Abstract

In this paper, the three phase AC induction motor have been thoroughly investigated and analyzed in terms of the induction motor parameter, efficiency and loss segregation. Through out this project, a new rotor which has 0.35mm lamination steel sheet and 10mm rotor bar size is fabricated and compared with the existing rotor which has 0.50mm and 10mm rotor bar size. The comparison is done by software simulation using Motorsolve (IM) Software between existing rotor bar and new rotor bar for the same 0.5HP stator slot design and winding configuration. The Motorsolve (IM) Software is compared in terms of efficiency, power factor and loss fields. Simulation analysis shows that the 0.35mm thicknesses steel sheet has an increment of 1.82% for the efficiency, an increment of 0.03 for the power factor and a decrement of 19.52% lamination eddy current loss as compared to that of 0.50mm steel sheet.
