A copper rotor bar is fabricated and compared with the existing aluminium rotor bar through out this project. First aspect of comparison is done with software simulation using Opera 2D between aluminium rotor bar and copper rotor bar for the same 1.5HP stator slot design and winding configuration. The Opera 2D is compared in range of power loss, magnetic flux density, torque vs. speed, torque vs. slip, power loss vs. speed and power loss vs. slip. The second aspect is the hardware comparison between the fabricated copper rotor bars with the existing aluminium rotor bar. In this part, the copper rotor bar and aluminium rotor bar are tested using no load, blocked rotor, and DC resistance test to achive the difference of efficiency, losses and power factor improvement. From the overall experiment of software and hardware, results shows that copper rotor bar does increase the efficiency and power factor to 1.07 % and reduce losses to 11 watts compare to aluminium rotor bar. An economical aspect is presented to show the amount of energy and money that can be saved from replacing the aluminium rotor bar with a copper rotor bar. As for the annual energy saving (AES) and total cost saving (TCS), the copper rotor manage to save 124.51kWh per year and utility billing by RM41.76 per year per motor. Finally a rough estimation of 100,000 pieces induction motor that have been replaced with the copper rotor bars is assumed and shows that it will save approximately RM4.2 million.
