Abstract
In this paper, the 0.5HP three phase AC induction motor have been investigated and analyzed.Through out this project, an induction motor is design by AutoCAD software and then simulated by using the FEM software.It is then compared with another conventionally used rotor bar. The first part of comparison is done with FEM Simulation by modeling the induction motor of aluminium rotor bar and copper rotor bar for the same 0.5HP configuration of stator slot design and winding configuration. The simulation is compared in terms of power loss, magnetic flux density, magnetic field intensity, eddy current density, torque vs. speed, torque vs. slip, power loss vs. speed and power loss vs. slip. From the overall experiment of software simulation, results shows that in the magnetic flux density (B) between the aluminium and copper rotor bars analysis, the high electrical conductivity can provide lower resistivity of the material, this means the copper rotor bars has lower impedance thus lower losses. The entire analysis shows some good benefits towards the usage of copper material rotor bars.
