Performance evaluation of its energy efficient was increased the attention as it will convey important energy and commercial funds. This research considered the effects of electrical steel sheet's thickness for rotor material of 0.5Hp 3-phase induction motor on energy efficiency, losses reductions and utility bill cost. The outcome for this research work is thru reducing the lamination thickness of steel sheet (from 0.50 mm to 0.35 mm) for rotor frame, the energy efficiency was increased by 1.4% and 13.27Watt of losses have been decreased. Uncertainty the new design is applied to 100, 000 pieces a new rotor of motor, it is assessed that 40.32kWh/year of energy might be saved also the utility bill will be saved up to RM 1.35million.

Its simplicity of use, self-starting, small in size, light in weight, high efficiency, less demanding maintenance, less prone to accidents and low cost per same power rating which usually met the required characteristics for industry as attract its application in industry. In Malaysia, about 48% of total energy is used to drive industrial motors. In many industrialized countries, more than 70% of the total energy is consumed by electric motors. It is available from fractional horse-power up to thousands of horse-power. Induction motor is employed in application such as centrifugal pumps, conveyors, compressor crushers, drilling machines, fans, blowers, escalators, refrigerator and electric vehicles. This work studies industrial low voltage three-phase induction motors with 4-pole, 0.5Hp, 50Hz and 415V.

These research paper shows the impact of lamination thickness on the voltage induced of power loss for the Non-Oriented Electrical Steel Sheet. This study was conducted by using Epstein test which is an outflow of flux investigated throughout the measurement of power loss at corner and limb likewise for each thickness. This data shows and is presented based on different frequency such as 45 Hz, 50 Hz and 55 Hz. It indicates that 0.50 mm lamination thickness has a lot of losses instead of 0.35 mm.

Comfort of practice, start-up, small, weightiness, Increased efficiency, low maintenance and inexpensive for each power rating that generally meets the necessary features for industries. Efficient improvements are inspected with copper for the rotor bars slot. Usually, the copper loss in the induction motor Rotor division contributes to the loss of energy. The research work was planned a new rotor design, by improved rotor bars type slot, size and design. These tasks were inspected using two approaches, in particular, MotorSolve (IM) and calculations in theory. One set of simulation has shown a significant increase in energy efficiency for a new rotor frame design. Calculations in theory are used MATLAB. As a result, these new designs have improved energy efficiency by 77% as compared to its 74% existing design. The results proved to be using MATLAB. For energy, cost savings and emission redu...
