categories (1) mechanical losses, (2) winding losses, and (3) iron losses [6][7][8][9][10][11][12][13].…”
