AXIAL-FLOW WATER PUMP WITH A SCREW SHAFT DRIVEN BY A BRUSHLESS MOTOR. AXIAL-FLOW WATER PUMP WITH A SCREW SHAFT DRIVEN BY A BRUSHLESS MOTOR.

Abstract

            This research aimed to design and construct a Naga pipe water pump with a screw shaft of 5 inches in diameter and 3.6 meters in length, using solar power to drive a brushless motor. and evaluate the efficiency of the pump using a 3 HP. brushless motor. The system utilizes four 250 W. solar panels as the primary power source. During nighttime or in the absence of sunlight, the system can alternatively operate using 230 VAC electricity instead of solar power.

           Statistical analysis was conducted using mean and standard deviation. The assessment of the feasibility and suitability of the pump’s design, installation, and operation by experts indicated that the system achieved a good level of feasibility and suitability.
