| ABSTRACT |
The input power to an induction motor is in the form of three phase electric voltages and currents. The first losses encountered in the machine are I2R losses in the stator winding. The stator copper loss occurs when the stator windings is energized. This can be reduced by increasing the stator slot size. Through out this project an investigation on the stator region of an induction motor is done. Two Stators is design to determine the stator copper loss effect between two different stator slot size which is 6mm and 8mm by using 2D Finite Element Analysis (2D-FEA) and then a real model is fabricated. The real fabricated model is then investigated in a series of test to determine the stator copper loss between the two designs. Result shows that, the 8mm stator slot design can reduce the stator copper loss compared to 6mm by 1.1% and when assembled together with the designed rotor (0.35mm lamination steel sheet with 8mm rotor bar size) it shows a stunning increment of efficiency to 85% and losses reduction of 11.11W.
