An Investigation on Stator Copper Loss by Using Different Stator Slot Size

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 reducing by increasing the stator slot size. This paper present the investigation on the stator copper loss effect between two different stator slot size which is 6mm and 8mm using 2D Finite Element Analysis (2D- FEA), model of 0.5hp induction motor.
