This document summarizes the development of a new solar powered water wheel aerator model, the Chaipattana RX-2-3. The original RX-2-2 model required a 2HP induction motor that was difficult to power with solar cells. The new RX-2-3 model uses a 150W universal motor that can be powered by a single 300W solar panel connected to a DC-DC converter. A new controller was also developed that can operate on input voltages from 100VDC to 55VDC from the solar panel. Simulation and testing showed the new solar powered system can operate for at least 8 hours and has higher oxygen transfer efficiencies than the original model.
1) The document discusses the development of a standalone solar-powered water wheel aerator called the Chaipattana RX-2-3.
2) The RX-2-3 aims to reduce power consumption and increase oxygen dissolved in water compared to previous models. It uses contra rotation to reduce torque on the fuselage.
3) The RX-2-3 is expected to efficiently operate daily using a 400W induction motor powered directly by two 300W PV panels without batteries. This model could see wider distribution due to its high efficiency and low cost.
