Efficiency Increment on 0.35 mm and 0.50 mm Thicknesses of Non-oriented Steel Sheets for 0.5 Hp Induction Motor

Decreases of rotor steel laminations thicknesses will decrease the total loss and increases an induction motor efficiency. In this paper, two models of a three phase induction motor with different thickness of rotor steel laminations, 0.35 mm and 0.50 mm, have been thoroughly investigated and analyzed in term of efficiency, power factor and loss field. The comparison is done by using FEM software simulation and hardware experiments. Based on the results, it shows that the motor with 0.35 mm steel lamination rotor is more efficient compared to the 0.50 mm steel lamination rotor.
